Hadrian's Wall (Latin : Vallum Aelium), also known as the Roman Wall, Picts' Wall, or Vallum Hadriani in Latin, is a former defensive fortification of the Roman province of Britannia, begun in AD 122 in the reign of the emperor Hadrian. Running "from Wallsend on the River Tyne in the east to Bowness-on-Solway in the west", the Wall covered the whole width of the island, as Jarrett A. Lobell says. In addition to the wall's defensive military role, its gates may have been customs posts.
A significant portion of the wall still stands and can be followed on foot along the adjoining Hadrian's Wall Path. The largest Roman archaeological feature in Britain, it runs a total of 73 miles (117.5 kilometres) in northern England. Regarded as a British cultural icon, Hadrian's Wall is one of Britain's major ancient tourist attractions. It was designated as a UNESCO World Heritage Site in 1987. In comparison, the Antonine Wall, thought by some to be based on Hadrian's wall (the Gillam hypothesis), was not declared a World Heritage site until 2008.
Hadrian's Wall marked the boundary between Roman Britannia and unconquered Caledonia to the north.The wall lies entirely within England and has never formed the Anglo-Scottish border.
The length of the Wall was 80 Roman miles (a unit of length... equivalent to about 1620 yards [or 1480 metres] in the modern measurement), or 73 modern miles.This covered the entire width of the island, from Wallsend on the River Tyne in the east to Bowness-on-Solway in the west.
Not long after construction began on the Wall, its width was reduced to be about eight feet, or even less depending on the terrain.As some areas were constructed of turf and timber, it would take decades for certain areas to be modified and replaced by stone.
Bede, a medieval historian, wrote the Wall to be standing at 12 feet high, with evidence suggesting it could have been a few feet higher at its formation.
R.S.O. Tomlin argues that along the miles-long wall there would have been a tower every third of a mile, adding more to the dimensions of the structure. This however is not an argument but a fact, as there are plentiful remains of the turrets.
Hadrian's Wall extended west from Segedunum at Wallsend on the River Tyne, via Carlisle and Kirkandrews-on-Eden, to the shore of the Solway Firth, ending a short but unknown distance west of the village of Bowness-on-Solway.The A69 and B6318 roads follow the course of the wall from Newcastle upon Tyne to Carlisle, then along the northern coast of Cumbria (south shore of the Solway Firth).
Although the curtain wall ends near Bowness-on-Solway, this does not mark the end of the line of defensive structures. The system of milecastles and turrets is known to have continued along the Cumbria coast as far as Risehow, south of Maryport.For classification purposes, the milecastles west of Bowness-on-Solway are referred to as Milefortlets.
Hadrian's Wall was probably planned before Hadrian's visit to Britain in 122. According to restored sandstone fragments found in Jarrow which date from 118 or 119, it was Hadrian's wish to keep "intact the empire", which had been imposed on him via "divine instruction".
Lobell comments on the obvious nature of the Wall, saying "if there are troublesome tribes to the north, and you want to keep them out, you build a strong defensive wall".The Historia Augusta also states that Hadrian was the first to build a wall 80 miles from sea to sea to separate the barbarians from the Romans. However, this reasoning does not cover the various reasonings Hadrian could have had in mind when commissioning the Wall's construction.
On Hadrian's accession to the throne in 117, there was unrest and rebellion in Roman Britain and from the peoples of various conquered lands across the Empire, including Egypt, Judea, Libya and Mauretania.These troubles may have influenced his plan to construct the wall as well as his construction of frontier boundaries in other areas of the Empire, but to what extent is unknown. Scholars disagree over how much of a threat the inhabitants of northern Britain really presented and whether there was any economic advantage in defending and garrisoning a fixed line of defences like the Wall, rather than conquering and annexing what has become Northumberland and the Scottish Lowlands and defending the territory with a loose arrangement of forts.
Besides a defensive structure made to keep people out, the Wall also served to keep people within the Roman province.Since the Romans had control over who was allowed in and out of the empire, the Wall was invaluable in controlling the markets and economy. Describing the Wall as a major component of the empire's frontier military strategy, Lobell argues for the psychological impact of the Wall:
For nearly three centuries, until the end of Roman rule in Britain in 410 [CE], Hadrian's Wall was the clearest statement of the might, resourcefulness, and determination of an individual emperor and of his empire.
