A fortification (also called a fort , fortress , fastness , or stronghold ) is a military construction designed for the defense of territories in warfare , and is used to establish rule in a region during peacetime . The term is derived from Latin fortis ("strong") and facere ("to make").
228-466: A castle is a type of fortified structure built during the Middle Ages predominantly by the nobility or royalty and by military orders . Scholars usually consider a castle to be the private fortified residence of a lord or noble. This is distinct from a mansion , palace , and villa , whose main purpose was exclusively for pleasance and are not primarily fortresses but may be fortified. Use of
456-530: A Merovingian bride, and is one of the first Anglo-Saxon rulers who can be identified with some confidence. Bede and later sources portrayed Æthelberht as a descendant of the original group of "Saxons" mentioned by Gildas, although they apparently believed they were actually Jutish. Unfortunately the king lists and genealogies produced by Bede and later writers are not considered reliable for these early centuries. A 2022 genetic study used modern and ancient DNA samples from England and neighbouring countries to study
684-593: A drawbridge , although these were often replaced by stone bridges. The site of the 13th-century Caerphilly Castle in Wales covers over 30 acres (12 ha) and the water defences, created by flooding the valley to the south of the castle, are some of the largest in Western Europe. Battlements were most often found surmounting curtain walls and the tops of gatehouses, and comprised several elements: crenellations , hoardings , machicolations , and loopholes . Crenellation
912-430: A ravelin like angular gun platform screening one of the curtain walls which is protected from flanking fire from the towers of the main part of the fort. Another example is the fortifications of Rhodes which were frozen in 1522 so that Rhodes is the only European walled town that still shows the transition between the classical medieval fortification and the modern ones. A manual about the construction of fortification
1140-421: A "shameful habit" of drinking and eating in the outhouse, which some of the countrywomen practised at beer parties. In April 1016, Æthelred died of illness, leaving his son and successor Edmund Ironside to defend the country. The final struggles were complicated by internal dissension, and especially by the treacherous acts of Ealdorman Eadric of Mercia, who opportunistically changed sides to Cnut's party. After
1368-464: A Roman fort or Byzantine tetrapyrgia which were square in plan and had square towers at each corner that did not project much beyond the curtain wall. The keep of these Crusader castles would have had a square plan and generally be undecorated. While castles were used to hold a site and control movement of armies, in the Holy Land some key strategic positions were left unfortified. Castle architecture in
1596-458: A barbican was not just to provide another line of defence but also to dictate the only approach to the gate. A moat was a ditch surrounding a castle – or dividing one part of a castle from another – and could be either dry or filled with water. Its purpose often had a defensive purpose, preventing siege towers from reaching walls making mining harder, but could also be ornamental. Water moats were found in low-lying areas and were usually crossed by
1824-438: A central keep . In the late 12th and early 13th centuries, a scientific approach to castle defence emerged. This led to the proliferation of towers, with an emphasis on flanking fire . Many new castles were polygonal or relied on concentric defence – several stages of defence within each other that could all function at the same time to maximise the castle's firepower. These changes in defence have been attributed to
2052-610: A coalition of his enemies – Constantine , King of the Scots; Owain ap Dyfnwal , King of the Cumbrians; and Olaf Guthfrithson , King of Dublin – at the battle of Brunanburh , celebrated by a poem in the Anglo-Saxon Chronicle , opened the way for him to be hailed as the first king of England. Æthelstan's legislation shows how the king drove his officials to do their respective duties. He was uncompromising in his insistence on respect for
2280-486: A collective term, the compound term Anglo-Saxon , commonly used by modern historians for the period before 1066, first appears in Bede's time, but it was probably not widely used until modern times. Bede was one of the first writers to prefer " Angles " (or English) as the collective term, and this eventually became dominant. Bede, like other authors, also continued to use the collective term " Saxons ", especially when referring to
2508-494: A common collective term, and indeed became dominant. The increased use of these new collective terms, "English" or "Anglo-Saxon", represents the strengthening of the idea of a single unifying cultural unity among the Anglo-Saxons themselves, who had previously invested in identities which differentiated various regional groups. In contrast, Irish and Welsh speakers long continued to refer to Anglo-Saxons as Saxons. The word Saeson

#17328373247212736-569: A common origin, dealt with a particular mode of warfare, and exchanged influences. In different areas of the world, analogous structures shared features of fortification and other defining characteristics associated with the concept of a castle, though they originated in different periods and circumstances and experienced differing evolutions and influences. For example, shiro in Japan, described as castles by historian Stephen Turnbull , underwent "a completely different developmental history, were built in
2964-474: A completely different way and were designed to withstand attacks of a completely different nature". While European castles built from the late 12th and early 13th century onwards were generally stone, shiro were predominantly timber buildings into the 16th century. By the 16th century, when Japanese and European cultures met, fortification in Europe had moved beyond castles and relied on innovations such as
3192-636: A confined space and unable to retaliate. It is a popular myth that murder holes – openings in the ceiling of the gateway passage – were used to pour boiling oil or molten lead on attackers; the price of oil and lead and the distance of the gatehouse from fires meant that this was impractical. This method was, however, a common practice in Middle Eastern and Mediterranean castles and fortifications, where such resources were abundant. They were most likely used to drop objects on attackers, or to allow water to be poured on fires to extinguish them. Provision
3420-512: A double wall of trenches and ramparts, and in the Congo forests concealed ditches and paths, along with the main works, often bristled with rows of sharpened stakes. Inner defenses were laid out to blunt an enemy penetration with a maze of defensive walls allowing for entrapment and crossfire on opposing forces. A military tactic of the Ashanti was to create powerful log stockades at key points. This
3648-420: A formidable fighting force. At first, Alfred responded by the offer of repeated tribute payments. However, after a decisive victory at Edington in 878, Alfred offered vigorous opposition. He established a chain of fortresses across the south of England, reorganised the army, "so that always half its men were at home, and half out on service, except for those men who were to garrison the burhs", and in 896 ordered
3876-412: A fortification such as a city wall . The great hall was a large, decorated room where a lord received his guests. The hall represented the prestige, authority, and richness of the lord. Events such as feasts, banquets, social or ceremonial gatherings, meetings of the military council, and judicial trials were held in the great hall. Sometimes the great hall existed as a separate building, in that case, it
4104-518: A king, but who under the Alfredian regime was regarded as the 'ealdorman' of his people. The wealth of the monasteries and the success of Anglo-Saxon society attracted the attention of people from mainland Europe, mostly Danes and Norwegians. Because of the plundering raids that followed, the raiders attracted the name Viking – from the Old Norse víkingr meaning an expedition – which soon became used for
4332-409: A large part of Britain, and writing about Romano-British kingdoms which had been limited to the north and west. Other historians have argued that in the 5th century many Romano-British people must have adopted the new culture which we now call Anglo-Saxon, even when they did not have Germanic ancestry or rulers. Unfortunately, there are very few written sources apart from Gildas until the conversion of
4560-474: A letter addressed by Aldhelm to Hadrian that he too must be numbered among their students. Aldhelm wrote in elaborate and grandiloquent and very difficult Latin, which became the dominant style for centuries. Michael Drout states "Aldhelm wrote Latin hexameters better than anyone before in England (and possibly better than anyone since, or at least up until John Milton ). His work showed that scholars in England, at
4788-603: A long time in a constant state of alert"; elsewhere the lord's wife presided over a separate residence ( domus , aula or mansio in Latin) close to the keep, and the donjon was a barracks and headquarters. Gradually, the two functions merged into the same building, and the highest residential storeys had large windows; as a result for many structures, it is difficult to find an appropriate term. The massive internal spaces seen in many surviving donjons can be misleading; they would have been divided into several rooms by light partitions, as in
SECTION 20
#17328373247215016-434: A lord's home or hall was fire as it was usually a wooden structure. To protect against this, and keep other threats at bay, there were several courses of action available: create encircling earthworks to keep an enemy at a distance; build the hall in stone; or raise it up on an artificial mound, known as a motte, to present an obstacle to attackers. While the concept of ditches , ramparts , and stone walls as defensive measures
5244-535: A massive scale, utilising stone, wood, iron and earth in their construction. The Romans encountered fortified settlements such as hill forts and oppida when expanding their territory into northern Europe. Their defences were often effective, and were only overcome by the extensive use of siege engines and other siege warfare techniques, such as at the Battle of Alesia . The Romans' own fortifications ( castra ) varied from simple temporary earthworks thrown up by armies on
5472-602: A mission to Christianise the Kingdom of Northumbria from their native Anglo-Saxon paganism. Oswald had probably chosen Iona because after his father had been killed he had fled into south-west Scotland and had encountered Christianity, and had returned determined to make Northumbria Christian. Aidan achieved great success in spreading the Christian faith in the north, and since Aidan could not speak English and Oswald had learned Irish during his exile, Oswald acted as Aidan's interpreter when
5700-489: A mixture of castle technology from the Crusades , such as concentric fortification , and inspiration from earlier defences, such as Roman forts . Not all the elements of castle architecture were military in nature, so that devices such as moats evolved from their original purpose of defence into symbols of power. Some grand castles had long winding approaches intended to impress and dominate their landscape. Although gunpowder
5928-641: A modern office building. Even in some large castles the great hall was separated only by a partition from the lord's chamber, his bedroom and to some extent his office. Curtain walls were defensive walls enclosing a bailey. They had to be high enough to make scaling the walls with ladders difficult and thick enough to withstand bombardment from siege engines which, from the 15th century onwards, included gunpowder artillery . A typical wall could be 3 m (10 ft) thick and 12 m (39 ft) tall, although sizes varied greatly between castles. To protect them from undermining , curtain walls were sometimes given
