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").
155-459: A hillfort is a type of fortified refuge or defended settlement located to exploit a rise in elevation for defensive advantage. They are typical of the late European Bronze Age and Iron Age . Some were used in the post- Roman period. The fortification usually follows the contours of a hill and consists of one or more lines of earthworks or stone ramparts , with stockades or defensive walls , and external ditches. If enemies were approaching,

A stela and a statuette of the Egyptian pharaohs Senusret III and Amenemhet III have also been found. However, it is unclear when they first arrived at Ugarit. In the Amarna letters , messages from Ugarit c. 1350 BC written by Ammittamru I , Niqmaddu II , and his queen have been discovered. From
465-485: A castro is a fortified pre- Roman Iron Age village, usually located on a hill or some naturally easy defendable place. The larger hillforts are also called citanias , cividades or cidás (English: cities ). They were located on hilltops, which allowed tactical control over the surrounding countryside and provided natural defences. They usually had access to a spring or small creek to provide water; some even had large reservoirs to use during sieges . Typically,

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
775-618: A "dark period" in ancient Egyptian history, spanned about 100 years after the end of the Old Kingdom from about 2181 to 2055 BC. Very little monumental evidence survives from this period, especially from the early part of it. The First Intermediate Period was a dynamic time when the rule of Egypt was roughly divided between two areas: Heracleopolis in Lower Egypt and Thebes in Upper Egypt. These two kingdoms eventually came into conflict, and
930-560: A 3rd-millennium BC culture postulated based on a collection of artefacts confiscated in 2001. In modern scholarship, the chronology of the Bronze Age Levant is divided into: The term Neo-Syria is used to designate the early Iron Age . The old Syrian period was dominated by the Eblaite first kingdom , Nagar and the Mariote second kingdom . The Akkadians conquered large areas of
1085-453: A castro had one to five stone and earth walls, which complemented the natural defences of the hill. The buildings inside, most of them circular in shape, some rectangular, were about 3.5–15 m (11–49 ft) long; they were made out of stone with thatch roofs resting on a wood column in the centre of the building. In the major oppida there were regular streets, suggesting some form of central organization. Castros vary in area from less than
1240-447: A common list of castles, fortresses, forts, an hillforts. The Latvian word for hillfort is pilskalns (plural: pilskalni ), from pils (castle) and kalns (hill). Hillforts in Latvia offered not only military and administrative functions but they were also cultural and economic centres of some regions. Latvian hillforts generally were a part of a complex consisting of
1395-512: 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
1550-889: A hectare to some 50 hectare ones, and most were abandoned after the Roman conquest of the territory. Many castros were already established during the Atlantic Bronze Age period, pre-dating the Hallstatt culture . Many of the megaliths from the Bronze Age such as menhirs and dolmens , which are frequently located near the castros, also pre-date the Celts in Portugal, Asturias and Galicia as well as in Atlantic France, Britain and Ireland. These megaliths were probably reused in syncretic rituals by
1705-498: A military reaction to social tensions caused by an increasing population and consequent pressure on agriculture. The dominant view, since the 1960s, has been that the increasing use of iron led to social changes in Britain. Deposits of iron ore were located in different places to the tin and copper ore necessary to make bronze and, as a result, trading patterns shifted and the old elites lost their economic and social status. Power passed into

