122-692: Fort Conrad was a U.S. Army fort established in Socorro County , New Mexico Territory in 1851. Fort Conrad was located near modern Tiffany, New Mexico. It was on the west side of the Rio Grande . Because of its location, it was later abandoned for Fort Craig in 1854. This New Mexico state location article is a stub . You can help Misplaced Pages by expanding it . Fort 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

244-402: A buccinator . Ordinary camp life began with a buccina call at daybreak, the first watch of the day. The soldiers arose at this time and shortly after gathered in the company area for breakfast and assembly. The centurions were up before them and off to the principia where they and the equites were required to assemble. The regimental commanders, the tribunes, were already converging on

366-430: 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

488-511: A Roman camp, for example Marsala in Sicily, the ancient Lilybaeum, where the name of the main street, the Cassaro, perpetuates the name "castrum". The castrum's special structure also defended from attacks. The base ( munimentum , "fortification") was placed entirely within the vallum ("wall"), which could be constructed under the protection of the legion in battle formation if necessary. The vallum

610-516: A building or plot of land, used as a fortified military base . In English usage, castrum commonly translates to "Roman fort", "Roman camp" and "Roman fortress". However, scholastic convention tends to translate castrum as "fort", "camp", "marching camp" or "fortress". Romans used the term castrum for different sizes of camps – including large legionary fortresses, smaller forts for cohorts or for auxiliary forces, temporary encampments , and "marching" forts. The diminutive form castellum

732-415: A camp had both public and private latrines . A public latrine consisted of a bank of seats situated over a channel of running water. One of the major considerations for selecting the site of a camp was the presence of running water, which the engineers diverted into the sanitary channels. Drinking water came from wells; however, the larger and more permanent bases featured the aqueduct , a structure running

854-512: 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

976-405: A few hours. Judging from the names, they probably used a repertory of camp plans, selecting the one appropriate to the length of time a legion would spend in it: tertia castra , quarta castra , etc. ( a camp of three days , four days , etc.). More permanent camps were castra stativa ( standing camps ). The least permanent of these were castra aestiva or aestivalia , "summer camps", in which

1098-531: A general staff officer, who might manage training at several camps. According to Vegetius, the men might take a 32 kilometres (20 mi) hike or a 68 kilometres (42 mi) jog under full pack, or swim a river. Marching drill was always in order. Each soldier was taught the use of every weapon and also was taught to ride. Seamanship was taught at naval bases. Soldiers were generalists in the military and construction arts. They practiced archery, spear-throwing and above all swordsmanship against posts ( pali ) fixed in

1220-457: A modern study shows that the intervallum "was 1/16th of the square root of the area it enclosed in the fort." Legionaries were quartered in a peripheral zone inside the intervallum , which they could rapidly cross to take up position on the vallum . Inside of the legionary quarters was a peripheral road, the Via Sagularis , probably a type of "service road", as the sagum , a kind of cloak,

1342-413: 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

1464-579: 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

1586-628: A room, who slept on bunkbeds. The soldiers in each room were also required to cook their own meals and eat with their "roommates". From the time of Augustus more permanent castra with wooden or stone buildings and walls were introduced as the distant and hard-won boundaries of the expanding empire required permanent garrisons to control local and external threats from warlike tribes. Previously, legions were raised for specific military campaigns and subsequently disbanded, requiring only temporary castra. From then on many castra of various sizes were established, many of which became permanent settlements. From

1708-633: A series of straight lines creating the central fortified area that gives this style of fortification its name. Castra In the Roman Republic and the Roman Empire , the Latin word castrum ( pl. : castra ) was a military-related term. In Latin usage, the singular form castrum meant ' fort ', while the plural form castra meant 'camp'. The singular and plural forms could refer in Latin to either

1830-400: A stockade, for which the soldiers carried stakes, and a ditch. The castra could be prepared under attack within a hollow square or behind a battle line. Considering that the earliest military shelters were tents made of hide or cloth, and all but the most permanent bases housed the men in tents placed in quadrangles and separated by numbered streets, one castrum may well have acquired