The Wall also provided years of work for thousands of soldiers who were responsible for building and maintaining the structure which gave the further benefit of preventing any boredom for the soldiers.
Nick Hodgson suggests that the Wall's primary purpose was as a physical barrier to slow up the crossing of raiders and people intent on getting into the empire for destructive or plundering purposes.Hodgson argues that the Wall was not a last stand type of defensive line, but, instead, an observation point that could alert Romans of an incoming attack and act as a deterrent to slow down enemy forces so that additional troops could arrive for support. This is supported by another defensive measure found in front of the Wall as well – pits or holes which likely held branches or small tree trunks entangled with sharpened branches. Originally thought of as local features for the nearby fort, it is now thought that they are a general feature of Hadrian's Wall. Hodgson argues that this new discovery has reignited the discussion of the purpose of the wall and demanded a reconsideration of the long-held interpretation that it had no defensive or tactical role.
Once its construction was finished, it is thought to have been covered in plaster and then whitewashed: its shining surface reflected the sunlight and was visible for miles around.
Hadrian ended his predecessor Trajan's policy of expanding the empire and instead focused on defending the current borders, namely at the time Britain.Like Augustus, Hadrian believed in making the natural boundaries around the empire as the borders such as the Euphrates, the Rhine, and Danube Rivers. Britain, however, did not have any natural boundaries that could serve this purpose – to divide the province controlled by the Romans from the rebellious Celtic tribes in the north. Construction started in 122.
The entire length of the Wall was built with an alternating series of forts, each housing as many as 600 men, and manned milecastles, operated by "between 12 and 20 men".
It took six years to build most of Hadrian's Wall with the work coming at the hands of three Roman legions – the II Augusta, VI Victrix, and XX Valeria Victrix, (totalling 15,000 soldiers) – and some members of the Roman fleet.The production of the Wall was not out of the area of expertise for the soldiers as they travelled with their own surveyors, engineers, masons, and carpenters.
The terms "Broad Wall" and "Narrow Wall" are used to describe different sections of Hadrian's Wall. They are aptly named as they are referring to the width of a particular section as some areas are wider than others. R.G. Collingwood found evidence for the existence of a broad section of the Wall and conversely a narrow section.He argues that plans changed during construction of the Wall and its overall width was reduced, resulting in both broad and narrow sections of the Wall.
Broad sections of the Wall are around nine and a half feet wide with the narrow sections of the Wall two feet thinner, being around seven and a half feet wide.The narrow sections were found to be built upon broad foundations. Based on this evidence, Collingwood concludes that the Wall was originally due to be built between present-day Newcastle and Bowness, with a uniform width of ten Roman feet, all in stone. However, in the end, only three-fifths of the Wall was built from stone and the remaining part of the Wall in the west was a turf wall. Plans possibly changed due to a lack of resources.
In an effort to preserve resources further, the eastern half's width was therefore reduced from the original ten Roman feet to eight, with the remaining stones from the eastern half used for around five miles of the turf wall in the west.This reduction from the original ten Roman feet to eight, created the so called "Narrow Wall".
South of the Wall there is a ten feet deep, ditch-like construction known as the Vallum, which to its south is a twenty feet high mound of dirt.The Vallum and the Wall have in many ways shared pathways that led many nineteenth century thinkers to note and ponder their relation to one another.
Some evidence shows the pathway of the Wall was shifted to avoid the Vallum, possibly pointing to the Vallum being an older construction.Collingwood therefore asserted in 1930, that the Vallum was built before the Wall in its final form. Collingwood also questioned whether the Vallum was in fact an original border built before the Wall, defining the end of Roman territory. Based on this consideration, the Wall could be viewed as a new, replacement border, built to strengthen the Roman's definition of their territory.
However, in 1936, further research suggested that the Vallum could not have been built before the Wall because it clearly avoided one of its milecastles.This new discovery was continually supported by more evidence, strengthening the idea that there was a simultaneous construction of the Vallum and the Wall.
