|A Roman marching camp is suspected just to the south-west of the Bar Hill fort. A single ditch observed from the air and investigated by the spade, was found to be V-shaped in section, about 6½ ft wide by 2¾ ft. deep (c.2 x 0.8 m). Although the complete outline has not been recorded, constrictions of topography suggest that the camp covered an area of no more than about 1½ acres (c.0.6 ha). The northern defences were proved by excavation in 1983 whereupon the remains of wooden tent-pegs were recovered from the ditch. It is possible that this site represents part of a labour-camp associated not with the Antonine barrier, but specifically with the construction of the Bar Hill fort itself.|
Although the evidence for the Bar Hill camp is inconclusive, there is another marching camp close to the Wall nearby at Twechar (NS6975) and a Roman fortlet a little way south of the Wall at Mollins (NS7171).