6156-615: A monastery in Campania (near Naples). One of their first tasks at Canterbury was the establishment of a school; and according to Bede (writing some sixty years later), they soon "attracted a crowd of students into whose minds they daily poured the streams of wholesome learning". As evidence of their teaching, Bede reports that some of their students, who survived to his own day, were as fluent in Greek and Latin as in their native language. Bede does not mention Aldhelm in this connection; but we know from
6384-413: A necessity for many cities. Amnya Fort in western Siberia has been described by archaeologists as one of the oldest known fortified settlements, as well as the northernmost Stone Age fort. In Bulgaria, near the town of Provadia a walled fortified settlement today called Solnitsata starting from 4700 BC had a diameter of about 300 feet (91 m), was home to 350 people living in two-storey houses, and
6612-674: A new type of craft to be built which could oppose the Viking longships in shallow coastal waters. When the Vikings returned from the Continent in 892, they found they could no longer roam the country at will, for wherever they went they were opposed by a local army. After four years, the Scandinavians therefore split up, some to settle in Northumbria and East Anglia, the remainder to try their luck again on
6840-628: A number of casual references scattered throughout the Bede 's history to this aspect of Mercian military policy. Penda is found ravaging Northumbria as far north as Bamburgh and only a miraculous intervention from Aidan prevents the complete destruction of the settlement. In 676 Æthelred conducted a similar ravaging in Kent and caused such damage in the Rochester diocese that two successive bishops gave up their position because of lack of funds. In these accounts there
7068-529: A number of words in other languages also derive from castellum . The word castle was introduced into English shortly before the Norman Conquest of 1066 to denote this type of building, which was then new to England. In its simplest terms, the definition of a castle accepted amongst academics is "a private fortified residence". This contrasts with earlier fortifications, such as Anglo-Saxon burhs and walled cities such as Constantinople and Antioch in

7296-492: A range of purposes, the most important of which were military, administrative, and domestic. As well as defensive structures, castles were also offensive tools which could be used as a base of operations in enemy territory. Castles were established by Norman invaders of England for both defensive purposes and to pacify the country's inhabitants. As William the Conqueror advanced through England, he fortified key positions to secure
7524-556: A renaissance in classical knowledge. The growth and popularity of monasticism was not an entirely internal development, with influence from the continent shaping Anglo-Saxon monastic life. In 669 Theodore , a Greek-speaking monk originally from Tarsus in Asia Minor, arrived in Britain to become the eighth Archbishop of Canterbury . He was joined the following year by his colleague Hadrian, a Latin-speaking African by origin and former abbot of
7752-500: A reputation in Europe and showing that the English could write history and theology, and do astronomical computation (for the dates of Easter, among other things). During the 9th century, Wessex rose in power, from the foundations laid by King Egbert in the first quarter of the century to the achievements of King Alfred the Great in its closing decades. The outlines of the story are told in
7980-617: A result there were 4,000 in the country. There are very few castles dated with certainty from the mid-9th century. Converted into a donjon around 950, Château de Doué-la-Fontaine in France is the oldest standing castle in Europe . From 1000 onwards, references to castles in texts such as charters increased greatly. Historians have interpreted this as evidence of a sudden increase in the number of castles in Europe around this time; this has been supported by archaeological investigation which has dated
8208-531: A result, very very few kotas still stand to this day. Notable kotas: During Muhammad 's era in Arabia, many tribes made use of fortifications. In the Battle of the Trench , the largely outnumbered defenders of Medina, mainly Muslims led by Islamic prophet Muhammad, dug a trench , which together with Medina's natural fortifications, rendered the confederate cavalry (consisting of horses and camels ) useless, locking
8436-469: A scientific design. An example of this approach is Kerak . Although there were no scientific elements to its design, it was almost impregnable, and in 1187 Saladin chose to lay siege to the castle and starve out its garrison rather than risk an assault. During the late 11th and 12th centuries in what is now south-central Turkey the Hospitallers , Teutonic Knights and Templars established themselves in
8664-538: A series of straight lines creating the central fortified area that gives this style of fortification its name. Anglo-Saxons The Anglo-Saxons , in some contexts simply called Saxons or the English , were a cultural group who spoke Old English and inhabited much of what is now England and south-eastern Scotland in the Early Middle Ages . They traced their origins to Germanic settlers who became one of
8892-418: A stone skirt around their bases. Walkways along the tops of the curtain walls allowed defenders to rain missiles on enemies below, and battlements gave them further protection. Curtain walls were studded with towers to allow enfilading fire along the wall. Arrowslits in the walls did not become common in Europe until the 13th century, for fear that they might compromise the wall's strength. The entrance
9120-495: A stronghold and prison but was also a place where a knight or lord could entertain his peers. Over time the aesthetics of the design became more important, as the castle's appearance and size began to reflect the prestige and power of its occupant. Comfortable homes were often fashioned within their fortified walls. Although castles still provided protection from low levels of violence in later periods, eventually they were succeeded by country houses as high-status residences. Castle
9348-517: A turning point the continental ancestors of the Anglo-Saxons were probably quite diverse, and they arrived over a longer period. In another passage, Bede named pagan peoples still living in Germany ( Germania ) in the eighth century "from whom the Angles or Saxons, who now inhabit Britain, are known to have derived their origin; for which reason they are still corruptly called Garmans by the neighbouring nation of

9576-423: A wall with openings that allowed objects to be dropped on an enemy at the base of the wall in a similar fashion to hoardings. Arrowslits , also commonly called loopholes, were narrow vertical openings in defensive walls which allowed arrows or crossbow bolts to be fired on attackers. The narrow slits were intended to protect the defender by providing a very small target, but the size of the opening could also impede
9804-399: A wooden door. This led to the elevation of windows to the second storey – to make it harder to throw objects in – and to move the entrance from ground level to the second storey. These features are seen in many surviving castle keeps, which were the more sophisticated version of halls. Castles were not just defensive sites but also enhanced a lord's control over his lands. They allowed
10032-557: A working alliance between the West Saxon dynasty and the rulers of the Mercians. In 860, the eastern and western parts of the southern kingdom were united by agreement between the surviving sons of King Æthelwulf , though the union was not maintained without some opposition from within the dynasty; and in the late 870s King Alfred gained the submission of the Mercians under their ruler Æthelred , who in other circumstances might have been styled
10260-479: Is a corrupted form of "donjon" and means a dark, unwelcoming prison. Although often the strongest part of a castle and a last place of refuge if the outer defences fell, the keep was not left empty in case of attack but was used as a residence by the lord who owned the castle, or his guests or representatives. At first, this was usual only in England, when after the Norman Conquest of 1066 the "conquerors lived for
10488-491: Is a rare glimpse of the realities of early Anglo-Saxon overlordship and how a widespread overlordship could be established in a relatively short period. By the middle of the 8th century, other kingdoms of southern Britain were also affected by Mercian expansionism. The East Saxons seem to have lost control of London, Middlesex and Hertfordshire to Æthelbald, although the East Saxon homelands do not seem to have been affected, and
10716-500: Is also an intermediate branch known as semi-permanent fortification. Castles are fortifications which are regarded as being distinct from the generic fort or fortress in that they are a residence of a monarch or noble and command a specific defensive territory. Roman forts and hill forts were the main antecedents of castles in Europe, which emerged in the 9th century in the Carolingian Empire . The Early Middle Ages saw
10944-431: Is ancient, raising a motte is a medieval innovation. A bank and ditch enclosure was a simple form of defence, and when found without an associated motte is called a ringwork; when the site was in use for a prolonged period, it was sometimes replaced by a more complex structure or enhanced by the addition of a stone curtain wall. Building the hall in stone did not necessarily make it immune to fire as it still had windows and
11172-428: Is another example of a Gaulish fortified settlement. The term casemate wall is used in the archaeology of Israel and the wider Near East , having the meaning of a double wall protecting a city or fortress, with transverse walls separating the space between the walls into chambers. These could be used as such, for storage or residential purposes, or could be filled with soil and rocks during siege in order to raise
11400-493: Is employed when in the course of a campaign it becomes desirable to protect some locality with the best imitation of permanent defences that can be made in a short time, ample resources and skilled civilian labour being available. An example of this is the construction of Roman forts in England and in other Roman territories where camps were set up with the intention of staying for some time, but not permanently. Castles are fortifications which are regarded as being distinct from
11628-519: Is formally known as poliorcetics . In some texts, this latter term also applies to the art of building a fortification. Fortification is usually divided into two branches: permanent fortification and field fortification. Permanent fortifications are erected at leisure, with all the resources that a state can supply of constructive and mechanical skill, and are built of enduring materials. Field fortifications—for example breastworks —and often known as fieldworks or earthworks, are extemporized by troops in
SECTION 50
#173283732472111856-571: Is sometimes used as a catch-all term for all kinds of fortifications , and as a result has been misapplied in the technical sense. An example of this is Maiden Castle which, despite the name, is an Iron Age hill fort which had a very different origin and purpose. Although castle has not become a generic term for a manor house (like château in French and Schloss in German), many manor houses contain castle in their name while having few if any of
12084-579: Is the Heptarchy , which has not been used by scholars since the early 20th century as it gives the impression of a single political structure and does not afford the "opportunity to treat the history of any one kingdom as a whole". Simon Keynes suggests that the 8th and 9th century was a period of economic and social flourishing which created stability both below the Thames and above the Humber . Middle-lowland Britain
12312-407: Is the collective name for alternating crenels and merlons : gaps and solid blocks on top of a wall. Hoardings were wooden constructs that projected beyond the wall, allowing defenders to shoot at, or drop objects on, attackers at the base of the wall without having to lean perilously over the crenellations, thereby exposing themselves to retaliatory fire. Machicolations were stone projections on top of