Other evidence still pointed in other, slightly different directions. Evidence shows that the Vallum preceded sections of the Narrow Wall specifically; and, to account for this discrepancy, Couse suggests that either construction of the Vallum began with the Broad wall, or it began when the Narrow Wall succeeded the Broad Wall but proceeded more quickly than that of the Narrow Wall.
From Milecastle 49 to the western terminus of the wall at Bowness-on-Solway, the curtain wall was originally constructed from turf, possibly due to the absence of limestone for the manufacture of mortar.Subsequently, the Turf Wall was demolished and replaced with a stone wall. This took place in two phases; the first (from the River Irthing to a point west of Milecastle 54), during the reign of Hadrian, and the second following the reoccupation of Hadrian's Wall subsequent to the abandonment of the Antonine Wall (though it has also been suggested that this second phase took place during the reign of Septimius Severus). The line of the new stone wall follows the line of the turf wall, apart from the stretch between Milecastle 49 and Milecastle 51, where the line of the stone wall is slightly further to the north.
In the stretch around Milecastle 50TW, it was built on a flat base with three to four courses of turf blocks.A basal layer of cobbles was used westwards from Milecastle 72 (at Burgh-by-Sands) and possibly at Milecastle 53. Where the underlying ground was boggy, wooden piles were used.
At its base, the now-demolished turf wall was 6 metres (20 feet) wide, and built in courses of turf blocks measuring 46 cm (18 inches) long by 30 cm (12 inches) deep by 15 cm (6 inches) high, to a height estimated at around 3.66 metres (12.0 feet). The north face is thought to have had a slope of 75%, whereas the south face is thought to have started vertical above the foundation, quickly becoming much shallower.
Above the stone curtain wall's foundations, one or more footing courses were laid. Offsets were introduced above these footing courses (on both the north and south faces), which reduced the wall's width. Where the width of the curtain wall is stated, it is in reference to the width above the offset. Two standards of offset have been identified: Standard A, where the offset occurs above the first footing course, and Standard B, where the offset occurs after the third (or sometimes fourth) footing course.
Lobell says that following construction, and "when fully manned" almost 10,000 soldiers were stationed on Hadrian's Wall, made up not of the legions who built it "but by regiments of auxiliary infantry and cavalry drawn from the provinces".
Following from this David J. Breeze laid out the two basic functions for soldiers on or around Hadrian's Wall.Breeze says that soldiers who were stationed in the forts around the Wall had the primary duty of defence; at the same time, the troops in the milecastles and turrets had the responsibility of frontier control. Evidence, as Breeze says, for soldiers stationed in forts is far more pronounced than the ones in the milecastles and turrets.
Breeze discusses three theories about the soldiers on Hadrian's Wall. One, these soldiers who manned the milecastles and turrets on the Wall came from the forts near the Wall; two, regiments from auxiliaries were specifically chosen for this role; or three, "a special force" was formed to man these stations.
Breeze comes to the conclusion that through all the inscriptions gathered there were soldiers from three, or even four, auxiliary units at milecastles on the Wall.These units were "cohors I Batavorum, cohors I Vardullorum, an un-numbered Pannonian cohort, and a duplicarius from Upper Germany". Breeze adds that there appears to be some legionaries as well at these milecastles.
Breeze also continues saying that evidence is "still open on whether" soldiers who manned the Wall milecastles were from nearby forts or were specifically chosen for this task, and further adds that "the balance [of evidence] perhaps lies towards the latter".And finally, a surprise for Breeze is that "soldiers from the three British legions" outnumbered the auxiliaries which goes against the assertion "that legionaries would not be used on such detached duties".
Further information on the garrisoning of the wall has been provided by the discovery of the Vindolanda tablets, such as the record of an inspection on 18 May of a year 92 and 97, where only 456 of the full quota of 756 Belgae troops were present, the rest being sick or otherwise absent.
