Bivallate promontory fort on steep-sided limestone spur overlooking Caswell Bay and bay from Pwlldu to Whitehell Point. Surrounding E side very steep, other sides less so. Level area of the promontory, c.55m by 30m to 0.2ha internal area, cut off N-S on the only easy approach from the W by two widely-spaced ramparts c. 45m apart. Outer, possibly following modern field boundary, is hardly visible, but its V-shaped ditch shows for some 20m to a depth of up to 2m. The inner shows a bank, c. 4.5m wide and up to 0.6m high, also with V-shaped ditch visible for some 50m across the promontory. No entrance discernible. Interior very craggy and overgrown, making interpretation difficult, and no traces of habitation. On OS 1:25,000 map (1937-1961). Minimal investigations, undated.
