The excavated south wall was 2.7 metres (8.9 ft) wide and bonded with clay.

Its foundations were 2.9 metres (9.5 ft) wide (as were those of the east wall and formed of flags (flag foundations are normally associated with broad wall milecastles.)

There was evidence to suggest that the southern gateway had been blocked at some time.

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.