12540-599: Is the modern Welsh word for "English people"; the equivalent word in Scottish Gaelic is Sasannach and in the Irish language , Sasanach . Catherine Hills suggests that it is no accident "that the English call themselves by the name sanctified by the Church, as that of a people chosen by God, whereas their enemies use the name originally applied to piratical raiders". Although it involved immigrant communities from northern Europe,
12768-595: The Anglo-Saxon Chronicle , though the annals represent a West Saxon point of view. On the day of Egbert's succession to the kingdom of Wessex, in 802, a Mercian ealdorman from the province of the Hwicce had crossed the border at Kempsford , with the intention of mounting a raid into northern Wiltshire ; the Mercian force was met by the local ealdorman, "and the people of Wiltshire had the victory". In 829, Egbert went on,
12996-890: The Armenian Kingdom of Cilicia , where they discovered an extensive network of sophisticated fortifications which had a profound impact on the architecture of Crusader castles . Most of the Armenian military sites in Cilicia are characterized by: multiple bailey walls laid with irregular plans to follow the sinuosities of the outcrops; rounded and especially horseshoe-shaped towers; finely-cut often rusticated ashlar facing stones with intricate poured cores; concealed postern gates and complex bent entrances with slot machicolations; embrasured loopholes for archers; barrel, pointed or groined vaults over undercrofts, gates and chapels; and cisterns with elaborate scarped drains. Civilian settlement are often found in
13224-482: The Bayeux Tapestry 's depiction of Château de Dinan . Sometimes a motte covered an older castle or hall, whose rooms became underground storage areas and prisons beneath a new keep. A bailey, also called a ward, was a fortified enclosure. It was a common feature of castles, and most had at least one. The keep on top of the motte was the domicile of the lord in charge of the castle and a bastion of last defence, while

Numerous Indus Valley Civilization sites exhibit evidence of fortifications. By about 3500 BC, hundreds of small farming villages dotted the Indus floodplain. Many of these settlements had fortifications and planned streets. The stone and mud brick houses of Kot Diji were clustered behind massive stone flood dykes and defensive walls, for neighbouring communities bickered constantly about
13680-587: The Danelaw . This was the " Great Army ", a term used by the Chronicle in England and by Adrevald of Fleury on the Continent. The invaders were able to exploit the feuds between and within the various kingdoms and to appoint puppet kings, such as Ceolwulf in Mercia in 873 and perhaps others in Northumbria in 867 and East Anglia in 870. The third phase was an era of settlement; however, the "Great Army" went wherever it could find
13908-569: The Frankish kingdom of Austrasia . Bede therefore called these the " Old Saxons " ( antiqui saxones ), and he noted that there was no longer any country of Angles in Germany, as it had become empty due to emigration. Similarly, a non-Anglo-Saxon contemporary of Bede, Paul the Deacon , referred variously to either the English ( Angli ), or Anglo-Saxons (Latin plural genitives Saxonum Anglorum , or Anglorum Saxonum ), which helped him distinguish them from

At the same time, the Roman administration in Britain (and other parts of the empire) was recruiting foederati soldiers from the same general regions in what is now Germany, and these are likely to have become more important after the withdrawal of field armies during internal Roman power struggles. According to the Chronica Gallica of 452 Britain was ravaged by Saxon invaders in 409 or 410. This

In ancient Greece , large stone walls had been built in Mycenaean Greece , such as the ancient site of Mycenae (known for the huge stone blocks of its ' cyclopean ' walls). A Greek phrourion was a fortified collection of buildings used as a military garrison , and is the equivalent of the Roman castellum or fortress. These constructions mainly served
14592-450: The Iron Age . Hillforts in Britain typically used earthworks rather than stone as a building material. Many earthworks survive today, along with evidence of palisades to accompany the ditches. In central and western Europe, oppida emerged in the 2nd century BC; these were densely inhabited fortified settlements, such as the oppidum of Manching . Some oppida walls were built on

He had been sent by Pope Gregory the Great to lead the Gregorian mission to Britain to Christianise the Kingdom of Kent from their native Anglo-Saxon paganism . Kent was probably chosen because Æthelberht had married a Christian princess, Bertha , daughter of Charibert I the king of Paris , who was expected to exert some influence over her husband. Æthelberht in Kent
15048-1147: The Maratha Empire . A large majority of forts in India are in North India. The most notable forts are the Red Fort at Old Delhi , the Red Fort at Agra , the Chittor Fort and Mehrangarh Fort in Rajasthan , the Ranthambhor Fort , Amer Fort and Jaisalmer Fort also in Rajasthan and Gwalior Fort in Madhya Pradesh . Arthashastra , the Indian treatise on military strategy describes six major types of forts differentiated by their major modes of defenses. Forts in Sri Lanka date back thousands of years, with many being built by Sri Lankan kings. These include several walled cities. With
15276-574: The Mediterranean . The fortifications were continuously being expanded and improved. Around 600 BC, in Heuneburg , Germany, forts were constructed with a limestone foundation supported by a mudbrick wall approximately 4 metres tall, probably topped by a roofed walkway, thus reaching a total height of 6 metres. The wall was clad with lime plaster, regularly renewed. Towers protruded outwards from it. The Oppidum of Manching (German: Oppidum von Manching)
15504-552: The Napoleonic wars . Most of the colonial forts were garrisoned up until the early 20th century. The coastal forts had coastal artillery manned by the Ceylon Garrison Artillery during the two world wars. Most of these were abandoned by the military but retained civil administrative officers, while others retained military garrisons, which were more administrative than operational. Some were reoccupied by military units with

The famous walls of the Forbidden City in Beijing were established in the early 15th century by the Yongle Emperor . The Forbidden City made up the inner portion of the Beijing city fortifications . During the Spanish Era several forts and outposts were built throughout the archipelago. Most notable is Intramuros ,
16188-427: The Romans . The gatehouse contained a series of defences to make a direct assault more difficult than battering down a simple gate. Typically, there were one or more portcullises – a wooden grille reinforced with metal to block a passage – and arrowslits to allow defenders to harry the enemy. The passage through the gatehouse was lengthened to increase the amount of time an assailant had to spend under fire in

The entire city of Kerma in Nubia (present day Sudan) was encompassed by fortified walls surrounded by a ditch. Archaeology has revealed various Bronze Age bastions and foundations constructed of stone together with either baked or unfired brick. The walls of Benin are described as

The Great Wall of China had been built since the Qin dynasty (221–207 BC), although its present form was mostly an engineering feat and remodelling of the Ming dynasty (1368–1644 AD). In addition to the Great Wall, a number of Chinese cities also employed the use of defensive walls to defend their cities. Notable Chinese city walls include the city walls of Hangzhou , Nanjing ,

Hadrian's Wall was built by the Roman Empire across the width of what is now northern England following a visit by Roman Emperor Hadrian (AD 76–138) in AD ;122.

17328-401: The "Great Wall of Brodgar" it was 4 metres (13 ft) thick and 4 metres tall. The wall had some symbolic or ritualistic function. The Assyrians deployed large labour forces to build new palaces , temples and defensive walls. In Bronze Age Malta , some settlements also began to be fortified. The most notable surviving example is Borġ in-Nadur , where a bastion built in around 1500 BC
17556-562: The "War of the Saxon Federates". Unlike Bede and later writers who followed him, for whom this war turned into a very long war between two nations which was eventually won by the descendants of the Saxons, Gildas reported that by the time he was born this war ended successfully for the Britons after the siege at 'Mons Badonicus' . (The price of peace, Higham argues, must have been a better treaty for
17784-497: The "proud tyrant" as Vortigern . However, the date could have been significantly earlier, and Bede's understanding of these events has been questioned. The Historia Brittonum , written in the 9th century, gives two different years, but the writer apparently believed it happened in 428. Another 9th century source, the Anglo-Saxon Chronicle is largely based on Bede but says this Saxon arrival happened in 449. The archaeological evidence suggests an earlier timescale. In particular,
18012-534: The 18th century onwards, there was a renewed interest in castles with the construction of mock castles, part of a Romantic revival of Gothic architecture , but they had no military purpose. The word castle is derived from the Latin word castellum , which is a diminutive of the word castrum , meaning "fortified place". The Old English castel , Occitan castel or chastel , French château , Spanish castillo , Portuguese castelo , Italian castello , and
18240-530: The 19th and early 20th centuries. The advances in modern warfare since World War I have made large-scale fortifications obsolete in most situations. Many United States Army installations are known as forts, although they are not always fortified. During the pioneering era of North America, many outposts on the frontiers, even non-military outposts, were referred to generically as forts. Larger military installations may be called fortresses; smaller ones were once known as fortalices. The word fortification can refer to
18468-537: The 4th century not with a specific country or nation, but with raiders in North Sea coastal areas of Britain and Gaul . An especially early reference to the Angli is the 6th-century Byzantine historian Procopius who however expressed doubts about the stories he had heard about events in the west, which he apparently heard through Frankish diplomats. He never mentions the Saxons, but he states that an island called Brittia, which
18696-465: The 9th and 10th centuries after the fall of the Carolingian Empire , which resulted in its territory being divided among individual lords and princes. These nobles built castles to control the area immediately surrounding them and they were both offensive and defensive structures: they provided a base from which raids could be launched as well as offered protection from enemies. Although their military origins are often emphasised in castle studies,
18924-538: The Anglo-Saxon period." In modern times, the term "Anglo-Saxons" is used by scholars to refer collectively to the Old English speaking groups in Britain. As a compound term it has the advantage of covering the various English-speaking groups on the one hand, and to avoid possible misunderstandings from using the terms "Saxons" or " Angles " (English), both of which terms could be used either as collectives referring to all
19152-503: The Anglo-Saxons to Christianity which began in the late 6th century. One eastern contemporary of Gildas, Procopius , reported a story which was apparently relayed to him by Frankish diplomats, that an island called Brittia which faced the Rhine was divided, between three peoples, the Britons, Anglii, and Frisians. Much later, Æthelberht of Kent (died 616) invited missionaries from the Pope and married
19380-655: The Britons": the Frisians , the Rugini , the Danes , the " Huns " ( Avars in this period), the "old Saxons", and the " Boructuari " who are presumed to be inhabitants of the old lands of the Bructeri , near the Lippe river. Gildas reported that a war broke out between the Saxons and the local population, who joined forces under a person named Ambrosius Aurelianus . Historian Nick Higham calls it
19608-595: The Christians were victorious in the First Crusade (1096–1099), rather than nearly 100 years later. Remains of Roman structures in Western Europe were still standing in many places, some of which had flanking round-towers and entrances between two flanking towers. The castle builders of Western Europe were aware of and influenced by Roman design; late Roman coastal forts on the English " Saxon Shore " were reused and in Spain
