87-675: The Gask Ridge is the modern name given to an early series of fortifications , built by the Romans in Scotland , close to the Highland Line . Modern excavation and interpretation has been pioneered by the Roman Gask Project, with Birgitta Hoffmann and David Woolliscroft. The ridge fortifications: forts, fortlets and watchtowers were only in operation for a few years, probably fewer than ten. The name "Gask Ridge" refers to
174-402: 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
261-416: A 180–250 mm (7–10 in) nail and 25 shillings for a boxed set of five nails. David Colville & Sons (Iron and Steel refiners) was given the task of sorting and storing the nails; the process of sorting, gifting and selling all complete nails was done by 1963, three years after their discovery. The almost 2000-year-old iron nails from Inchtuthil have been used by atomic scientists to estimate
348-520: 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
435-427: 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 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
522-415: 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
609-463: A combined total weight of ten tonnes. The nails and ironwork were found in a pit which was elaborately concealed. They were almost certainly buried by the Roman troops when they dismantled the fortress before departure to deny them to the local tribes . Many of the nails were sent to museums while some of the hoard was sold to the public and other interested organisations with an offer of 5 shillings for
696-410: 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 a stockade, for which the soldiers carried stakes, and a ditch. The castra could be prepared under attack within a hollow square or behind
783-521: A defensive fortification or a jumping-off point for an invasion. The Gask Road and the towers alongside it in this hypothesis guarded the strategically important link to the harbours at the Firths of Tay and Forth and the southern part of the province. Tacitus writes in De vita Iulii Agricolae that Agricola was fighting in the area in around 80 AD; the latest coinage dates from 86 AD. This would suggest that
870-510: 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 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
957-531: 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

The timber walls of these buildings have been calculated to have had a total perimeter of 7 miles (11 km). A headquarters building containing an aedes where the legion's colours and images of the emperor would have been kept has also been identified in
1131-560: A major incursion. The smaller forts were more likely to serve as a disincentive to small-scale raiding parties. The relationship between the Glenblocker forts and the Gask Ridge has in the past been seen as a staged withdrawal. Recent research suggests that the three elements are part of the same frontier system, stretching roughly from Loch Lomond to Montrose. In this hypothesis, the Glenblocker forts controlled access to valleys in
1218-464: 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,
1305-422: 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 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
1392-473: 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 the Welsh place name prefix caer- (e.g. Caerleon and Caerwent ) and English suffixes -caster and -chester (e.g. Winchester and Lancaster ). Castrorum Filius , "son of
1479-633: A reuse of the sites contemporary with the Antonine Wall . In the Severan period the army passed through the area, and several camps across Scotland are dated to this period (for example, Kair House in Aberdeenshire and the fort at Carpow Roman Fort which is on the Firth of Tay. The permanent sites are complemented by a series of large marching camps (large camps date to the 3rd century) from
1566-628: 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
1653-524: 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
1740-557: A temporary camp was built nearby to house and protect the soldiers over the winter. Additional, smaller forts were built further north and south at the mouth of each nearby glen forming what are now referred to as the Glenblocker forts . The fort at Inchtuthil is thought to be part of the Glenblocker forts , as well as others in Strathmore, such as Cardean and Stracathro , formed a uniform system composed of several elements,
1827-409: 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

To this end a marching column ported the equipment needed to build and stock
2001-442: Is therefore notable as the site which provides the only complete plan of a legionary fortress anywhere in the Roman empire. Its defences consisted of a turf rampart faced with stone, with an outside ditch and gatehouses on each side, following the standard Roman plan. The legion it accommodated would have numbered 5,400 at full strength, though there would have been additional specialist troops accompanying them. Facilities included
2088-399: 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
2175-569: 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
2262-723: 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 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
2349-536: 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
2436-447: 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

The large empty insula to its east should have been the site for the Praetorium , the commander's house. However, no signs of building foundations for such a large structure were found though the site had been levelled and prepared. Inchtuthil
2610-612: 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
2697-503: 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

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 Roman legions in the 1st century established a chain of forts at Ardoch , Strageath , Inchtuthil , Battledykes (which is unlikely to date from the same period as the Gask sites), Stracathro and Raedykes , taking the Elsick Mounth on the way to Normandykes , before going north to Glenmaillen and Auchinhove. Unconfirmed sites of possible Roman forts have also been found at Bellie , Balnageith and Cawdor . In