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
2015-402: A permanence not enjoyed by manuscripts. These inscriptions can commonly be subdivided into four parts: a reference to the date and place, the naming of the event commemorated, the list of gifts given to the artisan in exchange for the bronze, and a dedication. The relative points of reference these vessels provide have enabled historians to place most of the vessels within a certain time frame of
2170-562: A power vacuum in Mesopotamia. At its beginning, Mitanni's major rival was Egypt under the Thutmosids . However, with the ascent of the Hittite empire, Mitanni and Egypt allied to protect their mutual interests from the threat of Hittite domination. At the height of its power during the 14th century BC, Mitanni had outposts centred on its capital, Washukanni , which archaeologists have located on
2325-448: A range of purposes and were variously tribal centres, defended places, foci of ritual activity, and places of production. Hillforts were frequently occupied by conquering armies, but on other occasions the forts were destroyed, the local people forcibly evicted, and the forts left derelict. For example, Solsbury Hill was sacked and deserted during the Belgic invasions of southern Britain in
2480-914: A refuge against attacking enemies. Ijang were first described by the English freebooter Captain William Dampier when he visited the island of Ivuhos in 1687. During the Spanish colonial era , ijang were abandoned during the Reducciones as the Ivatan population were moved into centralized towns in the lowlands. Among the Māori people , villages called pā were often built on raised ground, like volcanic hills, headlands, and small islands (including artificial islands ). The slopes were terraced into defensive ramparts that were usually further protected by palisades . Traditional pā took
2635-579: 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
2790-400: A series of straight lines creating the central fortified area that gives this style of fortification its name. Bronze Age The Bronze Age ( c. 3300 – c. 1200 BC ) was a historical period characterised principally by the use of bronze tools and the development of complex urban societies, as well as the adoption of writing in some areas. The Bronze Age
2945-472: A small administrative town) appears on a tablet from the reign of Sargon of Akkad in the 23rd century BC. The Amorite dynasty established the city-state of Babylon in the 19th century BC. Over a century later, it briefly took over the other city-states and formed the short-lived First Babylonian Empire during what is also called the Old Babylonian Period . Akkad, Assyria, and Babylonia used
3100-471: A stone wall or earthen rampart or both. These would have been important tribal centres where the chief or king of the area would live with his extended family and support themselves by farming and renting cattle to their underlings. There are around 40 known hillforts in Ireland. About 12 are multivallate as distinguished by multiple ramparts, or a large counterscarp (outer bank). The imposing example at Mooghaun
3255-624: A variety of designs, ranging from a simple terraced hill, to complex fortified structures that include multiple rows of palisades and underground defensive and ambush points. Māori pā differed from European hillforts in that they also prominently incorporate food storage pits and often, water sources. They survived until the colonial era and later types of pā were designed specifically for fighting with guns. 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

#17330848652083410-905: Is linnamägi (plural linnamäed ), meaning hillfort or hillburgh . There are several hundred hillforts or presumed ancient hillfort sites all over Estonia. Some of them, like Toompea in Tallinn or Toomemägi in Tartu, are governance centres used since ancient times up until today. Some others, like Varbola are historical sites nowadays. Most likely the Estonian hillforts were in pre-Christian times administrative, economic and military centres of Estonian tribes . Although some of them were probably used only during times of crisis and stood empty in peacetime (for example Soontagana in Koonga parish, Pärnu county ). List of Estonian fortresses [ et ] contains
3565-549: 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
3720-567: Is an argument to be made that the Bronze Age never properly ended in China, as there is no recognisable transition to an Iron Age. Together with the jade art that precedes it, bronze was seen as a fine material for ritual art when compared with iron or stone. Bronze metallurgy in China originated in what is referred to as the Erlitou period, which some historians argue places it within the Shang. Others believe
3875-428: 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
4030-565: Is called the Bactria–Margiana Archaeological Complex . The Kulli culture , similar to that of the Indus Valley Civilisation , was located in southern Balochistan (Gedrosia) c. 2500–2000 BC . The economy was agricultural. Dams were found in several places, providing evidence for a highly developed water management system. Konar Sandal is associated with the hypothesized Jiroft culture ,

Arzawa , in Western Anatolia, during the second half of the 2nd millennium BC, likely extended along southern Anatolia in a belt from near the Turkish Lakes region to the Aegean coast. Arzawa
4340-529: Is debated among scholars. An ancient civilisation is deemed to be part of the Bronze Age if it either produced bronze by smelting its own copper and alloying it with tin , arsenic , or other metals, or traded other items for bronze from producing areas elsewhere. Bronze Age cultures were the first to develop writing . According to archaeological evidence, cultures in Mesopotamia , which used cuneiform script, and Egypt , which used hieroglyphs , developed
4495-400: Is defended by multiple stone walls. One must be careful to not confuse a hill-fort with a ' ringfort '—a medieval settlement—a common archaeological feature across the whole island of Ireland, of which over 40,000 examples are known; one source claims there may be 10,000 undiscovered ringforts. In Galicia , Asturias , Cantabria , Basque Country , province of Ávila and Northern Portugal
4650-543: 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
4805-519: 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