19836-502: The Continent. More important to Alfred than his military and political victories were his religion, his love of learning, and his spread of writing throughout England. Keynes suggests Alfred's work laid the foundations for what really made England unique in all of medieval Europe from around 800 until 1066. Thinking about how learning and culture had fallen since the last century, King Alfred wrote: ...So completely had wisdom fallen off in England that there were very few on this side of
20064-502: The Danes and that any charters issued in respect of such grants have not survived. When Athelflæd died, Mercia was absorbed by Wessex. From that point on there was no contest for the throne, so the house of Wessex became the ruling house of England. Edward the Elder was succeeded by his son Æthelstan , whom Keynes calls the "towering figure in the landscape of the tenth century". His victory over
20292-543: The East Saxon dynasty continued into the ninth century. The Mercian influence and reputation reached its peak when, in the late 8th century, the most powerful European ruler of the age, the Frankish king Charlemagne , recognised the Mercian King Offa 's power and accordingly treated him with respect, even if this could have been just flattery. Michael Drout calls this period the "Golden Age", when learning flourished with
20520-611: The East became more complex around the late 12th and early 13th centuries after the stalemate of the Third Crusade (1189–1192). Both Christians and Muslims created fortifications, and the character of each was different. Saphadin , the 13th-century ruler of the Saracens, created structures with large rectangular towers that influenced Muslim architecture and were copied again and again, however they had little influence on Crusader castles. In
20748-411: The Elder – who with his sister, Æthelflæd , Lady of the Mercians, initially, charters reveal, encouraged people to purchase estates from the Danes, thereby to reassert some degree of English influence in territory which had fallen under Danish control. David Dumville suggests that Edward may have extended this policy by rewarding his supporters with grants of land in the territories newly conquered from
20976-666: The English (Angle) migrants came from a country neighbouring those Saxons. Anglo-Saxon material culture can be seen in architecture , dress styles , illuminated texts, metalwork and other art . Behind the symbolic nature of these cultural emblems, there are strong elements of tribal and lordship ties. The elite declared themselves kings who developed burhs (fortifications and fortified settlements), and identified their roles and peoples in Biblical terms. Above all, as archaeologist Helena Hamerow has observed, "local and extended kin groups remained...the essential unit of production throughout
21204-522: The European Saxons who he also discussed. In England itself this compound term also came to be used in some specific situations, both in Latin and Old English. Alfred the Great , himself a West Saxon, was for example Anglosaxonum Rex in the late 880s, probably indicating that he was literally a king over both English (for example Mercian) and Saxon kingdoms. However, the term "English" continued to be used as
21432-538: The Great's Pastoral Care") What is presumed to be one of these "æstel" (the word only appears in this one text) is the gold, rock crystal and enamel Alfred Jewel , discovered in 1693, which is assumed to have been fitted with a small rod and used as a pointer when reading. Alfred provided functional patronage, linked to a social programme of vernacular literacy in England, which was unprecedented. Therefore it seems better to me, if it seems so to you, that we also translate certain books ...and bring it about ...if we have
21660-528: The Humber who could understand their rituals in English, or indeed could translate a letter from Latin into English; and I believe that there were not many beyond the Humber. There were so few of them that I indeed cannot think of a single one south of the Thames when I became king. (Preface: "Gregory the Great's Pastoral Care") Alfred knew that literature and learning, both in English and in Latin, were very important, but
21888-514: The Iberian Peninsula was the use of detached towers, called Albarrana towers , around the perimeter as can be seen at the Alcazaba of Badajoz . Probably developed in the 12th century, the towers provided flanking fire. They were connected to the castle by removable wooden bridges, so if the towers were captured the rest of the castle was not accessible. When seeking to explain this change in
22116-577: The Indus Valley Civilization were fortified. Forts also appeared in urban cities of the Gangetic valley during the second urbanisation period between 600 and 200 BC, and as many as 15 fortification sites have been identified by archaeologists throughout the Gangetic valley, such as Kaushambi , Mahasthangarh , Pataliputra , Mathura , Ahichchhatra , Rajgir , and Lauria Nandangarh . The earliest Mauryan period brick fortification occurs in one of
22344-458: The Ionan supporters, who did not change their practices, withdrew to Iona. Wilfred also influenced kings to the south who were under the dominance of Oswiu, such as the son of Penda, Wulfhere of Mercia (died 675), who converted to Christianity and eventually recovered control over Mercia, and eventually expanded his dominance over most of England, beginning a long period of Mercian supremacy . By 660,
22572-621: The Iron Age and peaking in Iron Age II (10th–6th century BC). However, the construction of casemate walls had begun to be replaced by sturdier solid walls by the 9th century BC , probably due the development of more effective battering rams by the Neo-Assyrian Empire . Casemate walls could surround an entire settlement, but most only protected part of it. The three different types included freestanding casemate walls, then integrated ones where
22800-469: The Italian trace italienne and star forts . A motte was an earthen mound with a flat top. It was often artificial, although sometimes it incorporated a pre-existing feature of the landscape. The excavation of earth to make the mound left a ditch around the motte, called a moat (which could be either wet or dry). Although the motte is commonly associated with the bailey to form a motte-and-bailey castle, this
23028-465: The Middle East; castles were not communal defences but were built and owned by the local feudal lords, either for themselves or for their monarch. Feudalism was the link between a lord and his vassal where, in return for military service and the expectation of loyalty, the lord would grant the vassal land. In the late 20th century, there was a trend to refine the definition of a castle by including
23256-461: The Old English speakers, or to specific tribal groups. Although the term "Anglo Saxon" was not used as a common term until modern times, it is not a modern invention because it was also used in some specific contexts already between the 8th and 10th centuries. Before the 8th century, the most common collective term for the Old-English speakers was "Saxons", which was a word originally associated since
23484-493: The Picts and Scots. Gildas did not report the year, and later writers (and modern historians) developed different estimates of when this occurred. Possibly referring to this same event, the Chronica Gallica of 452 records for the year 441: "The British provinces, which to this time had suffered various defeats and misfortunes, are reduced to Saxon rule". Bede, writing centuries later, reasoned that this happened in 450-455, and he named
23712-564: The Saxons, giving them the ability to receive tribute from people across the lowlands of Britain. ) Gildas himself did not mention the defeated Saxons as an ongoing problem, but instead he noted that the Britons had become divided into many small "tyrannies". His interest was in criticizing the Romano-British ruling class, whereas archaeological evidence shows that Anglo-Saxon culture had long become dominant over much of Britain. Historians who accept Bede's understanding interpret Gildas as ignoring
23940-399: The Scots, who had the capacity not merely to interfere in Northumbrian affairs, but also to block a line of communication between Dublin and York; and the inhabitants of northern Northumbria were considered a law unto themselves. It was only after twenty years of crucial developments following Æthelstan's death in 939 that a unified kingdom of England began to assume its familiar shape. However,
24168-508: The ancient site of Mycenae (famous for the huge stone blocks of its ' cyclopean ' walls). In classical era Greece , the city of Athens built two parallel stone walls, called the Long Walls , that reached their fortified seaport at Piraeus a few miles away. In Central Europe , the Celts built large fortified settlements known as oppida , whose walls seem partially influenced by those built in
24396-549: The archaeological record in Britain begins to indicate a relatively rapid melt-down of Roman material culture, and its replacement by Anglo-Saxon material culture. At some time between 445 and 454 Gildas , one of the only writers in this period, reported that the Britons also wrote to the Roman military leader Aëtius in Gaul, begging for assistance, with no success. In desperation, an un-named "proud tyrant" at some point invited Saxons as foederati soldiers to Britain to help defend it from
24624-403: The architectural characteristics, usually as their owners liked to maintain a link to the past and felt the term castle was a masculine expression of their power. In scholarship the castle, as defined above, is generally accepted as a coherent concept, originating in Europe and later spreading to parts of the Middle East, where they were introduced by European Crusaders. This coherent group shared
24852-410: The arrival of cannons on the 14th century battlefield . Fortifications in the age of black powder evolved into much lower structures with greater use of ditches and earth ramparts that would absorb and disperse the energy of cannon fire. Walls exposed to direct cannon fire were very vulnerable, so were sunk into ditches fronted by earth slopes. This placed a heavy emphasis on the geometry of
25080-426: The bailey was the home of the rest of the lord's household and gave them protection. The barracks for the garrison, stables, workshops, and storage facilities were often found in the bailey. Water was supplied by a well or cistern . Over time the focus of high status accommodation shifted from the keep to the bailey; this resulted in the creation of another bailey that separated the high status buildings – such as
25308-404: The chronicler reports, to conquer "the kingdom of the Mercians and everything south of the Humber". It was at this point that the chronicler chooses to attach Egbert's name to Bede's list of seven overlords, adding that "he was the eighth king who was Bretwalda ". Simon Keynes suggests Egbert's foundation of a 'bipartite' kingdom is crucial as it stretched across southern England, and it created
25536-563: The complexity and style of castles, antiquarians found their answer in the Crusades. It seemed that the Crusaders had learned much about fortification from their conflicts with the Saracens and exposure to Byzantine architecture . There were legends such as that of Lalys – an architect from Palestine who reputedly went to Wales after the Crusades and greatly enhanced the castles in the south of
25764-399: The conduct of government and warfare during Æthelred's reign. It is this evidence which is the basis for Keynes's view that the king lacked the strength, judgement and resolve to give adequate leadership to his people in a time of grave national crisis; who soon found out that he could rely on little but the treachery of his military commanders; and who, throughout his reign, tasted nothing but
25992-448: The construction of castle sites through the examination of ceramics. The increase in Italy began in the 950s, with numbers of castles increasing by a factor of three to five every 50 years, whereas in other parts of Europe such as France and Spain the growth was slower. In 950, Provence was home to 12 castles; by 1000, this figure had risen to 30, and by 1030 it was over 100. Although