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
3306-403: 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,
3393-434: 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
3480-499: 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
3567-500: 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 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

3654-400: 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

Castro , also derived from Castrum , is a common Spanish family name as well as toponym in Spain and other Hispanophone countries, Italy , and 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
3828-411: 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

It

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:
4089-658: 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

During the excavations started by Richmond in the 1950s, a large pit was found in the summer of 1960 containing 875,400 complete iron nails (Square shaft) ranging from 50–410 mm (2–16 in) plus another 28 (round shaft nails) weighing 7 short tons (6.4 t), together with other iron objects, including cartwheel rims weighing

Inchtuthil as the largest military base would have functioned as the lynch-pin and the only site large enough to launch an invasion into the Highlands and beyond. Unlike other legionary fortresses in Britain, Inchtuthil was not later built over and its layout was still largely preserved when Sir Ian Richmond excavated it between 1952 and 1965. It
4350-523: The forts were occupied for six years at most. Recent archaeology has shown that many of the forts on the Gask Ridge were rebuilt, sometimes twice, without evidence of destruction through warfare. Further digs may cast some light on this apparent contradiction. The forts of Ardoch , Strageath and Bertha on the Gask Road, as well as the forts of Cargill in Strathmore and the glenblocker fort of Dalginross have also produced Antonine material attesting to

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

Their value as a block to invasion is doubtful, as their situation would have allowed supervision but they lacked the manpower to deter anything but cattle rustling. Only the legionary fortress at Inchtuthil , conveniently situated for access into Braemar and its hinterland, is large enough to have functioned as
4611-410: 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
4698-521: 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
4785-426: 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
4872-729: 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
4959-476: 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
5046-402: 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
5133-458: 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,
5220-582: 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

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 ,

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

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

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

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

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,

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

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
6090-427: 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
6177-607: The south-west were collectively referred to as glenblocker forts in the older literature; they are also called the Highland line forts. Glenblocker describes their location at the exit of some of the glens. All of the forts were originally built during the Flavian occupation in Scotland. A broader group consists of Cardean, Stracathro and Doune are sited further away from their respective traffic corridors, although fulfilling
6264-475: 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
6351-473: 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

The diminutive form castellum 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
6525-464: 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
6612-458: 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
6699-655: The watchtowers is consistent with those on the Rhine and it is thought the Scottish ones were built first. It has traditionally been thought that these forts were meant to prevent invasions out of the Scottish Highlands into Roman-held territory. This may have been the intention, in cooperation with the other forts on the Gask Ridge and along Strathmore , as only the legionary fortress of Inchtuthil with 5,000–6,000 soldiers would have been strong enough to deal with
6786-423: 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
6873-513: 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
6960-613: 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
7047-600: Was built in AD 82 or 83 as the advance headquarters for the forces of governor Gnaeus Julius Agricola in his campaign against the Caledonian tribes. Positioned at the head of one of the main routes in and out of the Scottish Highlands , it was occupied by Legion XX Valeria Victrix and covered a total area of 21.5 hectares (53 acres). Construction of the large fortress would have taken two or three seasons and
7134-543: 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 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
7221-533: Was only briefly occupied and was evacuated around summer AD 86 and certainly no later than early in AD 87. The reason for this was probably that Legio II Adiutrix had been called to Moesia from its base in Deva Victrix ( Chester ) to deal with a Dacian invasion in 86 and XX Valeria Victrix was obliged to move back south to take its place. However recent archaeology has cast some doubt on this, indicating that
7308-407: 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
7395-590: Was started 42 years after completion of the Gask Ridge (from 122 to 130 AD), and the Antonine Wall was started 12 years after completion of Hadrian's Wall (from 142 to 144 AD). Although the Gask Ridge was not a wall, it may be Rome's earliest fortified land frontier. The fortifications approximately follow the boundary between Scotland's fertile Lowlands and mountainous Highlands , in Perth and Kinross and Angus . The later Hadrian's Wall and Antonine Wall were further south and considerably shorter. The principal forts of
7482-408: 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
7569-424: 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