Conceived as a global era, the Bronze Age follows the Neolithic , with a transition period between the two known as the Chalcolithic . The final decades of the Bronze Age in the Mediterranean basin are often characterised as a period of widespread societal collapse known as the Late Bronze Age collapse ( c. 1200 – c. 1150 BC ), although its severity and scope

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
5735-606: The Bronze Age in the 1st millennium BC. The earliest examples in present-day Lithuania are found in the east of the country. Most of these forts were built or expanded between the fifth and fifteenth centuries, when they were used in the Dukes' Wars, and against the invasion of Teutonic Knights from the west. Most forts were located on the banks of a river, or a confluence where two rivers met. These fortifications were typically wooden, although some had additional stone or brick walls. The hill

These were terraced into defensive ramparts with limited access points. Artifacts recovered from an ijang on the town of Savidug in Sabtang has been dated to around 1200 CE. These high rocky formations served as

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

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)
6975-433: 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

One was to protect Vilnius , the capital, and the other line in Samogitia , was a major target for both orders. This territory separated the two Orders and prevented joint action between them and Pagan Lithuania. As of 2017, according to the Atlas of Lithuanian Hillforts , there were 921 objects in Lithuania identified as piliakalniai .

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
7750-427: The Tang dynasty (618–907 AD). 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 ,
7905-419: The Theodosian Walls of Constantinople , together with partial remains elsewhere. These are mostly city gates, like the Porta Nigra in Trier or Newport Arch in Lincoln . 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.

Founded by an Indo-Aryan ruling class that governed a predominantly Hurrian population, Mitanni came to be a regional power after the Hittite destruction of Kassite Babylon created
8525-530: 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
8680-436: The 1st century BC. Abandoned forts were sometimes reoccupied and refortified under renewed threat of foreign invasion, such as the Dukes' Wars in Lithuania , and the successive invasions of Britain by Romans , Saxons and Vikings . Celtic hillforts developed in the Late Bronze and Early Iron Age, roughly the start of the first millennium BC , and were used in many Celtic areas of central and western Europe until
8835-430: The 3rd millennium BC. The Bronze Age is characterised by the widespread use of bronze , though the introduction and development of bronze technology were not universally synchronous. Tin bronze technology requires systematic techniques: tin must be mined (mainly as the tin ore cassiterite ) and smelted separately, then added to hot copper to make bronze alloy. The Bronze Age was a time of extensive use of metals and

During the 10th–11th centuries, some of the hillforts became military fortresses with strong fortifications (like hillforts in Tērvete , Talsi , Mežotne ). Some of them are considered important political centres of the local peoples, who in this period were subjects of serious social political changes. That period

White argues that iron did not supplant bronze "at any period before the end of the Zhou dynasty (256 BC)" and that bronze vessels make up the majority of metal vessels through the Eastern Han period , or to 221 BC. The Chinese bronze artefacts generally are either utilitarian, like spear points or adze heads, or "ritual bronzes" , which are more elaborate versions in precious materials of everyday vessels, as well as tools and weapons.