1952-517: A stream captured from high ground (sometimes miles away) into the camp. The praetorium had its own latrine and probably the quarters of the high-ranking officers. In or near the intervallum , where they could easily be accessed, were the latrines of the soldiers. A public bathhouse for the soldiers, also containing a latrine, was located near or on the Via Principalis . The influence of a base extended far beyond its walls. The total land required for

2074-512: Is De Munitionibus Castrorum , a manuscript of 11 pages that dates most probably from the late 1st to early 2nd century AD. Regulations required a major unit in the field to retire to a properly constructed camp every day. "… as soon as they have marched into an enemy's land, they do not begin to fight until they have walled their camp about; nor is the fence they raise rashly made, or uneven; nor do they all abide ill it, nor do those that are in it take their places at random; but if it happens that

2196-462: Is a change of meaning from the reflexes in other languages, which still mean some sort of knife, axe, or spear. Pokorny explains it as 'Lager' als 'abgeschnittenes Stück Land' , "a lager, as a cut-off piece of land"> If this is the civilian interpretation, the military version must be "military reservation", a piece of land cut off from the common land around it and modified for military use. All castra must be defended by works, often no more than

2318-549: 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

2440-428: 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

2562-409: Is archaeological evidence in one case of an indoor equestrian ring. Apart from the training, each soldier had a regular job on the base, of which there was a large variety from the various kinds of clerk to the craftsmen. Soldiers changed jobs frequently. The commander's policy was to have all the soldiers skilled in all the arts and crafts so that they could be as interchangeable as possible. Even then

2684-543: 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

2806-519: 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

2928-399: The buccina or bucina , the cornu and the tuba . As they did not possess valves for regulating the pitch, the range of these instruments was somewhat limited. Nevertheless, the musicians ( aenatores , "brassmen") managed to define enough signals for issuing commands. The instrument used to mark the passage of a watch was the buccina , from which the trumpet derives. It was sounded by

3050-629: The Balkans , either by itself or in various compounds such as the World Heritage Site of Gjirokastër (earlier Argurokastro ). The terms stratopedon ( army camp ) and phrourion ( fortification ) were used by Greek language authors to translate castrum and castellum , respectively. A castrum was designed to house and protect the soldiers, their equipment and supplies when they were not fighting or marching. The most detailed description that survives about Roman military camps

3172-732: The British Raj are found in the mainland Indian subcontinent (modern day India , Pakistan , Bangladesh and Nepal ). "Fort" is the word used in India for all old fortifications. 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

3294-614: The Indus Valley Civilization were the first small cities to be fortified. 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

3416-1147: 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

3538-574: 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)

3660-552: 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

3782-518: The Nordic states and in Britain , the fortifications of Berwick-upon-Tweed and the harbour archipelago of Suomenlinna at Helsinki being fine examples. During the 18th century, it was found that the continuous enceinte , or main defensive enclosure of a bastion fortress, could not be made large enough to accommodate the enormous field armies which were increasingly being employed in Europe; neither could

3904-677: The Old City of Shanghai , Suzhou , Xi'an and the walled villages of Hong Kong . 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 ,

4026-553: The Principia contained the Quaestorium . By the late empire it had developed also into a safekeep for plunder and a prison for hostages and high-ranking enemy captives. Near the Quaestorium were the quarters of the headquarters guard ( Statores ), who amounted to two centuries (companies). If the Imperator was present they served as his bodyguard. Further from the Quaestorium were

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

4270-617: 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 ,

4392-733: 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. A number of forts dating from the Later Stone Age to

4514-522: The Via Praetoria offered another division of the camp into four quarters. Across the central plaza ( principia ) to the east or west was the main gate, the Porta Praetoria . Marching through it and down "headquarters street" a unit ended up in formation in front of the headquarters. The standards of the legion were located on display there, very much like the flag of modern camps. On the other side of

4636-447: The Via Principalis were the homes or tents of the several tribunes in front of the barracks of the units they commanded. The central region of the Via Principalis with the buildings for the command staff was called the Principia (plural of principium ). It was actually a square, as across this at right angles to the Via Principalis was the Via Praetoria , so called because the praetorium interrupted it. The Via Principalis and

