Reasons for Designation

Hadrian's Wall marks one of the frontiers of the Roman Empire. The international importance of the surviving remains has been recognised through designation as a World Heritage Site. The military importance of the Tyne-Solway route across the Pennines was recognised by the Romans during their early campaigns through northern England and into Scotland in the second half of the first century AD. At this time a military road, the Stanegate, was constructed along with a series of forts. Subsequently the Romans largely withdrew from Scotland and there is evidence that the Tyne-Solway route was being recognised as a frontier by the start of the second century AD. This position was consolidated in the early second century by the construction of a substantial frontier work, Hadrian's Wall, under the orders of the Emperor Hadrian. Hadrian's successor, Antoninus Pius, subsequently attempted to establish the boundary further north, between the Clyde and the Firth of Forth, but by c.AD 160 growing unrest amongst the native populations of northern Britain and pressures elsewhere in the Empire caused a retraction back to the Hadrianic line. Hadrian's Wall was then the frontier of the Roman Empire in Britain until c.AD 400 when the Roman armies withdrew from Britain. Stretching over 70 miles from coast to coast, Hadrian's Wall was a continuous barrier built of stone in the east and, initially, of turf in the west. The stone wall was originally designed to be ten Roman feet wide and sections of this width are termed broad wall. A change of plan shortly after construction began led to a reduction in the width of the Wall to eight Roman feet, such sections being termed narrow wall. Today, stretches of both wall types survive, including some sections of narrow wall built on broad wall foundations. For most of its length a substantial ditch on the northern side provided additional defence. Where the Wall crossed rivers, bridges were constructed to carry it across. Construction of the Wall was organised and executed by legionary soldiers. From the beginning the barrier was planned to comprise more than just a curtain wall. At regularly spaced intervals of about a mile along its length lay small walled fortlets known as milecastles. These were attached to the southern side of the Wall and most had a gateway through the Wall to the north. Hence they controlled crossing points through the Wall as well as affording space for a small stable garrison. Between the milecastles were two equally spaced towers known as turrets. Together the milecastles and turrets provided bases from which the curtain wall could be watched and patrolled. Both the turrets and milecastles are thought to have been higher than the Wall itself to provide suitable observation points. It is often assumed that a platform existed on the Wall so that troops could actually patrol along the wall top; it is however far from certain that this was the case. At the western end of the Wall a system of towers, small fortlets and palisade fences extended the frontier system another 30 miles or so down the Cumbrian coast and helped control shipping moving across the estuary of the Solway Firth. As originally planned, and apart from whatever space there was in the milecastles, provision for the accommodation of garrison troops manning the Wall was left with the line of forts which already lay along the Stanegate. At some point a fundamental change of plan took place and forts were constructed along the line of the Wall itself. There are now known to have been 16 forts either attached to the Wall or in close association with it. Some overlay earlier features such as turrets or milecastles. At this stage another linear element, the vallum, was also added to the defensive system to the south of the Wall. This was a broad flat-bottomed ditch flanked by a pair of linear banks. It shadows the course of the Wall for almost all its length, sometimes lying very close to it but sometimes up to a kilometre away from it. The vallum's main function was to act as a barrier to restrict access to the Wall from the south. It also had a function in linking the forts along the Wall with a method of lateral communication. When the forts were placed along the wall line no provision was made for a road to link them. This situation was clearly found impracticable and a metalled track was therefore provided in places along the vallum between the north mound and the ditch. Later, after the withdrawal back to the Hadrianic line from the Antonine Wall, various refurbishments were made throughout the frontier line. At this stage a new linear feature was added: the `Military Way'. This was a road linking all elements of the Wall defence, running from fort to fort within the area bounded by the Wall and the vallum. Throughout its long history the Wall was not always well maintained. It was often neglected and sometimes overrun, but it remained in use until the late fourth century when a weak and divided Roman Empire finally withdrew its armies from the Wall and Britain. It now survives in various states of preservation. In places, especially in the central section, the Stone Wall still remains several courses high and the attached forts, turrets and milecastles are also clearly indentifiable. Earthwork features such as the ditch, vallum and Military Way also survive well in places. Elsewhere the Stone Wall has been virtually robbed out and only its foundations survive beneath the present ground surface. Similarly, stretches of the earthwork remains, including sections of the Turf Wall, have been levelled or infilled and now only survive as buried features. Although some sections of the frontier system no longer survive visibly, sufficient evidence does exist for its position to be fairly accurately identified throughout most of its length.

Hadrian's Wall and vallum and their associated features between the field boundary west of Coventina's Well and the field boundary at Brown Dikes survive well as a series of buried and upstanding remains. Significant information on the development of the frontier system over time, will be preserved.

Details

The monument includes the section of Hadrian's Wall, vallum and their associated features between the field boundary west of Coventina's Well in the east and the field boundary at Brown Dikes in the west. This section occupies a gentle east facing slope with wide views to the north and south. Hadrian's Wall survives as a buried feature throughout this section. East of Carraw Farm it is overlain by the modern field wall which defines the south side of the B6318 road. Here its line is visible as a disturbed grassy bank, 0.4m high, at the base of the modern wall. West of Carraw Farm its line is visible as a well defined robber trench, about 2m wide, beyond which it reappears as a slight scarp below the field wall which defines the south side of the road. West of here the Wall is overlain by the modern B6318 road. At Carraw Farm the survival of the remains of the Wall and wall ditch have not been confirmed. To the east and west of Carraw Farm the wall ditch is partly encroached on by the B6318 road. However, it is visible to an average depth of 1.5m. The wall ditch is best preserved at the west end of this section where it reaches a depth of 3m. The upcast from the ditch, known as the glacis, survives intermittently as a mound to the north of the ditch. It is also best preserved at the west end of this section where it averages 1.4m in height. Milecastle 32 survives as a turf covered platform with robber trenches, 0.3m deep, defining the line of its east and west walls. The south wall is defined by a terrace, while the north wall is overlain by the field wall on the south side of the B6318 road. Limited excavation during 1971 recovered pottery which suggested occupation of the milecastle continued into the fourth century AD. Turret 31b is visible as a slight mound about 80m to the east of Carraw Farm. Its doorway was in the east side. Its remains are buried below the turf cover slightly to the south of the B6318 road. The precise location of turret 32a has not yet been confirmed. However, on the basis of the usual spacing, it is expected to be situated about 500m west of milecastle 32 under the surface of the B6318 road. The course of the Roman road known as the Military Way, which ran along the corridor linking turrets, milecastles and forts is not yet known with certainty in this section. However, there is a slight rise alongside the field wall on the south side of the wooded area to the south of Carraw Farm which could be the remains of the `agger', or raised spine, of the road. The antiquarian Horsley, writing in the 1730s, stated that the Military Way was carried on the north mound of the vallum in this general area. The vallum is visible intermittently as an upstanding earthwork throughout this section. It is least well preserved at the east end where only the ditch is visible, having an average depth of 2m. West of milecastle 32 the earthworks are better preserved. The north mound is in good condition, reaching 1.5m in height, while the south mound at best reaches 0.9m. Here the ditch is waterlogged and silted, though it averages a depth of 1m. Carraw Farmhouse, its farm buidlings and garden are totally excluded from the scheduling. All road surfaces and field boundaries within the area of the monument are excluded from the scheduling, but the ground beneath is included.