26220-560: The control of prime agricultural land. The fortification varies by site. While Dholavira has stone-built fortification walls, Harrapa is fortified using baked bricks; sites such as Kalibangan exhibit mudbrick fortifications with bastions and Lothal has a quadrangular fortified layout. Evidence also suggested of fortifications in Mohenjo-daro . Even a small town—for instance, Kotada Bhadli, exhibiting sophisticated fortification-like bastions—shows that nearly all major and minor towns of
26448-474: The country – and it was assumed that great architects such as James of Saint George originated in the East. In the mid-20th century this view was cast into doubt. Legends were discredited, and in the case of James of Saint George it was proven that he came from Saint-Georges-d'Espéranche , in France. If the innovations in fortification had derived from the East, it would have been expected for their influence to be seen from 1100 onwards, immediately after
26676-407: The creation of some towns built around castles. Medieval-style fortifications were largely made obsolete by the arrival of cannons in the 14th century. Fortifications in the age of black powder evolved into much lower structures with greater use of ditches and earth ramparts that would absorb and disperse the energy of cannon fire. Walls exposed to direct cannon fire were very vulnerable, so
26904-407: The criterion of feudal ownership, thus tying castles to the medieval period; however, this does not necessarily reflect the terminology used in the medieval period. During the First Crusade (1096–1099), the Frankish armies encountered walled settlements and forts that they indiscriminately referred to as castles, but which would not be considered as such under the modern definition. Castles served
27132-475: The culture of the Anglo-Saxons was not transplanted from there, but rather developed in Britain. In 400, the Roman province of Britannia had long been part of the Roman Empire . Although the empire had been dismembered several times during the previous centuries, often because of usurpations beginning in Britain such as those of Magnus Maximus , and Constantine "III" there was an overall continuity and interconnectedness. Already before 400 Roman sources used
27360-931: The current level of military development. During the Renaissance era , the Venetian Republic raised great walls around cities, and the finest examples, among others, are in Nicosia (Cyprus), Rocca di Manerba del Garda (Lombardy), and Palmanova (Italy), or Dubrovnik (Croatia), which proved to be futile against attacks but still stand to this day. Unlike the Venetians, the Ottomans used to build smaller fortifications but in greater numbers, and only rarely fortified entire settlements such as Počitelj , Vratnik , and Jajce in Bosnia . Medieval-style fortifications were largely made obsolete by
27588-580: The death of Constantine "III" in 411, "the Romans never succeeded in recovering Britain, but it remained from that time under tyrants." The Romano-Britons nevertheless called upon the empire to help them fend off attacks from not only the Saxons , but also the Picts and Scoti . A hagiography of Saint Germanus of Auxerre claims that he helped command a defence against an invasion of Picts and Saxons in 429. By about 430
27816-614: The defeat of the English in the Battle of Assandun in October 1016, Edmund and Cnut agreed to divide the kingdom so that Edmund would rule Wessex and Cnut Mercia, but Edmund died soon after his defeat in November 1016, making it possible for Cnut to seize power over all England. In the 11th century, there were three conquests: one by Cnut on October 18, 1016; the second was an unsuccessful attempt of Battle of Stamford Bridge in September, 1066; and
28044-485: The defences be constructed far enough away from the fortress town to protect the inhabitants from bombardment by the besiegers, the range of whose guns was steadily increasing as better manufactured weapons were introduced. Threfore, since refortifying the Prussian fortress cities of Koblenz and Cologne after 1815, the principle of the ring fortress or girdle fortress was used: forts, each several hundred metres out from
28272-424: The defender if it was too small. A smaller horizontal opening could be added to give an archer a better view for aiming. Sometimes a sally port was included; this could allow the garrison to leave the castle and engage besieging forces. It was usual for the latrines to empty down the external walls of a castle and into the surrounding ditch. A postern is a secondary door or gate in a concealed location, usually in
28500-541: The direct predecessors of the high medieval Kingdom of England and the Middle English language. Although the modern English language owes less than 26% of its words to Old English, this includes the vast majority of everyday words. In the early 8th century, the earliest detailed account of Anglo-Saxon origins was given by Bede (d. 735), suggesting that they were long divided into smaller regional kingdoms, each with differing accounts of their continental origins. As
28728-549: The dominant form of castle in England, Wales, and Ireland well into the 12th century. At the same time, castle architecture in mainland Europe became more sophisticated. The donjon was at the centre of this change in castle architecture in the 12th century. Central towers proliferated, and typically had a square plan, with walls 3 to 4 m (9.8 to 13.1 ft) thick. Their decoration emulated Romanesque architecture , and sometimes incorporated double windows similar to those found in church bell towers. Donjons, which were
28956-449: The earliest periods of settlement. Roman and British writers of the 3rd to 6th century had described those earliest Saxons as North Sea raiders, and mercenaries. Later sources such as Bede believed these early raiders came from the region they called " Old Saxony ", in what is now northern Germany , which in their own time had become well-known as a region resisting the spread of Christianity and Frankish rule . According to this account,
29184-700: The early 13th century, Crusader castles were mostly built by Military Orders including the Knights Hospitaller , Knights Templar , and Teutonic Knights . The orders were responsible for the foundation of sites such as Krak des Chevaliers , Margat , and Belvoir . Design varied not just between orders, but between individual castles, though it was common for those founded in this period to have concentric defences. Fortification From very early history to modern times, defensive walls have often been necessary for cities to survive in an ever-changing world of invasion and conquest . Some settlements in
29412-411: The economy and justice. However, while castles proliferated in the 9th and 10th centuries the link between periods of insecurity and building fortifications is not always straightforward. Some high concentrations of castles occur in secure places, while some border regions had relatively few castles. It is likely that the castle evolved from the practice of fortifying a lordly home. The greatest threat to
29640-510: The error of his ways, leading to a period when the internal affairs of the kingdom appear to have prospered. The increasingly difficult times brought on by the Viking attacks are reflected in both Ælfric 's and Wulfstan 's works, but most notably in Wulfstan's fierce rhetoric in the Sermo Lupi ad Anglos , dated to 1014. Malcolm Godden suggests that ordinary people saw the return of the Vikings as
29868-704: The escalation of the Sri Lankan Civil War ; Jaffna fort , for example, came under siege several times. Large tempered earth (i.e. rammed earth ) walls were built in ancient China since the Shang dynasty ( c. 1600 –1050 BC); the capital at ancient Ao had enormous walls built in this fashion (see siege for more info). Although stone walls were built in China during the Warring States (481–221 BC), mass conversion to stone architecture did not begin in earnest until
30096-400: The field, perhaps assisted by such local labour and tools as may be procurable and with materials that do not require much preparation, such as soil, brushwood, and light timber , or sandbags (see sangar ). An example of field fortification was the construction of Fort Necessity by George Washington in 1754. There is also an intermediate branch known as semi-permanent fortification. This
30324-399: The first time following the Anglo-Saxon invasion, coins began circulating in Kent during his reign. His son-in-law Sæberht of Essex also converted to Christianity. After Æthelberht's death in about 616/618, the most powerful king was Rædwald of East Anglia , who also gave Christianity a foothold in his kingdom, and helped to install Edwin of Northumbria , who replaced Æthelfrith to become
30552-467: The fortification to allow defensive cannonry interlocking fields of fire to cover all approaches to the lower and thus more vulnerable walls. The evolution of this new style of fortification can be seen in transitional forts such as Sarzanello in North West Italy which was built between 1492 and 1502. Sarzanello consists of both crenellated walls with towers typical of the medieval period but also has
30780-521: The frontiers of the Nile Valley to protect against invaders from neighbouring territories, as well as circle-shaped mud brick walls around their cities. Many of the fortifications of the ancient world were built with mud brick, often leaving them no more than mounds of dirt for today's archaeologists. A massive prehistoric stone wall surrounded the ancient temple of Ness of Brodgar 3200 BC in Scotland . Named
31008-582: The garrison to control the surrounding area, and formed a centre of administration, providing the lord with a place to hold court . Building a castle sometimes required the permission of the king or other high authority. In 864 the King of West Francia, Charles the Bald , prohibited the construction of castella without his permission and ordered them all to be destroyed. This is perhaps the earliest reference to castles, though military historian R. Allen Brown points out that
31236-504: The generic fort or fortress in that it describes a residence of a monarch or noble and commands a specific defensive territory. An example of this is the massive medieval castle of Carcassonne . Defensive fences for protecting humans and domestic animals against predators was used long before the appearance of writing and began "perhaps with primitive man blocking the entrances of his caves for security from large carnivores ". From very early history to modern times, walls have been
31464-518: The height of the Maguindanao Sultanate 's power, they blanketed the areas around Western Mindanao with kotas and other fortifications to block the Spanish advance into the region. These kotas were usually made of stone and bamboo or other light materials and surrounded by trench networks. As a result, some of these kotas were burned easily or destroyed. With further Spanish campaigns in the region,
31692-419: The ignominy of defeat. The raids exposed tensions and weaknesses which went deep into the fabric of the late Anglo-Saxon state, and it is apparent that events proceeded against a background more complex than the chronicler probably knew. It seems, for example, that the death of Bishop Æthelwold in 984 had precipitated further reaction against certain ecclesiastical interests; that by 993 the king had come to regret
31920-626: The immediate proximity of these fortifications. After the First Crusade, Crusaders who did not return to their homes in Europe helped found the Crusader states of the Principality of Antioch , the County of Edessa , the Kingdom of Jerusalem , and the County of Tripoli . The castles they founded to secure their acquisitions were designed mostly by Syrian master-masons. Their design was very similar to that of
32148-456: The imminent "expectation of the apocalypse," and this was given voice in Ælfric and Wulfstan writings, which is similar to that of Gildas and Bede. Raids were taken as signs of God punishing his people; Ælfric refers to people adopting the customs of the Danish and exhorts people not to abandon the native customs on behalf of the Danish ones, and then requests a "brother Edward" to try to put an end to