Castrorum Filius , "son of the camps", was one of the names used by the emperor Caligula and then also by other emperors. Castro , also derived from Castrum , is a common Spanish family name as well as toponym in Spain and other Hispanophone countries, Italy , and

4880-597: The latera ("sides") were the Arae (sacrificial altars), the Auguratorium (for auspices ), the Tribunal , where courts martial and arbitrations were conducted (it had a raised platform), the guardhouse, the quarters of various kinds of staff and the storehouses for grain ( horrea ) or meat ( carnarea ). Sometimes the horrea were located near the barracks and the meat was stored on the hoof. Analysis of sewage from latrines indicates

5002-503: The medici ordinarii , had to be qualified physicians. They were allowed medical students, practitioners and whatever orderlies they needed; i.e., the military hospitals were medical schools and places of residency as well. Officers were allowed to marry and to reside with their families on base. The army did not extend the same privileges to the men, who were not allowed to marry. However, they often kept common law families off base in communities nearby. The communities might be native, as

5124-454: The praetorium . There the general staff planned the day. At a staff meeting the tribunes received the password and the orders of the day. They brought those back to the centuriones , who returned to their company areas to instruct the men. For soldiers, the main agendum was a vigorous training session lasting about a watch long. Recruits received two, one in the morning and one in the afternoon. Planning and supervision of training were under

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

5368-530: 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

5490-577: 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

5612-621: 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

5734-461: The aisle), ten men per tent. Ideally a company took 10 tents, arranged in a line of 10 companies, with the 10th near the Porta Decumana . Of the c. 9.2 square metres of bunk space each man received 0.9, or about 0.6 by 1.5 m, which was only practical if they slept with heads to the aisle. The single tent with its men was called contubernium , also used for "squad". A squad during some periods

5856-508: 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

5978-403: The arms at one end and the common area at the other. The company area was used for cooking and recreation such as gaming. The army provisioned the men and had their bread ( panis militaris ) baked in outdoor ovens, but the men were responsible for cooking and serving themselves. They could buy meals or supplementary foods at the canteen. The officers were allowed servants. For sanitary facilities,

6100-410: 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

6222-434: The aspect ratio of the castra one could determine the order of battle, and the size of the legion it housed determined the area of the camp. Steinhoff theorizes that Richardson has identified a commonality and builds on the latter's detailed studies to suggest that North African encampments in the time of Hadrian were based on the same geometrical skill. The street plans of various present-day cities still retain traces of

6344-495: The basic plan is the same. The hypothesis of an Etruscan origin is a viable alternative. The ideal enforced a linear plan for a camp or fort: a square for camps to contain one legion or smaller unit, a rectangle for two legions, each legion being placed back-to-back with headquarters next to each other. The religious devotion of the Romans to geometry caused them to build into their camps whole-numbered right triangles. Laying it out

6466-400: The camp was placed to best advantage on a hill or slope near the river, the naval base was usually outside its walls. The classici and the optiones of the naval installation relied on the camp for its permanent defense. Naval personnel generally enjoyed better quarters and facilities. Many were civilians working for the military. The ideal plan was typically modified to suit the terrain and

6588-411: The circumstances. Each camp discovered by archaeology has its own specific layout and architectural features, which makes sense from a military point of view. If, for example, the camp was built on an outcrop, it followed the lines of the outcrop. The terrain for which it was best suited and for which it was probably designed in distant prehistoric times was the rolling plain. The camp was best placed on

6710-401: The connotation of tent. The commonest Latin syntagmata (here phrases) for the term castra are: In Latin the term castrum is much more frequently used as a proper name for geographical locations: e.g., Castrum Album , Castrum Inui , Castrum Novum , Castrum Truentinum , Castrum Vergium . The plural was also used as a place name, as Castra Cornelia , and from this comes

6832-560: 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

6954-407: 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

7076-931: 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

7198-485: 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

7320-439: The ditch served also as a moat . A legion-sized camp placed towers at intervals along the wall with positions between for the division artillery. Around the inside periphery of the vallum was a clear space, the intervallum , which served to catch enemy missiles, as an access route to the vallum and as a storage space for cattle ( capita ) and plunder ( praeda ). The Romans were masters of geometry and showed it in their camps:

7442-704: 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

7564-400: 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

7686-457: The field. Neither the Celtic nor Germanic armies had this capability: they found it necessary to disperse after only a few days. Camps were the responsibility of engineering units to which specialists of many types belonged, officered by architecti , "chief engineers", who requisitioned manual labor from the soldiers at large as required. A unit could throw up a camp under enemy attack in as little as

7808-632: The fifth). If the camp needed more gates, one or two of the Porta Quintana were built, presumably named dextra and sinistra . If the gates were not built, the Porta Decumana also became the Porta Quintana . At Via Quintana a public market was allowed. The Via Quintana and the Via Principalis divided the camp into three districts: the Latera Praetorii , the Praetentura and the Retentura . In

7930-467: 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

8052-420: The front the quarters of special forces. These included Classici ("marines", as most European camps were on rivers and contained a river naval command), Equites ("cavalry"), Exploratores ("scouts"), and Vexillarii (carriers of vexilla , the official pennants of the legion and its units). Troops who did not fit elsewhere also were there. The part of the Retentura ("stretching to the rear") closest to

8174-521: 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

8296-504: 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

8418-410: The goal was not entirely achievable. The gap was bridged by the specialists, the optiones or "chosen men", of which there were many different kinds. For example, a skilled artisan might be chosen to superintend a workshop. Soldiers were also expected to build the camp upon arrival before engaging in any sort of warfare after a day's march. The supply administration was run as a business using money as

8540-400: The ground is uneven, it is first levelled: their camp is also four-square by measure, and carpenters are ready, in great numbers, with their tools, to erect their buildings for them." To this end a marching column ported the equipment needed to build and stock the camp in a baggage train of wagons and on the backs of the soldiers. The camp allowed the Romans to keep a rested and supplied army in

8662-521: The ground. Training was taken very seriously and was democratic. Ordinary soldiers would see all the officers training with them including the praetor or the emperor if he was in camp. Swordsmanship lessons and use of the shooting range probably took place on the campus , a "field" outside the castra , from which English "camp" derives. Its surface could be lightly paved. Winter curtailed outdoor training. The general might in that case have sheds constructed, which served as field houses for training. There

8784-518: 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,

8906-413: 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

9028-426: The installation as a military facility. For example, none of the soldiers was required to man the walls all the time, but round-the-clock duty required a portion of the soldiers to be on duty at any time. Duty time was divided into vigilia , the eight watches into which the 24-hour day was divided so they stood guard for three hours that day. The Romans used signals on brass instruments to mark time. These were mainly

9150-402: 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,

9272-413: 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

9394-703: The legionary diet was mainly grain. Also located in the Latera was the Armamentarium , a long shed containing any heavy weapons and artillery not on the wall. The Praetentura ("stretching to the front") contained the Scamnum Legatorum , the quarters of officers who were below general but higher than company commanders ( Legati ). Near the Principia were the Valetudinarium (hospital), Veterinarium (for horses), Fabrica ("workshop", metals and wood), and further to

9516-476: 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

9638-476: The maintenance of a permanent base was called its territoria . In it were located all the resources of nature and the terrain required by the base: pastures, woodlots, water sources, stone quarries, mines, exercise fields and attached villages. The central castra might also support various fortified adjuncts to the main base, which were not self-sustaining as was the base. In this category were speculae , "watchtowers", castella , "small camps", and naval bases. All

9760-402: The major bases near rivers featured some sort of fortified naval installation, one side of which was formed by the river or lake. The other sides were formed by a polygonal wall and ditch constructed in the usual way, with gates and watchtowers. The main internal features were the boat sheds and the docks. When not in use, the boats were drawn up into the sheds for maintenance and protection. Since

9882-508: The medium of exchange. The aureus was the preferred coin of the late republic and early empire; in the late empire the solidus came into use. The larger bases, such as Moguntiacum , minted their own coins. As does any business, the base quaestorium required careful record keeping, performed mainly by the optiones. A chance cache of tablets from Vindolanda in Britain gives us a glimpse of some supply transactions. They record, among other things,

