Roman Site in Brampton, Carlisle
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. Leahill turret spans 13.5 feet by 14.5 feet.
The turret has the remains of foundation walls just over 3 feet high and was constructed independently of the wall standing beside it as a freestanding structure.
Leahill Turret was erected around AD 122 but was torn down under Emperor Severus in the early 3rd century, and briefly reoccupied in the 4th century. Only the foundation walls remain, to a maximum height of just over 1 metre.