32376-427: The increase was slower in Spain, the 1020s saw a particular growth in the number of castles in the region, particularly in contested border areas between Christian and Muslim lands. Despite the common period in which castles rose to prominence in Europe, their form and design varied from region to region. In the early 11th century, the motte and keep – an artificial mound with a palisade and tower on top –
32604-413: The inner wall was part of the outer buildings of the settlement, and finally filled casemate walls, where the rooms between the walls were filled with soil right away, allowing for a quick, but nevertheless stable construction of particularly high walls. The Romans fortified their cities with massive, mortar-bound stone walls. The most famous of these are the largely extant Aurelian Walls of Rome and
32832-411: The insistence of Athelstan, right at the end of his reign in 939. Between 970 and 973 a council was held, under the aegis of Edgar, where a set of rules were devised that would be applicable throughout England. This put all the monks and nuns in England under one set of detailed customs for the first time. In 973, Edgar received a special second, 'imperial coronation' at Bath , and from this point England
33060-428: The interaction of these settlers with the pre-existing Romano-British culture . By 1066, most of the people of what is now England spoke Old English, and were considered English. Viking and Norman invasions changed the politics and culture of England significantly, but the overarching Anglo-Saxon identity evolved and remained dominant even after the Norman Conquest. Late Anglo-Saxon political structures and language are
33288-402: The intervals between them. The arrival of explosive shells in the 19th century led to yet another stage in the evolution of fortification. Star forts did not fare well against the effects of high explosives and the intricate arrangements of bastions, flanking batteries and the carefully constructed lines of fire for the defending cannon could be rapidly disrupted by explosive shells. Worse,
33516-483: The kingdom of England was indeed made whole. In his formal address to the gathering at Winchester the king urged his bishops, abbots and abbesses "to be of one mind as regards monastic usage . . . lest differing ways of observing the customs of one Rule and one country should bring their holy conversation into disrepute". Athelstan's court had been an intellectual incubator. In that court were two young men named Dunstan and Æthelwold who were made priests, supposedly at
33744-441: The land he had taken. Between 1066 and 1087, he established 36 castles such as Warwick Castle , which he used to guard against rebellion in the English Midlands . Towards the end of the Middle Ages, castles tended to lose their military significance due to the advent of powerful cannons and permanent artillery fortifications; as a result, castles became more important as residences and statements of power. A castle could act as
33972-413: The large open ditches surrounding forts of this type were an integral part of the defensive scheme, as was the covered way at the edge of the counter scarp . The ditch was extremely vulnerable to bombardment with explosive shells. In response, military engineers evolved the polygonal style of fortification. The ditch became deep and vertically sided, cut directly into the native rock or soil, laid out as
34200-439: The latter was preaching. Later, Northumberland 's patron saint, Saint Cuthbert , was an abbot of the monastery, and then Bishop of Lindisfarne . An anonymous life of Cuthbert written at Lindisfarne is the oldest extant piece of English historical writing, and in his memory a gospel (known as the St Cuthbert Gospel ) was placed in his coffin. The decorated leather bookbinding is the oldest intact European binding. In 664,
34428-408: The law. However this legislation also reveals the persistent difficulties which confronted the king and his councillors in bringing a troublesome people under some form of control. His claim to be "king of the English" was by no means widely recognised. The situation was complex: the Hiberno-Norse rulers of Dublin still coveted their interests in the Danish kingdom of York ; terms had to be made with
34656-413: The lay of the land (the result was often irregular or curvilinear structures). The design of castles was not uniform, but these were features that could be found in a typical castle in the mid-12th century. By the end of the 12th century or the early 13th century, a newly constructed castle could be expected to be polygonal in shape, with towers at the corners to provide enfilading fire for
34884-519: The locals and immigrants were being buried together using the same new customs, and that they were having mixed children. The authors estimate the effective contributions to modern English ancestry are between 25% and 47% "north continental", 11% and 57% from British Iron Age ancestors, and 14% and 43% was attributed to a more stretched-out migration into southern England, from nearby populations such as modern Belgium and France. There were significant regional variations in north continental ancestry ― lower in
35112-496: The lord's chambers and the chapel – from the everyday structures such as the workshops and barracks. From the late 12th century there was a trend for knights to move out of the small houses they had previously occupied within the bailey to live in fortified houses in the countryside. Although often associated with the motte-and-bailey type of castle, baileys could also be found as independent defensive structures. These simple fortifications were called ringworks . The enceinte
35340-419: The loss of the donjon. Where keeps did exist, they were no longer square but polygonal or cylindrical. Gateways were more strongly defended, with the entrance to the castle usually between two half-round towers which were connected by a passage above the gateway – although there was great variety in the styles of gateway and entrances – and one or more portcullis. A peculiar feature of Muslim castles in
35568-428: The main antecedents of castles in Europe , which emerged in the 9th century in the Carolingian Empire . The Early Middle Ages saw the creation of some towns built around castles. These cities were only rarely protected by simple stone walls and more usually by a combination of both walls and ditches . From the 12th century, hundreds of settlements of all sizes were founded all across Europe, which very often obtained
35796-413: The main living quarters of the castle and usually the most strongly defended point of a castle before the introduction of concentric defence . "Keep" was not a term used in the medieval period – the term was applied from the 16th century onwards – instead " donjon " was used to refer to great towers, or turris in Latin. In motte-and-bailey castles, the keep was on top of the motte. "Dungeon"
36024-402: The major political problem for Edmund and Eadred , who succeeded Æthelstan, remained the difficulty of subjugating the north. In 959 Edgar is said to have "succeeded to the kingdom both in Wessex and in Mercia and in Northumbria, and he was then 16 years old" (ASC, version 'B', 'C'), and is called "the Peacemaker". By the early 970s, after a decade of Edgar's 'peace', it may have seemed that
36252-401: The most important cultural groups in Britain by the 5th century. The Anglo-Saxon period in Britain is considered to have started by about 450 and ended in 1066, with the Norman Conquest . Although the details of their early settlement and political development are not clear, by the 8th century a single Anglo-Saxon cultural identity which was generally called Englisc had developed out of
36480-417: The most powerful and influential women in Europe. Double monasteries which were built on strategic sites near rivers and coasts, accumulated immense wealth and power over multiple generations (their inheritances were not divided) and became centers of art and learning. While Aldhelm was doing his work in Malmesbury , far from him, up in the North of England, Bede was writing a large quantity of books, gaining
36708-443: The move, to elaborate permanent stone constructions, notably the milecastles of Hadrian's Wall . Roman forts were generally rectangular with rounded corners – a "playing-card shape". In the medieval period, castles were influenced by earlier forms of elite architecture, contributing to regional variations. Importantly, while castles had military aspects, they contained a recognisable household structure within their walls, reflecting
36936-436: The multi-functional use of these buildings. The subject of the emergence of castles in Europe is a complex matter which has led to considerable debate. Discussions have typically attributed the rise of the castle to a reaction to attacks by Magyars , Muslims , and Vikings and a need for private defence. The breakdown of the Carolingian Empire led to the privatisation of government, and local lords assumed responsibility for
37164-521: The number of castles being built went into decline. This has been partly attributed to the higher cost of stone-built fortifications, and the obsolescence of timber and earthwork sites, which meant it was preferable to build in more durable stone. Although superseded by their stone successors, timber and earthwork castles were by no means useless. This is evidenced by the continual maintenance of timber castles over long periods, sometimes several centuries; Owain Glyndŵr 's 11th-century timber castle at Sycharth
37392-411: The old walled city of Manila located along the southern bank of the Pasig River . The historic city was home to centuries-old churches, schools, convents, government buildings and residences, the best collection of Spanish colonial architecture before much of it was destroyed by the bombs of World War II . Of all the buildings within the 67-acre city, only one building, the San Agustin Church, survived
37620-440: The original enceinte, were carefully sited so as to make best use of the terrain and to be capable of mutual support with the neighbouring forts. Gone were citadels surrounding towns: forts were to be moved to the outside of the cities some 12 km to keep the enemy at a distance so their artillery could not bombard the city center. From now on a ring of forts were to be built at a spacing that would allow them to effectively cover
37848-451: The outset of colonial rule in the Indian Ocean , Sri Lanka was occupied by several major colonial empires that from time to time became the dominant power in the Indian Ocean. The colonists built several western-style forts, mostly in and around the coast of the island. The first to build colonial forts in Sri Lanka were the Portuguese ; these forts were captured and later expanded by the Dutch . The British occupied these Dutch forts during
38076-478: The overall group in Britain as the "English" people (Latin Angli , gens Anglorum or Old English Angelcynn ). In Bede's work the term "Saxon" is also used to refer sometimes to the Old English language, and also to refer to the early pagan Anglo-Saxons before the arrival of Christian missionaries among the Anglo-Saxons of Kent in 597. The term "Saxon", on the other hand, was at this time increasingly used by mainland writers to designate specific northern neighbours of
38304-424: The peace, that all the youth of free men who now are in England, those who have the means that they may apply themselves to it, be set to learning, while they may not be set to any other use, until the time when they can well read English writings. (Preface: "Gregory the Great's Pastoral Care") This began a growth in charters, law, theology and learning. Alfred thus laid the foundation for the great accomplishments of
38532-473: The people to their knees in 1009–12, when a large part of the country was devastated by the army of Thorkell the Tall . It remained for Swein Forkbeard , king of Denmark, to conquer the kingdom of England in 1013–14, and (after Æthelred's restoration) for his son Cnut to achieve the same in 1015–16. The tale of these years incorporated in the Anglo-Saxon Chronicle must be read in its own right, and set beside other material which reflects in one way or another on
38760-487: The people's sins, raising awareness of a collective Christian identity; and by 'conquering' the kingdoms of the East Angles, the Northumbrians and the Mercians, they created a vacuum in the leadership of the English people. Danish settlement continued in Mercia in 877 and East Anglia in 879—80 and 896. The rest of the army meanwhile continued to harry and plunder on both sides of the Channel, with new recruits evidently arriving to swell its ranks, for it clearly continued to be
