Univallate inland promontory fort with annexe located on a prominent and sharp SE-facing spur at the confluence of a stream with the headwaters of the Afon Gronw, a tributary of the Afon Taf. Steep surrounding slopes, less on NW along promontory. Wooded and steep stream valleys. Interior triangular shaped, c. 75m N-S by 90m at its widest behind the bank. Good natural defence on E, S and W, scarped along top to provide additional protection. Strong curving rampart, c. 90m long, with ditch cuts off the promontory on the easily approachable NW side. Bank rises to c 5m above the ditch and 2.3m above the interior, the ditch being c. 10m wide and 2m deep. A counterscarp bank is weaker. Entrance between E terminal of the bank and the steep slope, and here the counterscarp is clubbed. Annexe to N with rampart c. 30m from main rampart. This outer rampart weaker than the inner, c. 2m high with mostly filled-in ditch to 1m deep. At SW end annexe rampart curves to SE running up to the inner rampart. Two, probably modern, gaps in the annexe rampart. Roman coins found in 1800 on site according to RCAHM in 1917. Under improved pasture. On 1st Ed. OS map (1889). Minimal investigations, undated. I
