Milecastle 39 at Castle Nick lies to the west of the Roman fort at Housesteads. This photograph was taken in the early 1980s, prior to the excavations in 1985-87. The internal buildings have since been uncovered, and Hadrian’s Wall to the east has now been conserved and restored. Notice the makeshift ramp in the north-east corner of the milecastle providing access to the wall itself. The spoil heaps on the east and west sides of the milecastle have now been removed. The path has been moved away from the line of the wall.
