Milecastle 53 (Banks Burn) was a milecastle on Hadrian's Wall .
Milecastle 53 is west of the hamlet of Banks, Cumbria and northeast of Lanercost Priory. It lies 1520 metres west of Milecastle 52 and 1436 metres east of Milecastle 54. There is no trace of the milecastle visible.[1]
The tall section of Hadrian's Wall at Hare Hill (standing to a height of about 2.7 metres) is just 80 metres west of Milecastle 53 .[2]
Milecastle 53 was excavated in 1932. It measured 21.9 metres east to west by 23.3 metres north to south. It had Type III gateways.
The excavation found that most of the milecastle had been robbed of masonry and the original floor had been removed so that no internal buildings remained.[1] Some remnants of the earlier Turf Wall milecastle remained in the northeast corner and south section.[1]
Each milecastle on Hadrian's Wall had two associated turret structures. These turrets were positioned approximately one-third and two-thirds of a Roman mile to the west of the Milecastle, and would probably have been manned by part of the milecastle's garrison. The turrets associated with Milecastle 53 are known as Turret 53A and Turret 53B.
Turret 53A (Hare Hill) survives as a slight earthwork platform. The turret was found in 1854 or 1855, and excavated in 1932.[3] The interior was found to be full of ashes.[3]
Turret 53B (Craggle Hill) also survives as a slight earthwork platform. It was excavated in 1932.[4] The turret was the most easterly structure in Hadrian's Wall to use red sandstone.[4]
