Leahill Turret

Hob Uid: 12622
Location :
Cumbria
Carlisle
Waterhead
Grid Ref : NY5838065110
Summary : The site of Leahill Turret, also known as Turret 51B, was built shortly after AD 122 as part of Hadrian's Wall, dismantled under Severus and casually re-occupied late in the fourth century AD. It was located in 1927 and found to be an independent structure abutting the Wall. The Turret was excavated in 1958, which found that the internal measurements were 13 feet 8 inches north-south by 14 feet 6 inches east-west. There were slight remains of an earlier turf turret to the east and west of the stone structure, which had been overlaid by occupation material. The stone turret had been much robbed, surviving to a maximum height of 9 courses. However, a platform was found in the centre of the north wall. The turret has since been consolidated and survives to a maximum height of 1.1 metres.

Turret 51B, examined in 1958, was dismantled under Severus and casually re-occupied late in the fourth century. Its south wall is visible in the north verge of the modern road, and its close proximity to the Wall-ditch is typical of the Turf-Wall structures. Six courses of external wall showing on roadside, also entrance. (2)

The remains have been consolidated by the MOW. (3)

Excavated in 1958 in advance of consolidation work by MPBW and was found to have gone out of occupation in the Antonine period, but had not been dismantled nor the Great Wall taken over the recess. (5)

Four walls now visible standing to a height of 0.8m. Surveyed at 1:2500. (6)

The turret was located in 1927 and found to be an independent structure abutting the Wall (7a). The 1958 excavations (see auth 5) found that the internal measurements of the turret were 13 feet 8 inches N-S by 14 feet 6 inches E-W. There were slight remains of the turf turret to the E and W of the stone structure which had been overlaid by occupation material. The stone turret had been much robbed surviving to a maximum height of 9 courses; a platform was found in the centre of the N wall (7b). The turret is now consolidated and under guardianship with a maximum height of 1.1m. The correct NGR is NY 5838 6511. (7)

The remains of this turret are visible on aerial photographs taken in 1972.(8)

Located on the English Heritage map of Hadrian's Wall 2010. (9)
