Prominent bivallate partial contour hillfort located at W end of ridge marking highest point in area and at headwaters of tributary of Sandyhaven Pill flowing into Milford Haven. Steep surrounding slopes to N and S, very steep to E and W. Commanding position with extensive views. Roughly wedge-shaped measuring c. 56m N-S by 73m, with internal area 0.35ha. Defined by concentric double bank and ditch system, with additional rampart on all but W side. Inner rampart and ditch best preserved, bank formerly to c. 4.2m high from base of ditch and 1.7m high from interior and c. 11m wide, with ditch to 5m wide, now traceable on all but W. Main entrance on W, with two other gaps through inner rampart also possibly original. That on S inturned, the other on N angular. A possible phased construction has been suggested by RCAHMW (Coflein). Pasture interior, some scrub on banks and site formerly ploughed. On 1st Ed. OS map (1874-1876). Minimal investigations, undated.