In the years after Hadrian's death in 138, the new emperor, Antoninus Pius, left the wall occupied in a support role, essentially abandoning it. He began building a new wall called the Antonine Wall about 160 kilometres (100 mi) north, across the isthmus running west-south-west to east-north-east. This turf wall ran 40 Roman miles, or about 60.8 km (37.8 mi), and had significantly more forts than Hadrian's Wall. This area later became known as the Scottish Lowlands, sometimes referred to as the Central Belt or Central Lowlands.
Antoninus was unable to conquer the northern tribes, so when Marcus Aurelius became emperor, he abandoned the Antonine Wall and reoccupied Hadrian's Wall as the main defensive barrier in 164. In 208–211, the Emperor Septimius Severus again tried to conquer Caledonia and temporarily reoccupied the Antonine Wall. The campaign ended inconclusively and the Romans eventually withdrew to Hadrian's Wall. The early historian Bede (AD 672/3-735), following Gildas, wrote (circa AD 730):
[the departing Romans] thinking that it might be some help to the allies [Britons], whom they were forced to abandon, constructed a strong stone wall from sea to sea, in a straight line between the towns that had been there built for fear of the enemy, where Severus also had formerly built a rampart.— Bede, Historia Ecclesiastica gentis Anglorum , Book I Chapter 12
Bede obviously identified Gildas's stone wall as Hadrian's Wall (actually built in the 120s) and he would appear to have believed that the ditch-and-mound barrier known as the Vallum (just to the south of and contemporary with, Hadrian's Wall) was the rampart constructed by Severus. Many centuries would pass before just who built what became apparent.
In the same passage, Bede describes Hadrian's Wall as follows: "It is eight feet in breadth, and twelve in height; and, as can be clearly seen to this day, ran straight from east to west." Bede by his own accountlived his whole life at Jarrow, just across the River Tyne from the eastern end of the Wall at Wallsend, so as he indicates, he would have been very familiar with the Wall. What he does not say is whether there was a walkway along the top of the wall. It might be thought likely that there was, but if so it no longer exists.
In the late 4th century, barbarian invasions, economic decline and military coups loosened the Empire's hold on Britain. By 410, the estimated end of Roman rule in Britain, the Roman administration and its legions were gone and Britain was left to look to its own defences and government. Archaeologists have revealed that some parts of the wall remained occupied well into the 5th century. It has been suggested that some forts continued to be garrisoned by local Britons under the control of a Coel Hen figure and former dux. Hadrian's Wall fell into ruin and over the centuries the stone was reused in other local buildings. Enough survived in the 7th century for spolia from Hadrian's Wall (illustrated at right) to find its way into the construction of St Paul's Church in Monkwearmouth-Jarrow Abbey, where Bede was a monk. It was presumably incorporated before the setting of the church's dedication stone, still to be seen in the church, precisely dated to 23 April 685.
The wall fascinated John Speed, who published a set of maps of England and Wales by county at the start of the 17th century. He described it as "the Picts Wall" (or "Pictes"; he uses both spellings). A map of Newecastle (sic), drawn in 1610 by William Matthew, described it as "Severus' Wall", mistakenly giving it the name ascribed by Bede to the Vallum. The maps for Cumberland and Northumberland not only show the wall as a major feature, but are ornamented with drawings of Roman finds, together with, in the case of the Cumberland map, a cartouche in which he sets out a description of the wall itself.
Much of the wall has now disappeared. Long sections of it were used for roadbuilding in the 18th century,especially by General Wade to build a military road (most of which lies beneath the present day B6318 "Military Road") to move troops to crush the Jacobite insurrection. The preservation of much of what remains can be credited to John Clayton. He trained as a lawyer and became town clerk of Newcastle in the 1830s. He became enthusiastic about preserving the wall after a visit to Chesters. To prevent farmers taking stones from the wall, he began buying some of the land on which the wall stood. In 1834, he started purchasing property around Steel Rigg near Crag Lough. Eventually, he controlled land from Brunton to Cawfields. This stretch included the sites of Chesters, Carrawburgh, Housesteads, and Vindolanda. Clayton carried out excavation at the fort at Cilurnum and at Housesteads, and he excavated some milecastles.