With the emergence of oppida in the Late Iron Age, settlements could reach as large as 10,000 inhabitants. As the population increased so did the complexity of prehistoric societies. Around 1100 BC hillforts emerged and in the following centuries spread through Europe. They served

They are most common during later periods: The Hallstatt culture and La Tène culture originated in what is now southern Germany, Switzerland, Austria, Slovakia and the Czech Republic. The predominant form of rampart construction was pfostenschlitzmauer , or Kelheim-style . During the Hallstatt ;C period, hillforts became the dominant settlement type in the west of Hungary. Julius Caesar described
11780-784: The Second Intermediate Period in control of Avaris and the Nile Delta . By the Fifteenth Dynasty, they ruled lower Egypt. They were expelled at the end of the Seventeenth Dynasty . The New Kingdom of Egypt , also referred to as the Egyptian Empire, existed during the 16th–11th centuries BC. The New Kingdom followed the Second Intermediate Period and was succeeded by the Third Intermediate Period . It
11935-731: The Theban kings conquered the north, reunifying Egypt under a single ruler during the second part of the Eleventh Dynasty . The Bronze Age in Nubia started as early as 2300 BC. Egyptians introduced copper smelting to the Nubian city of Meroë in present-day Sudan c. 2600 BC . A furnace for bronze casting found in Kerma has been dated to 2300–1900 BC. The Middle Kingdom of Egypt spanned between 2055 and 1650 BC. During this period,
12090-609: The Western Zhou period, allowing them to trace the evolution of the vessels and the events they record. The Japanese archipelago saw the introduction of bronze during the early Yayoi period ( c. 300 BC ), which saw the introduction of metalworking and agricultural practices brought by settlers arriving from the continent. Bronze and iron smelting spread to the Japanese archipelago through contact with other ancient East Asian civilisations, particularly immigration and trade from
12245-445: The ancient Korean peninsula, and ancient mainland China. Iron was mainly used for agricultural and other tools, whereas ritual and ceremonial artefacts were mainly made of bronze. On the Korean Peninsula, the Bronze Age began c. 1000–800 BC . Initially centred around Liaoning and southern Manchuria, Korean Bronze Age culture exhibits unique typology and styles, especially in ritual objects. The Mumun pottery period
12400-508: 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
12555-410: 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
12710-654: The beginning of the Old Kingdom . With the First Dynasty, the capital moved from Abydos to Memphis with a unified Egypt ruled by an Egyptian god-king. Abydos remained the major holy land in the south. The hallmarks of ancient Egyptian civilisation, such as art, architecture and religion, took shape in the Early Dynastic Period. Memphis , in the Early Bronze Age, was the largest city of the time. The Old Kingdom of
12865-516: The civilians would spot them from a distance. Prehistoric Europe saw a growing population. It has been estimated that in about 5000 BC during the Neolithic between 2 million and 5 million lived in Europe; in the Late Iron Age it had an estimated population of around 15 to 30 million. Outside Greece and Italy , which were more densely populated, the vast majority of settlements in
13020-560: 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
13175-407: 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
13330-931: 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
13485-485: 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
13640-525: The development of trade networks. A 2013 report suggests that the earliest tin-alloy bronze was a foil dated to the mid-5th millennium BC from a Vinča culture site in Pločnik , Serbia , although this culture is not conventionally considered part of the Bronze Age; however, the dating of the foil has been disputed. West Asia and the Near East were the first regions to enter the Bronze Age, beginning with
13795-706: The discovery of the Europoid Tarim mummies in Xinjiang has caused some archaeologists such as Johan Gunnar Andersson , Jan Romgard, and An Zhimin to suggest a possible route of transmission from the West eastwards. According to An Zhimin, "It can be imagined that initially, bronze and iron technology took its rise in West Asia, first influenced the Xinjiang region, and then reached the Yellow River valley, providing external impetus for
13950-416: The earliest practical writing systems. Bronze Age civilisations gained a technological advantage due to bronze's harder and more durable properties than other metals available at the time. While terrestrial iron is naturally abundant, the higher temperature required for smelting, 1,250 °C (2,280 °F), in addition to the greater difficulty of working with it, placed it out of reach of common use until