38988-408: The political map of Lowland Britain had developed with smaller territories coalescing into kingdoms, and from this time larger kingdoms started dominating the smaller kingdoms. The development of kingdoms, with a particular king being recognised as an overlord, developed out of an early loose structure that, Higham believes, is linked back to the original feodus . The traditional name for this period
39216-409: The practice of improving an area's defense with defensive works. City walls are fortifications but are not necessarily called fortresses. The art of setting out a military camp or constructing a fortification traditionally has been called castrametation since the time of the Roman legions . Laying siege to a fortification and of destroying it is commonly called siegecraft or siege warfare and
39444-467: The preface: ...When I had learned it I translated it into English, just as I had understood it, and as I could most meaningfully render it. And I will send one to each bishopric in my kingdom, and in each will be an æstel worth fifty mancuses. And I command in God's name that no man may take the æstel from the book nor the book from the church. It is unknown how long there may be such learned bishops as, thanks to God, are nearly everywhere. (Preface: "Gregory
39672-471: The purpose of a watch tower, to guard certain roads, passes, and borders. Though smaller than a real fortress, they acted as a border guard rather than a real strongpoint to watch and maintain the border. The art of setting out a military camp or constructing a fortification traditionally has been called "castrametation" since the time of the Roman legions . Fortification is usually divided into two branches: permanent fortification and field fortification. There
39900-416: The question of physical Anglo-Saxon migration and concluded that there was large-scale immigration of both men and women into Eastern England, from a "north continental" population matching early medieval people from the area stretching from northern Netherlands through northern Germany to Denmark. This began already in the Roman era, and then increased rapidly in the 5th century. The burial evidence showed that
40128-423: The raiding activity or piracy reported in western Europe. In 793, Lindisfarne was raided and while this was not the first raid of its type it was the most prominent. In 794, Jarrow, the monastery where Bede wrote, was attacked; in 795 Iona in Scotland was attacked; and in 804 the nunnery at Lyminge in Kent was granted refuge inside the walls of Canterbury. Sometime around 800, a Reeve from Portland in Wessex
40356-422: The residence of the lord of the castle, evolved to become more spacious. The design emphasis of donjons changed to reflect a shift from functional to decorative requirements, imposing a symbol of lordly power upon the landscape. This sometimes led to compromising defence for the sake of display. Until the 12th century, stone-built and earth and timber castles were contemporary, but by the late 12th century
40584-468: The resistance of the outer wall against battering rams. Originally thought to have been introduced to the region by the Hittites , this has been disproved by the discovery of examples predating their arrival, the earliest being at Ti'inik (Taanach) where such a wall has been dated to the 16th century BC . Casemate walls became a common type of fortification in the Southern Levant between the Middle Bronze Age (MB) and Iron Age II, being more numerous during
40812-463: The richest pickings, crossing the English Channel when faced with resolute opposition, as in England in 878, or with famine, as on the Continent in 892. By this stage, the Vikings were assuming ever increasing importance as catalysts of social and political change. They constituted the common enemy, making the English more conscious of a national identity which overrode deeper distinctions; they could be perceived as an instrument of divine punishment for
41040-429: The right of fortification soon afterward. The founding of urban centres was an important means of territorial expansion and many cities, especially in eastern Europe , were founded precisely for this purpose during the period of Eastern Colonisation . These cities are easy to recognise due to their regular layout and large market spaces. The fortifications of these settlements were continuously improved to reflect
41268-414: The second king over the two kingdoms north of the Humber, Bernicia and Deira . After Rædwald died, Cadwallon ap Cadfan, the king of Gwynedd , in alliance with king Penda of Mercia , killed Edwin in battle at Hatfield Chase . Æthelfrith's son Oswald subsequently became the third king of Northumbria. Although not included in Bede's list of rulers with imperium, Penda defeated and killed Oswald in 642 and
41496-430: The southern Danelaw, and finally over Northumbria, thereby imposing a semblance of political unity on peoples, who nonetheless would remain conscious of their respective customs and their separate pasts. The prestige, and indeed the pretensions, of the monarchy increased, the institutions of government strengthened, and kings and their agents sought in various ways to establish social order. This process started with Edward
41724-476: The state of learning was not good when Alfred came to the throne. Alfred saw kingship as a priestly office, a shepherd for his people. One book that was particularly valuable to him was Gregory the Great's Cura Pastoralis (Pastoral Care). This is a priest's guide on how to care for people. Alfred took this book as his own guide on how to be a good king to his people; hence, a good king to Alfred increases literacy. Alfred translated this book himself and explains in
41952-435: The stockades by mounting old-fashioned bayonet charges, after laying down some covering fire. Defensive works were of importance in the tropical African Kingdoms. In the Kingdom of Kongo field fortifications were characterized by trenches and low earthen embankments. Such strongpoints ironically, sometimes held up much better against European cannon than taller, more imposing structures. Roman forts and hill forts were
42180-542: The structures also served as centres of administration and symbols of power. Urban castles were used to control the local populace and important travel routes, and rural castles were often situated near features that were integral to life in the community, such as mills, fertile land, or a water source. Many northern European castles were originally built from earth and timber but had their defences replaced later by stone . Early castles often exploited natural defences, lacking features such as towers and arrowslits and relying on
42408-438: The stupa mounds of Lauria Nandangarh, which is 1.6 km in perimeter and oval in plan and encloses a habitation area. Mundigak ( c. 2500 BC ) in present-day south-east Afghanistan has defensive walls and square bastions of sun dried bricks. India currently has over 180 forts, with the state of Maharashtra alone having over 70 forts, which are also known as durg , many of them built by Shivaji , founder of
42636-525: The sultanate was subdued and a majority of kotas dismantled or destroyed. kotas were not only used by the Muslims as defense against Spaniards and other foreigners, renegades and rebels also built fortifications in defiance of other chiefs in the area. During the American occupation, rebels built strongholds and the datus, rajahs, or sultans often built and reinforced their kotas in a desperate bid to maintain rule over their subjects and their land. Many of these forts were also destroyed by American expeditions, as
42864-440: The surviving works of Anglo-Latin and vernacular literature, as well as the numerous manuscripts written in the 10th century, testify in their different ways to the vitality of ecclesiastical culture. Yet as Keynes suggests "it does not follow that the 10th century is better understood than more sparsely documented periods". During the course of the 10th century, the West Saxon kings extended their power first over Mercia, then into
43092-528: The tenth century and did much to make the vernacular more important than Latin in Anglo-Saxon culture. I desired to live worthily as long as I lived, and to leave after my life, to the men who should come after me, the memory of me in good works. (Preface: "The Consolation of Philosophy by Boethius") A framework for the momentous events of the 10th and 11th centuries is provided by the Anglo-Saxon Chronicle . However charters, law-codes and coins supply detailed information on various aspects of royal government, and
43320-426: The term Saxons to refer to coastal raiders who had been causing problems especially on the coasts of the North Sea . In what is now south-eastern England the Romans established a military commander who was assigned to oversee a chain of coastal forts which they called the Saxon shore . The homeland of these Saxon raiders was not clearly described in surviving sources but they were apparently the northerly neighbours of
43548-410: The term has varied over time and, sometimes, has also been applied to structures such as hill forts and 19th- and 20th-century homes built to resemble castles. Over the Middle Ages, when genuine castles were built, they took on a great many forms with many different features, although some, such as curtain walls , arrowslits , and portcullises , were commonplace. European-style castles originated in
43776-399: The third was conducted by William of Normandy in October, 1066 at Hastings. The consequences of each conquest changed the Anglo-Saxon culture. Politically and chronologically, the texts of this period are not Anglo-Saxon; linguistically, those written in English (as opposed to Latin or French, the other official written languages of the period) moved away from the late West Saxon standard that
44004-401: The time of Magnus Maximus in the late 4th century. Bede, whose report of this period is partly based on Gildas, believed that the call was answered by kings from three powerful tribes from Germania, Angles, Saxons, and Jutes. The Saxons came from Old Saxony on the North Sea coast of Germany, and settled in Wessex , Sussex and Essex . Jutland , the peninsula containing part of Denmark,
44232-405: The two sides in a stalemate. Hoping to make several attacks at once, the confederates persuaded the Medina-allied Banu Qurayza to attack the city from the south. However, Muhammad's diplomacy derailed the negotiations, and broke up the confederacy against him. The well-organized defenders, the sinking of confederate morale, and poor weather conditions caused the siege to end in a fiasco. During
44460-530: The very edge of Europe, could be as learned and sophisticated as any writers in Europe." During this period, the wealth and power of the monasteries increased as elite families, possibly out of power, turned to monastic life. Anglo-Saxon monasticism developed the unusual institution of the "double monastery": a house of monks and a house of nuns, living next to each other, sharing a church but never mixing, and living separate lives of celibacy. These double monasteries were presided over by abbesses, who became some of
44688-462: The wall around the city of Ávila imitated Roman architecture when it was built in 1091. Historian Smail in Crusading warfare argued that the case for the influence of Eastern fortification on the West has been overstated, and that Crusaders of the 12th century in fact learned very little about scientific design from Byzantine and Saracen defences. A well-sited castle that made use of natural defences and had strong ditches and walls had no need for
44916-499: The walls were sunk into ditches fronted by earth slopes to improve protection. The arrival of explosive shells in the 19th century led to another stage in the evolution of fortification. Star forts did not fare well against the effects of high explosives, and the intricate arrangements of bastions, flanking batteries and the carefully constructed lines of fire for the defending cannon could be rapidly disrupted by explosive shells. Steel -and- concrete fortifications were common during