10004-566: The most ancient times Roman camps were constructed according to a certain ideal pattern, formally described in two main sources, the De Munitionibus Castrorum and the works of Polybius . Alan Richardson compares both original authors and concludes that "the Hyginian model greatly reduced the area and perimeter length for any given force." P. Fl. Vegetius Renatus has a small section on entrenched camps as well. The terminology varies, but

10126-527: The name Via Decumana or the entire Via Praetoria be replaced with Decumanus Maximus . In peaceful times the camp set up a marketplace with the natives in the area. They were allowed into the camp as far as the units numbered 5 (half-way to the praetorium). There another street crossed the camp at right angles to the Via Decumana , called the Via Quintana , (English: 5th street , from Latin: quintana ,

10248-420: The northern places like Britain, where it got cold in the winter, they would make wood or stone barracks. The Romans would also put a fireplace in the barracks. They had about three bunk beds in it. They had a small room beside it where they put their armour; it was as big as the tents. They would make these barracks if the fort they had was going to stay there for good. A tent was 3 by 3.5 metres (0.6 m for

10370-525: 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

10492-440: 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

10614-519: The other side was the forum , a small duplicate of an urban forum, where public business could be conducted. The Via Principalis went through the vallum in the Porta Principalis Dextra ("right principal gate") and Porta Principalis Sinistra ("left, etc."), which were gates fortified with turres ("towers"). Which was on the north and which on the south depends on whether the praetorium faced east or west, which remains unknown. Along

10736-711: 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

10858-461: The palisade. The streets, gates and buildings present depended on the requirements and resources of the camp. The gates might vary from two to six and not be centred on the sides. Not all the streets and buildings might be present. Many settlements in Europe originated as Roman military camps and still show traces of their original pattern (e.g. Castres in France , Barcelona in Spain ). The pattern

10980-409: 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

11102-520: The praetorium the Via Praetoria continued to the wall, where it went through the Porta Decumana . In theory this was the back gate. Supplies were supposed to come in through it and so it was also called, descriptively, the Porta Quaestoria . The term Decumana, "of the 10th", came from the arranging of manipuli or turmae from the first to the 10th, such that the 10th was near the intervallum on that side. The Via Praetoria on that side might take

11224-458: The purchase of consumables and raw supplies, the storage and repair of clothing and other items, and the sale of items, including foodstuffs, to achieve an income. Vindolanda traded vigorously with the surrounding natives. Another feature of the camp was the military hospital ( valetudinarium , later hospitium ). Augustus instituted the first permanent medical corps in the Roman army . Its physicians,

11346-471: 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

11468-636: 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

11590-429: 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

11712-475: The same derivation, from the diminutive castellum or "little fort", but does not usually indicate a former Roman camp. Whitley Castle however is an exception, referring to the Roman fort of Epiacum in Northumberland . Activities conducted in a castra can be divided into ordinary and "the duty" or "the watch". Ordinary activity was performed during regular working hours. The duty was associated with operating

11834-460: The same meaning, says Pokorny, as Latin fundus , an estate, or tract of land. This is not any land but is a prepared or cultivated tract, such as a farm enclosed by a fence or a wooden or stone wall of some kind. Cornelius Nepos uses Latin castrum in that sense: when Alcibiades deserts to the Persians, Pharnabazus gives him an estate ( castrum ) worth 500 talents in tax revenues. This

11956-427: The soldiers were housed sub pellibus or sub tentoriis , "under tents". The largest castra were legionary fortresses built as bases for one or more whole legions. Summer was the campaign season. For the winter the soldiers retired to castra hiberna containing barracks and other buildings of more solid materials, with timber construction gradually being replaced by stone. Castra hibernas held eight soldiers to

12078-484: 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

12200-438: 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

12322-626: 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

12444-475: The summit and along the side of a low hill, with spring water running in rivulets through the camp ( aquatio ) and pastureland to provide grazing ( pabulatio ) for the animals. In case of attack, arrows, javelins and sling missiles could be fired down at an enemy tiring himself to come up. For defence, troops could be formed in an acies , or "battle-line", outside the gates where they could be easily resupplied and replenished as well as being supported by archery from

