Isolated bivallate coastal promontory fort sited on NW-facing coastal headland plateau near a small bay to SW and near to where the Afon Fynnon Ddewi meets the sea to NE. Sea cliffs to N and W, steep slopes to E and S. Most northerly of coastal promontory forts in Ceredigion. Rampart circuit now possibly only a quarter of what could have been a circle in prehistory and interior of the fort now very small as a result of substantial sea erosion. Two curving banks, c. 2m in height, with ditches, c. 90m long, cross the easily approachable E side, enclosing c. 0.3ha. Second slighter bank with stone revetment sited c. 107m to E, extending from a natural scarp to the sea cliffs and perhaps forming a concentric annexe. Total internal area c. 1.12ha. Survey by K. Ray (undated) suggested that inner enclosure originally had a single bank and ditch, and that the second was added at the same time as the slighter outer bank to E. Many circular features visible within outer enclosure, two plus c. 7.5-10m across, and possibly stone-founded circular structures, or roundhouses. Coastal grassland. On 1st Ed. OS map (1889). Minimal investigations, undated.
