Rampart, ditch, causeways and defensive pits still make Rough Castle one of the easiest Antonine Wall forts to understand on the ground. The Roman fort stands against the rear face of the Antonine Wall, the frontier barrier across central Scotland, and preserves the outline of both military planning and frontier defence.
What follows is drawn from published sources, with each claim labelled by how firmly it is established.
History
The Antonine Wall dates from about 143 AD, and Rough Castle was built against the southern rear face of the wall. The wall's eastern and western ends were long debated, with Carriden near Bo'ness likely in the east and Old Kilpatrick on the Clyde in the west.
Rough Castle is one of the best-preserved forts built along the wall. It was defended by turf ramparts six metres thick and by surrounding ditches, with gateways through the wall to the north and through the other sides of the fort.
Causeways were constructed across the main Antonine ditch and secondary defensive ditches to allow movement to and from the fort. The military road on the south side of the wall, used for transport between forts, remains well defined.
The fort was the second smallest on the wall, covering about 4,000 square metres. Excavations in 1902-03, 1932 and 1957-61 found the foundations of the commander's house, barracks, headquarters, bath house and granary.
Inscriptions on recovered artefacts show that the fort housed 480 men of the Cohors VI Nerviorum, foot soldiers drawn from the Nervii, a north-eastern Gallic tribe. The source also names Flavius Betto as a commanding officer.
A sound and light show was organised at Rough Castle in November 2018 to promote tourism, showing the continuing public role of the fort within the Antonine Wall landscape.