12566-468: The tents of the Nationes ("natives"), who were auxiliaries of foreign troops, and the legionaries in double rows of tents or barracks ( Strigae ). One Striga was as long as required and 18 m wide. In it were two Hemistrigia of facing tents centered in its 9 m strip. Arms could be stacked before the tents and baggage carts kept there as well. Space on the other side of the tent was for passage. In

12688-464: The tribesmen tended to build around a permanent base for purposes of trade, but also the base sponsored villages ( vici ) of dependents and businessmen. Dependants were not allowed to follow an army on the march into hostile territory. Military service was for about 25 years. At the end of that time, the veteran was given a certificate of honorable discharge ( honesta missio ). Some of these have survived engraved on stone. Typically they certify that

12810-474: 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

12932-458: The veteran, his wife (one per veteran) and children or his sweetheart were now Roman citizens, which is a good indication that troops, which were used chiefly on the frontier, were from peoples elsewhere on the frontier who wished to earn Roman citizenship. However, under Antoninus Pius , citizenship was no longer granted to the children of rank-and-file veterans, the privilege becoming restricted only to officers. Veterans often went into business in

13054-499: 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

13176-559: 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

13298-410: 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

13420-627: 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

13542-423: Was 8 men or fewer. The centurion , or company commander, had a double-sized tent for his quarters, which served also as official company area. Other than there, the men had to find other places to be. To avoid mutiny, it was important for the officers to keep them busy. A covered portico might protect the walkway along the tents. If barracks had been constructed, one company was housed in one barracks building, with

13664-513: Was a geometric exercise conducted by experienced officers called metatores , who used graduated measuring rods called decempedae ("10-footers") and gromatici who used a groma , a sighting device consisting of a vertical staff with horizontal cross pieces and vertical plumb-lines. Ideally the process started in the centre of the planned camp at the site of the headquarters tent or building ( principia ). Streets and other features were marked with coloured pennants or rods. Richardson writes that from

13786-430: 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

13908-548: Was also used by Spanish colonizers in America following strict rules by the Spanish monarchy for founding new cities in the New World . Many of the towns of England still retain forms of the word castra in their names, usually as the suffixes "-caster", "-cester" or "-chester" – Lancaster , Tadcaster , Worcester , Gloucester , Mancetter , Uttoxeter , Colchester , Chester , Manchester and Ribchester for example. Castle has

14030-648: 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

14152-517: 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

14274-435: 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

14396-478: 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

14518-407: Was quadrangular, aligned on the cardinal points of the compass. The construction crews dug a trench ( fossa ), throwing the excavated material inward, to be formed into the rampart ( agger ). On top of this a palisade of stakes ( sudes or valli ) was erected. The soldiers had to carry these stakes on the march. Over the course of time, the palisade might be replaced by a brick or stone wall, and

14640-408: Was the garment of soldiers. Every camp included "main street", which ran through the camp in a north–south direction and was very wide. The names of streets in many cities formerly occupied by the Romans suggest that the street was called cardo or cardus maximus . This name applies more to cities than it does to ancient camps. Typically "main street" was the via principalis . The central portion

14762-424: Was used as a parade ground and headquarters area. The "headquarters" building was called the praetorium because it housed the praetor or base commander ("first officer"), and his staff. In the camp of a full legion he held the rank of consul or proconsul but officers of lesser ranks might command. On one side of the praetorium was the quaestorium , the building of the quaestor (supply officer). On

14884-574: Was used for fortlets, typically occupied by a detachment of a cohort or a centuria . Castrum appears in Oscan and Umbrian , two other Italic languages , suggesting an origin at least as old as Proto-Italic language . Julius Pokorny traces a probable derivation from *k̂es-, schneiden ("cut") in *k̂es-tro-m, Schneidewerkzeug ("cutting tool"). These Italic reflexes based on *kastrom include Oscan castrous ( genitive case ) and Umbrian castruo , kastruvuf ( accusative case ). They have
