Summary

Univallate inland promontory fort located on S-facing spur falling c. 30m to steep wooded valley of Rhyd-y-Brown Brook on E, a stream tributary of the Afon Syfynwy, and wooded stream valley to SE and S and confluence of both to SW. Steep surrounding slopes to E, S and W, gentle to moderate along spur to N. Natural slopes on E, S and W, with single rampart c. 65m long and to 2m high, and filled-in ditch cutting off the promontory on N. At W end rampart stops 5m short of the steep drop to stream and here possible entrance. Modern access gap in centre reveals earth and clay construction of bank. On S side just possible that slope scarped. Interior trapezoidal in shape slopes to S measuring c. 82m N-S by 70m, with internal area 0.23ha. Undulations in interior of uncertain nature. Improved pasture interior with grass and deciduous trees on bank. In fair condition, but modern gap eroding. Minimal investigations, undated.