14105-701: The element sten / stein were usually hillforts. In Sweden, there are 1,100 known hillforts with a strong concentration on the northern west coast and in eastern Svealand . In Södermanland there are 300, in Uppland 150, Östergötland 130, and 90 to 100 in each of Bohuslän and Gotland . Norway has about 400 hillforts. Denmark has 26 hillforts. The Finnish word for hillfort is linnavuori (plural linnavuoret ), meaning fort hill or castle hill , or alternatively muinaislinna meaning ancient fort , as opposed to bare linna which refers to medieval or later fortifications. One special feature about
14260-458: The end of the 2nd millennium BC. Tin's lower melting point of 232 °C (450 °F) and copper's moderate melting point of 1,085 °C (1,985 °F) placed both these metals within the capabilities of Neolithic pottery kilns , which date to 6000 BC and were able to produce temperatures of at least 900 °C (1,650 °F). Copper and tin ores are rare since there were no tin bronzes in West Asia before trading in bronze began in
14415-609: 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
14570-580: The excavator to implicate the Cadbury population in a revolt in the 70's AD (roughly contemporary with that of Boudicca in the East of England), although this has been questioned by subsequent researchers. However, the presence of barracks on the hilltop in the decades following the conquest suggest an ongoing struggle to suppress local dissent. Maiden Castle in Dorset is the largest hillfort in England. Where Roman influence
14725-633: The fall of the monarchy. The name "Israel" first appears c. 1209 BC , at the end of the Late Bronze Age and the very beginning of the Iron Age, on the Merneptah Stele raised by the Egyptian pharaoh Merneptah . The Arameans were a Northwest Semitic semi-nomadic pastoral people who originated in what is now modern Syria (Biblical Aram ) during the Late Bronze and early Iron Age. Large groups migrated to Mesopotamia, where they intermingled with
14880-400: 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
15035-400: The flooded river has washed out the base of the hill. Now around 80 percent of piliakalniai are covered by forests and are hardly accessible to visitors. In Russia , Belarus and Poland Iron Age and Early Medieval hillforts are called gords . They were the residence of local rulers, and provided for refuge in times of war. Similar structures can be found elsewhere in the world, such as
15190-467: 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
15345-521: 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
15500-504: 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
15655-510: The hands of a new group of people. Archaeologist Barry Cunliffe believes that population increase still played a role and has stated "[the forts] provided defensive possibilities for the community at those times when the stress [of an increasing population] burst out into open warfare. But I wouldn't see them as having been built because there was a state of war. They would be functional as defensive strongholds when there were tensions and undoubtedly some of them were attacked and destroyed, but this
15810-656: The headwaters of the Khabur River . Eventually, Mitanni succumbed to the Hittites and later Assyrian attacks, eventually being reduced to a province of the Middle Assyrian Empire . The Israelites were an ancient Semitic-speaking people of the Ancient Near East who inhabited part of Canaan during the tribal and monarchic periods (15th–6th centuries BC), and lived in the region in smaller numbers after
15965-518: 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,
16120-413: 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
16275-402: 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,
16430-507: The large late Iron Age hillforts he encountered during his campaigns in Gaul as oppida . By this time the larger ones had become more like cities than fortresses and many were assimilated as Roman towns. The reason for the emergence of hillforts in Britain, and their purpose, has been a subject of debate. It has been argued that they could have been military sites constructed in response to invasion from continental Europe, sites built by invaders, or
16585-413: 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
16740-474: The largest amongst forts reoccupied following the end of Roman rule , to defend against pirate raids, and the Anglo-Saxon invasions. The cemetery outside Poundbury Hill contains east-facing Christian burials of the 4th century CE. In Wales, the hillfort at Dinas Powys was a late Iron Age hillfort reoccupied from the 5th-6th centuries CE; similarly at Castell Dinas Brân a hillfort of c. 600 BCE
16895-476: 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
17050-579: The main fortress, the settlement around it, one or more burial fields and nearby ritual sites. The first hillforts in Latvia, such as Daugmale hillfort, appeared during the Bronze Age . Some were continuously inhabited until the late Iron Age . During the Roman Iron Age, some of the Latvian hillforts (like Ķivutkalns ) were abandoned or became sparsely populated. A new period in hillfort development started during
