Summary

Badly eroded, but strongly defended, multivallate coastal promontory fort located on S-facing promontory dominating coast to E and W near St David's. Very steep to precipitous 30m high sea cliffs to E, S and W. Severely cut into by sea on W to form massive, precipitous and eroding inlet, part isolating banks from interior and leaving c. 45m of gap. which widens out into c. 100m E-W by 50m cliff-girt interior. As a result banks appear off-set from interior which would not have been the case in prehistory. Eventually sea will cut through this gap further isolating banks from interior. Three to four rubble banks and ditches cut off the promontory on N for c. 100m-140m. Inner bank to S stands c. 3m above ditch, and to N another, slighter, bank to 1.5m above another ditch. Two further banks and ditches to N to 2.4m and 4m above the ditch respectively. Two outer banks stop 30m short of cliff. Possible entrance on E, where gap in inner banks which continue in lesser form to cliff edge. Possible traces of three hut sites in interior, but no details. Coastal grassland, brambles and scrub on banks with bare rock. On 1st Ed. OS map (1889). Minimal investigations, undated.