Clayton managed the farms he had acquired and succeeded in improving both the land and the livestock. He used the profits from his farms for restoration work. Workmen were employed to restore sections of the wall, generally up to a height of seven courses. The best example of the Clayton Wall is at Housesteads. After Clayton's death, the estate passed to relatives and was soon lost at gambling. Eventually, the National Trust began acquiring the land on which the wall stands. At Wallington Hall, near Morpeth, there is a painting by William Bell Scott, which shows a centurion supervising the building of the wall. The centurion has been given the face of John Clayton.
Hadrian's Wall was declared a World Heritage Site in 1987, and in 2005 it became part of the transnational "Frontiers of the Roman Empire" World Heritage Site, which also includes sites in Germany.
Although Hadrian's Wall was declared a World Heritage Site in 1987, it remains unguarded, enabling visitors to climb and stand on the wall, although this is not encouraged, as it could damage the historic structure. On 13 March 2010, a public event Illuminating Hadrian's Wall took place, which saw the route of the wall lit with 500 beacons. On 31 August and 2 September 2012, there was a second illumination of the wall as a digital art installation called "Connecting Light", which was part of the London 2012 Festival. In 2018, the organisations which manage the Great Wall of China and Hadrian's Wall signed an agreement to collaborate for the growth of tourism and for historical and cultural understanding of the monuments.
In 2003, a National Trail footpath was opened that follows the line of the wall from Wallsend to Bowness-on-Solway.Because of the fragile landscape, walkers are asked to follow the path only in summer.
Hadrian's Wall was known in the Roman period as the vallum (wall) and the discovery of the Staffordshire Moorlands Pan in Staffordshire in 2003 has thrown further light on its name. This copper alloy pan (trulla), dating to the 2nd century, is inscribed with a series of names of Roman forts along the western sector of the wall: MAIS [Bowness-on-Solway] COGGABATA [Drumburgh] VXELODVNVM [Stanwix] CAMBOGLANNA [Castlesteads]. This is followed by RIGORE VALI AELI DRACONIS. Hadrian's family name was Aelius, and the most likely reading of the inscription is Valli Aelii (genitive), Hadrian's Wall, suggesting that the wall was called by the same name by contemporaries. However, another possibility is that it refers to the personal name Aelius Draco.

The Latin and Romano-Celtic names of all of the Hadrian's Wall forts are known, from the Notitia Dignitatum and other evidence such as inscriptions:
Turrets on the wall include:
Outpost forts beyond the wall include:
Supply forts behind the wall include:
A milecastle was a small fort (fortlet), a rectangular fortification built during the period of the Roman Empire. They were placed at intervals of approximately one Roman mile along several major frontiers, for example Hadrian's Wall in Great Britain, hence the name.
Hadrian's Wall Path is a long-distance footpath in the north of England, which became the 15th National Trail in 2003. It runs for 84 miles (135 km), from Wallsend on the east coast of England to Bowness-on-Solway on the west coast. For most of its length it is close to the remains of Hadrian's Wall, the defensive wall built by the Romans on the northern border of their empire. This is now recognised as part of the "Frontiers of the Roman Empire" World Heritage Site.
The Vallum is a huge earthwork associated with Hadrian's Wall in England. Unique on any Roman frontier, it runs practically from coast to coast to the south of the wall.
Milecastle 18 was a milecastle of the Roman Hadrian's Wall. It is located to the west of the settlement of East Wallhouses in Northumberland and is visible as a platform in the ground. The milecastle is of a unique construction, having a gateway associated with builders of the Legio II Augusta and a layout typical of the Legio VI Victrix or Legio XX Valeria Victrix. Historians have suggested that it may have been begun by men of one legion and finished by those of another. One of Milecastle 18's associated turrets shows evidence of being used as a workshop, possibly for the repair of shoes.
Maia, or Mais, in Cumbria, England was a Roman fort on Hadrian's Wall, and was the last fort at the western end of the Wall, overlooking the Solway Firth.
Milecastle 7 was a milecastle of the Roman Hadrian's Wall. The milecastle itself has not been discovered by archaeologists and its presumed location lies beneath a modern housing development. Roman finds have been made in the area and the associated structure of Turret 7B is a significant surviving structure of the wall.