17205-545: The native Akkadian (Assyrian and Babylonian) population. The Aramaeans never had a unified empire; they were divided into independent kingdoms all across the Near East. After the Bronze Age collapse, their political influence was confined to Syro-Hittite states, which were entirely absorbed into the Neo-Assyrian Empire by the 8th century BC. The Mesopotamian Bronze Age began c. 3500 BC and ended with
17360-408: The numerous large sacrificial tripods known as dings ; there are many other distinct shapes. Surviving identified Chinese ritual bronzes tend to be highly decorated, often with the taotie motif, which involves stylised animal faces. These appear in three main motif types: those of demons, symbolic animals, and abstract symbols. Many large bronzes also bear cast inscriptions that are the bulk of
17515-525: 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
17670-440: 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
17825-688: The origins of agriculture. Foothill regions and glacial melt streams supported Bronze Age agro-pastoralists who developed complex east–west trade routes between Central Asia and China that introduced wheat and barley to China and millet to Central Asia. The Bactria–Margiana Archaeological Complex (BMAC), also known as the Oxus civilisation, was a Bronze Age civilisation in Central Asia, dated c. 2400 – c. 1600 BC , located in present-day northern Afghanistan , eastern Turkmenistan , southern Uzbekistan and western Tajikistan , centred on
17980-711: 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
18135-576: The point of origin of a cultural enigma termed the Seima-Turbino Phenomenon . It is conjectured that changes in climate in this region c. 2000 BC , and the ensuing ecological, economic, and political changes, triggered a rapid and massive migration westward into northeast Europe, eastward into China, and southward into Vietnam and Thailand across a frontier of some 4,000 mi (6,000 km). This migration took place in just five to six generations and led to peoples from Finland in
18290-409: 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
18445-471: 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
18600-521: The region laid the foundations for astronomy , mathematics, and astrology . The following dates are approximate. The Bronze Age in the Near East can be divided into Early, Middle and Late periods. The dates and phases below apply solely to the Near East, not universally. However, some archaeologists propose a "high chronology", which extends periods such as the Intermediate Bronze Age by 300 to 500–600 years, based on material analysis of
18755-466: The regional Bronze Age is the name given to the period in the 3rd millennium BC when Egyptian civilisation attained its first continuous peak of complexity and achievement—the first of three "Kingdom" periods which marked the high points of civilisation in the lower Nile Valley (the others being the Middle Kingdom and New Kingdom ). The First Intermediate Period of Egypt , often described as
18910-576: 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
19065-429: 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
19220-648: The rise of the Mesopotamian civilisation of Sumer in the mid-4th millennium BC. Cultures in the ancient Near East practised intensive year-round agriculture; developed writing systems ; invented the potter's wheel , created centralised governments (usually in the form of hereditary monarchies ), formulated written law codes, developed city-states , nation-states and empires; embarked on advanced architectural projects; and introduced social stratification , economic and civil administration, slavery , and practised organised warfare, medicine, and religion. Societies in
19375-530: The rise of the Shang and Zhou civilizations." According to Jan Romgard, "bronze and iron tools seem to have traveled from west to east as well as the use of wheeled wagons and the domestication of the horse." There are also possible links to Seima-Turbino culture , "a transcultural complex across northern Eurasia", the Eurasian steppe, and the Urals. However, the oldest bronze objects found in China so far were discovered at
19530-682: The socket, which could be associated with the Seima-Turbino visual vocabulary of southern Siberia. The metallurgical centres of northwestern China, especially the Qijia culture in Gansu and Longshan culture in Shaanxi , played an intermediary role in this process. Iron use in China dates as early as the Zhou dynasty ( c. 1046 – 256 BC), but remained minimal. Chinese literature authored during
19685-448: The southern Korean Peninsula gradually adopted bronze production ( c. 700–600 BC ) after a period when Liaoning-style bronze daggers and other bronze artefacts were exchanged as far as the interior part of the Southern Peninsula ( c. 900–700 BC ). The bronze daggers lent prestige and authority to the personages who wielded and were buried with them in high-status megalithic burials at south-coastal centres such as
19840-435: 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
19995-438: 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