45144-412: The walls. The towers would have protruded from the walls and featured arrowslits on each level to allow archers to target anyone nearing or at the curtain wall. These later castles did not always have a keep, but this may have been because the more complex design of the castle as a whole drove up costs and the keep was sacrificed to save money. The larger towers provided space for habitation to make up for
45372-559: The war. Partial listing of Spanish forts: The Ivatan people of the northern islands of Batanes built their so-called idjang on hills and elevated areas to protect themselves during times of war. These fortifications were likened to European castles because of their purpose. Usually, the only entrance to the castles would be via a rope ladder that would only be lowered for the villagers and could be kept away when invaders arrived. The Igorots built forts made of stone walls that averaged several meters in width and about two to three times
45600-470: The west, and highest in Sussex, the East Midlands and East Anglia. From the time of the Christian conversions the first well-attested English kings and kingdoms appear in the written record. This situation with a small number of kingdoms competing for dominance is traditionally called the Heptarchy , which indicates a period of seven kingdoms. There were however more than seven kingdoms, and their interactions were quite complex. In 595 Augustine landed on
45828-410: The width in height around 2000 BC. The Muslim Filipinos of the south built strong fortresses called kota or moong to protect their communities. Usually, many of the occupants of these kotas are entire families rather than just warriors. Lords often had their own kotas to assert their right to rule, it served not only as a military installation but as a palace for the local Lord. It is said that at
46056-459: The word castella may have applied to any fortification at the time. In some countries the monarch had little control over lords, or required the construction of new castles to aid in securing the land so was unconcerned about granting permission – as was the case in England in the aftermath of the Norman Conquest and the Holy Land during the Crusades . Switzerland is an extreme case of there being no state control over who built castles, and as
46284-399: The work of Catherine Hills and Sam Lucy on the evidence of Spong Hill has moved the chronology for the settlement earlier than 450, with a significant number of items now in phases before Bede's date. Historian Guy Halsall has even speculated that Gildas was badly misread by Bede and all subsequent historians, and that the invitation of the foederati was part of a military reorganization in
46512-572: The world's second longest man-made structure, as well as the most extensive earthwork in the world, by the Guinness Book of Records, 1974 . The walls may have been constructed between the thirteenth and mid-fifteenth century CE or, during the first millennium CE. Strong citadels were also built other in areas of Africa. Yorubaland for example had several sites surrounded by the full range of earthworks and ramparts seen elsewhere, and sited on ground. This improved defensive potential—such as hills and ridges. Yoruba fortifications were often protected with
46740-430: Was a large Celtic proto-urban or city-like settlement at modern-day Manching (near Ingolstadt), Bavaria (Germany). The settlement was founded in the 3rd century BC and existed until c. 50–30 BC . It reached its largest extent during the late La Tène period (late 2nd century BC), when it had a size of 380 hectares. At that time, 5,000 to 10,000 people lived within its 7.2 km long walls. The oppidum of Bibracte
46968-440: Was called a hall-house. Historian Charles Coulson states that the accumulation of wealth and resources, such as food, led to the need for defensive structures. The earliest fortifications originated in the Fertile Crescent , the Indus Valley , Europe, Egypt, and China where settlements were protected by large walls. In Northern Europe , hill forts were first developed in the Bronze Age , which then proliferated across Europe in
47196-419: Was common, and usually between local lords. Castles were introduced into England shortly before the Norman Conquest in 1066. Before the 12th century castles were as uncommon in Denmark as they had been in England before the Norman Conquest. The introduction of castles to Denmark was a reaction to attacks from Wendish pirates, and they were usually intended as coastal defences. The motte and bailey remained
47424-571: Was dominant over the southern kingdoms. At the time of the battle of the river Winwæd, thirty duces regii (royal generals) fought on his behalf. Although there are many gaps in the evidence, it is clear that the seventh-century Mercian kings were formidable rulers who were able to exercise a wide-ranging overlordship from their Midland base. Mercian military success was the basis of their power; it succeeded against not only 106 kings and kingdoms by winning set-piece battles, but by ruthlessly ravaging any area foolish enough to withhold tribute. There are
47652-549: Was employed in later wars against the British to block British advances. Some of these fortifications were over a hundred yards long, with heavy parallel tree trunks. They were impervious to destruction by artillery fire. Behind these stockades, numerous Ashanti soldiers were mobilized to check enemy movement. While formidable in construction, many of these strongpoints failed because Ashanti guns, gunpowder and bullets were poor, and provided little sustained killing power in defense. Time and time again British troops overcame or bypassed
47880-468: Was encircled by a fortified wall. The huge walls around the settlement, which were built very tall and with stone blocks which are 6 feet (1.8 m) high and 4.5 feet (1.4 m) thick, make it one of the earliest walled settlements in Europe but it is younger than the walled town of Sesklo in Greece from 6800 BC. Uruk in ancient Sumer ( Mesopotamia ) is one of the world's oldest known walled cities . The Ancient Egyptians also built fortresses on
48108-435: Was found. Exceptions were few—notably, ancient Sparta and ancient Rome did not have walls for a long time, choosing to rely on their militaries for defence instead. Initially, these fortifications were simple constructions of wood and earth, which were later replaced by mixed constructions of stones piled on top of each other without mortar . In ancient Greece , large stone walls had been built in Mycenaean Greece , such as
48336-427: Was in short supply. Although stone construction would later become common elsewhere, from the 11th century onwards it was the primary building material for Christian castles in Spain, while at the same time timber was still the dominant building material in north-west Europe. Historians have interpreted the widespread presence of castles across Europe in the 11th and 12th centuries as evidence that warfare
48564-556: Was introduced to Europe in the 14th century, it did not significantly affect castle building until the 15th century, when artillery became powerful enough to break through stone walls. While castles continued to be built well into the 16th century, new techniques to deal with improved cannon fire made them uncomfortable and undesirable places to live. As a result, true castles went into decline and were replaced by artillery star forts with no role in civil administration, and château or country houses that were indefensible. From
48792-426: Was killed when he mistook some raiders for ordinary traders. Viking raids continued until in 850, then the Chronicle says: "The heathen for the first time remained over the winter". The fleet does not appear to have stayed long in England, but it started a trend which others subsequently followed. In particular, the army which arrived in 865 remained over many winters, and part of it later settled what became known as
49020-427: Was known as the place of the Mierce , the border or frontier folk, in Latin Mercia. Mercia was a diverse area of tribal groups, as shown by the Tribal Hidage; the peoples were a mixture of Brittonic speaking peoples and "Anglo-Saxon" pioneers and their early leaders had Brittonic names, such as Penda . Although Penda does not appear in Bede's list of great overlords, it would appear from what Bede says elsewhere that he
49248-476: Was later seen by Bede as the third king to have imperium over the English south of the Humber , having replaced Ceawlin of Wessex (died about 593), and before this generation there are only semi-mythical accounts of earlier kings. Æthelberht's law for Kent, the earliest written code in any Germanic language , instituted a complex system of fines. Kent was rich, with strong trade ties to the continent, and Æthelberht may have instituted royal control over trade. For
49476-417: Was made in the upper storey of the gatehouse for accommodation so the gate was never left undefended, although this arrangement later evolved to become more comfortable at the expense of defence. During the 13th and 14th centuries the barbican was developed. This consisted of a rampart , ditch, and possibly a tower, in front of the gatehouse which could be used to further protect the entrance. The purpose of
49704-417: Was not always the case and there are instances where a motte existed on its own. "Motte" refers to the mound alone, but it was often surmounted by a fortified structure, such as a keep, and the flat top would be surrounded by a palisade . It was common for the motte to be reached over a flying bridge (a bridge over the ditch from the counterscarp of the ditch to the edge of the top of the mound), as shown in
49932-417: Was often the weakest part in a circuit of defences. To overcome this, the gatehouse was developed, allowing those inside the castle to control the flow of traffic. In earth and timber castles, the gateway was usually the first feature to be rebuilt in stone. The front of the gateway was a blind spot and to overcome this, projecting towers were added on each side of the gate in a style similar to that developed by
50160-449: Was only a few years after Constantine "III" was declared Roman emperor in Britain, and during the period that he was still leading British Roman forces in rebellion on the continent. The rebellion was soon quashed, the Romano-British citizens reportedly expelled Constantine's imperial officials during this period, but they never again received new Roman officials or military forces. Writing in the mid-sixth century, Procopius states that after
50388-478: Was published by Giovanni Battista Zanchi in 1554. Fortifications also extended in depth, with protected batteries for defensive cannonry, to allow them to engage attacking cannons to keep them at a distance and prevent them from bearing directly on the vulnerable walls. The result was star shaped fortifications with tier upon tier of hornworks and bastions , of which Fort Bourtange is an excellent example. There are also extensive fortifications from this era in
50616-400: Was ruled by Edgar under the strong influence of Dunstan, Athelwold, and Oswald , the Bishop of Worcester. The reign of King Æthelred the Unready witnessed the resumption of Viking raids on England, putting the country and its leadership under strains as severe as they were long sustained. Raids began on a relatively small scale in the 980s but became far more serious in the 990s, and brought
50844-420: Was still in use by the start of the 15th century, its structure having been maintained for four centuries. At the same time there was a change in castle architecture. Until the late 12th century castles generally had few towers; a gateway with few defensive features such as arrowslits or a portcullis; a great keep or donjon, usually square and without arrowslits; and the shape would have been dictated by
51072-480: Was supposedly distinct from Britain itself, was settled by three nations: the Angili, Frissones, and Brittones, each ruled by its own king. Each nation was so prolific that it sent large numbers of individuals every year to the Franks, who planted them in unpopulated regions of their territory. By the 8th century the Saxons in Germany were seen as a country, and writers such as Bede and some of his contemporaries including Alcuin , and Saint Boniface , began to refer to
51300-423: Was the castle's main defensive enclosure, and the terms "bailey" and "enceinte" are linked. A castle could have several baileys but only one enceinte.
