HER: Glamorgan Gwent 00972g (None)
NMR: SO 40 SE 25 (306487)

Isolated sub-circular hillslope site located on spur above the River Wye but also at the headwaters of a stream tributary of the River Usk. Surrounding slopes moderate to strong to N and steep to S, E and W. Measures 32m by 35m diameter, with internal area of 0.25ha. To S land falls away suddenly c. 20m to c. 200m OD. Sometimes recorded as univallate, it is in fact bivallate owing to parlous nature of outer circuit. Inner bank and ditch visible to c.1m-1.5m outside and 0.4m-0.6m inside. Outer bank mostly only c. 0.4m, but nearly lost on S where quarrying and animal damage. Here possible annexe. Near SW corner gap in inner bank flanked on one side by heightened and thickened bank terminal, possibly oblique. Undulations and stone piles in interior possibly result of field clearance. Possible vague single hut platform, c. 7m diameter visible on platform sunk into N side. Depressions outside enclosure probably result of quarrying rather than hut platforms. Rough pasture and scrub. On 1st Ed. OS map (1881). Minimal investigations, undated.