Leahill Turret is a typical example of one of the lookout towers located between the milecastles on Hadrian's Wall in Cumbria; located on the Lanercost Road near Banks, Parish of Waterhead. It is designated turret 51b and lies east of the Signal Tower at Pike Hill.
The Military Way is the modern name given to a Roman road constructed immediately to the south of Hadrian's Wall.
Milecastle 10 was a milecastle of the Roman Hadrian's Wall. It is located near to the modern village of Throckley in Tyne and Wear, northern England. Much of the milecastle lies beneath a road but partial remains of the north wall can be seen in the garden of Dene House. It has been excavated several times and its walls located, though the remains have been "considerably damaged by ploughing". Only one of the two associated turrets has been located and excavated.
Milecastle 19 was a milecastle of the Roman Hadrian's Wall. Sited just to the east of the hamlet of Matfen Piers, the milecastle is today covered by the B6318 Military Road. The milecastle is notable for the discovery of an altar by Eric Birley in the 1930s. An inscription on the altar is one of the few dedications to a mother goddess found in Roman Britain, and was made by members of the First Cohort of Varduli from northern Spain. The presence of the Vardulians at this milecastle has led to debate amongst archaeologists over the origins of troops used to garrison the wall. A smaller altar was found at one of the two associated turrets.
Milecastle 22 (Portgate) was a milecastle of the Roman Hadrian's Wall. Its remains exist as a low, turf covered platform just east of the Portgate roundabout. The platform is 0.5 metres (1.6 ft) on the east side, reducing to only a parch mark on the west side.
Milecastle 23 (Stanley) was a milecastle of the Roman Hadrian's Wall. Its remains exist as a low, grass covered platform with traces of an external ditch. It is located to the south of the B6318 Military Road around 1.5 kilometres (0.93 mi) west of its junction with the A68.
Milecastle 80 was one of a series of Milecastles or small fortlets built at intervals of approximately one Roman mile along Hadrian's Wall.
Milecastle 79 was one of a series of Milecastles or small fortlets built at intervals of approximately one Roman mile along Hadrian's Wall.
Milecastle 27 was a milecastle of the Roman Hadrian's Wall. It was located on the line of Hadrian's Wall, approximately midway between the A6079 and the River North Tyne. Its remains survive as a slight squarish platform with a maximum height of 0.4 metres (1.3 ft), but it is poorly defined to the north and east.
Milecastle 29 was a milecastle of the Roman Hadrian's Wall. Its remains exist as a mutilated earth platform accentuated by deep robber-trenches around all sides, and are located beside the B6318 Military Road. Like Milecastles 9, 23, 25, and 51, a ditch has been identified around the Milecastle, and is still visible to a small extent. It has been postulated that this was as a result of the need for drainage on the site.
Limestone Corner is an area of Hadrian's Wall at its most northerly point, in present-day northern England. It represents the most northerly point of the Roman Empire, outside the two periods during which the Antonine Wall was occupied by the Roman military. Other notable features at Limestone Corner are the wall ditch at this point, which was never completely excavated, a Roman camp and the site of Milecastle 30. Also present is a trig point. The B6318 Military Road also runs through Limestone Corner, as does the Military Way, serving Milecastle 30. The Military Way is visible on the ground at this point, the most eastern point where this is the case.
A turret was a small watch tower, incorporated into the curtain wall of Hadrian's Wall. The turrets were normally spaced at intervals of one third of a Roman mile between Milecastles, giving two Turrets between each Milecastle.
Milecastle 65 (Tarraby) was a milecastle on Hadrian's Wall.
Milecastle 50TW was a milecastle on the Turf Wall section of Hadrian's Wall. The milecastle is located close to the Birdoswald Roman Fort and is unique in that it was not replaced by a stone milecastle when the turf wall was upgraded to stone, the replacement wall instead running some 200m to the north. The milecastle was partially demolished by the Romans after it was abandoned. The milecastle was excavated in 1934 and several Roman rubbish pits discovered. The remains of the two turrets associated with this milecastle have also been located. As the turf wall lies some distance from the stone wall, the sites are not accessible from the Hadrian's Wall Path.
