Summary

Formerly an isolated inland promontory site situated on a bluff high above bend of the Afon Teifi. Steep slopes on NE to S side, with level ground to N and W. Measures c. 75m deep, with internal area 1.12ha. Promontory cut off on N and W by two curving and widely-spaced ramparts and ditches, the inner c. 124m long, with entrance to S end, and the outer c. 50m, with inturned entrance, also at S end. WWII excavations (no details) to parts of ramparts and interior, in advance of prison camp building, found inner enclosure had palisade running along summit of the promontories natural slopes. Four roundhouses in the lee of the inner rampart investigated. Finds from this area included nails, coal fragments and a broken amber bead, possibly indicating Romano-British use. Virtually destroyed. Pasture interior. Woodland surrounds to E and S. On 1st Ed. OS map (1888).