20150-525: 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
20305-489: The support of pales. They often have well delineated gateways, the gates of which were probably of wood. Hillforts with strong walls are often located beside old trade routes and have an offensive character, whereas others are reclusive and were weakly fortified, probably only for hiding during raids. Many forts, located centrally in densely populated areas, were permanently settled strongholds and can show traces of settlements both inside and outside. Older place names containing
20460-413: The surviving body of early Chinese writing and have helped historians and archaeologists piece together the history of China, especially during the Zhou dynasty. The bronzes of the Western Zhou document large portions of history not found in the extant texts that were often composed by persons of varying rank and possibly even social class. Further, the medium of cast bronze lends the record they preserve
20615-426: The term embraces a wide range of very different settlements in high locations. At least a few of the Germanic settlements were protected by fortifications. Unlike the Romans, however, the Germanii did not use mortar at that time for their construction. Among the best known hill settlements in Germany are the Runder Berg near Bad Urach and the Gelbe Bürg near Dittenheim. In Sweden, hillforts are fortifications from
20770-405: 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
20925-410: The upper Amu Darya (Oxus River). Its sites were discovered and named by the Soviet archaeologist Viktor Sarianidi (1976). Bactria was the Greek name for the area of Bactra (modern Balkh ), in what is now northern Afghanistan, and Margiana was the Greek name for the Persian satrapy of Marguš , the capital of which was Merv in present-day Turkmenistan. A wealth of information indicates that
21080-499: 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
21235-559: 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
21390-403: The west to Thailand in the east employing the same metalworking technology and, in some areas, horse breeding and riding. However, recent genetic testings of sites in south Siberia and Kazakhstan ( Andronovo horizon) would rather support spreading of the bronze technology via Indo-European migrations eastwards, as this technology had been well known for quite a while in western regions. It
21545-410: 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
21700-572: 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
21855-424: The written East Semitic Akkadian language for official use and as a spoken language. By that time, the Sumerian language was no longer spoken, but was still in religious use in Assyria and Babylonia, and would remain so until the 1st century AD. The Akkadian and Sumerian traditions played a major role in later Assyrian and Babylonian culture. Despite this, Babylonia, unlike the more militarily powerful Assyria,
22010-399: Was Egypt's most prosperous time and marked the peak of Egypt's power. The later New Kingdom, comprising the Nineteenth and Twentieth dynasties (1292–1069 BC), is also known as the Ramesside period , after the eleven pharaohs who took the name of Ramesses. Elam was a pre-Iranian ancient civilisation located east of Mesopotamia. In the Middle Bronze Age, Elam consisted of kingdoms on
22165-430: 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
22320-812: Was a new linear earthwork connected to the existing hillfort at Maes Knoll , which defined the Celtic-Saxon border in south-west England during the period 577–652 CE. Some hillforts were re-occupied by the Anglo-Saxons during the period of Viking raids. King Alfred established a network of coastal hillforts and lookout posts in Wessex , linked by a Herepath , or military road, which enabled his armies to cover Viking movements at sea. For example, see Daw's Castle and Battle of Cynwit . It has been suggested on reasonable evidence that many so-called hillforts were just used to pen in cattle, horses, or other domesticated animals. The large sprawling examples at Bindon Hill and Bathampton Down are more than 50 acres (20 ha ). Even those that were defensive settlements in
22475-549: 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
22630-468: 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
22785-435: 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
22940-411: Was founded by non-native Amorites and often ruled by other non-indigenous peoples such as the Kassites , Aramaeans and Chaldeans , as well as by its Assyrian neighbours. For many decades, scholars made superficial reference to Central Asia as the "pastoral realm" or alternatively, the "nomadic world", in what researchers call the "Central Asian void": a 5,000-year span that was neglected in studies of
23095-497: Was known for unrest and military activities, as well as power struggles between local aristocracy. Most of the Latvian hillforts were destroyed or abandoned during the Livonian Crusade in the 13th century, but some were still used in the 14th century.
