Summary

Contour hillfort, the largest of a cluster of mostly small forts around The Mule watercourse, a tributary of the River Severn, and up to the Kerry Ridgeway. Surrounding slopes to N precipitous, S moderate to strong, E steep and W moderate. D-shaped in plan measuring c. 120m E-W by 90m with internal area at least c. 0.6ha. Two scarped banks on S and W, c. 15m and 10m apart respectively, to 1.8m high on S to 0.8m high on W, where reduced by agriculture. Quarry to SE corner. N from quarry single bank c. 10m wide 0.5m high ending abruptly c. 30m from the ravine. All works now hardly visible. Possibly third rampart on W (Hughes 1928), but not visible by CPAT (2007). No ditches. Two possible entrances, on NE, within the gap referred to above, another possibly at junction of single and double banks on SE. Site much eroded. Pasture interior with wooded surrounding slopes to N and E. On 1st Ed. OS map (1885). Minimal investigations, undated.
