The Roman Marching camp, south east of Coelbren Fort is set on ground falling to the north, bounded on all sides but the east by the marshy valleys of the Camnant and Afon Pyrddin. The camp measures 438m north-south and is 332m in breadth along the north, tapering to 305m on the south. It appears to have faced north along its long axis. The ramparts are damaged by modern field walls and there are no traces of entrances.
