Castle Folds Romano-British defended stone hut circle settlement and medieval shieling

Castle Folds is a ruined Romano-British settlement on Great Asby Scar, a stretch of limestone pavement in Cumbria’s North West. The site sits on a small knoll surrounded by thick stone walls built from upright slabs. These walls once rose about thirteen feet high, with a central open space and a dozen stone huts built into them. The walls were later reused in medieval times as a shieling, a simple summer shelter for herders. The settlement’s defences were unusually strong for its kind, using massive orthostats and a high parapet. Archaeologist R. G. Collingwood linked its design to the Brigantes’ forts described by the Roman-era writer Juvenal. Evidence of deliberate destruction shows the walls were torn down by force, suggesting the site saw serious conflict. Today the ruins stand on the bare limestone pavement, with the medieval shieling’s rectangular outline still visible beside the south wall. The remains of the stone huts and the shattered enclosure walls give a clear sense of the site’s past strength and later use. Visitors walk over the exposed limestone, tracing the outlines of walls and rooms that once sheltered people nearly two thousand years ago.
