Bar Hill Fort is oddly enough not situated on the Antonine wall itself. Instead, it’s set about 30 metres south of the wall, with the Military Way road running between.

Within the fort are traces of an earlier enclosure, probably a temporary camp set up during the construction of the wall. A second probable temporary camp has also been found just south-west of the fort.

When it was completed, the Antonine Wall was the most complex frontier ever built by the Roman Army. It was the Romans’ last linear frontier, and was only occupied for about 20 years before it was abandoned in the AD 160s.
