Bivallate inland promontory fort occupying a prominent site on a SE-facing spur between confluence of two steep-sided small streams running into Milford Haven. Moderate to strong surrounding slopes, steeper on E, S and SW. Semi-circular interior measuring c. 88m NE-SW by 58m, with internal area 0. 44ha. Two substantial semi-circular ramparts with outer ditch and counterscarp cut off the promontory on N and W, elsewhere natural scarps defend the site. Inner bank best, rising to 5m above the ditch. Outer less, rising to 1.8m above a medial ditch, with traces of outer ditch. Outer bank fades at S end where slope steeper. Entrance on NW where defences end before natural fall, but wide and damaged gap here. Pasture interior with wooded, bracken and scrub banks. Wooded. On 1st Ed. OS map (1875). Minimal investigations, undated.
