Summary

A multiple enclosures hillfort, on SW-facing spur of isolated plateau above the Afon Aeron to SW and the Nant y Drindod to NW. Steep surrounding slopes, less on NE. Ovoid in shape, measuring c. 160m E-W by 110m overall, with total area 1.8ha and internal measurements as c. 110m ENE-WSW by 60m, with area c. 0.65ha. Defined by two widely separated banks without ditches. Inner bank to 2m high has quarry ditch inside. Outer circuit, c. 20m distant on W and NW, reduced to c. 10m elsewhere. Along SE, where the two circuits produce a distinctive terrace, it is visible in erosion features as a slab-faced wall. Counterscarp on NW. Inner NW-facing entrance. Outer entrance is set at a re-entrant on the NNW and offset from the inner. The E bank terminals of both entrances appear to have been expanded/enhanced. Holloway, probably contemporary, approaching hillfort entrance. Surface evidence of huts and quarry hollows in interior. Field system outside fort to NW. Rough grazing interior with some scrub on banks. On 1st Ed. OS map (1885-1900). Minimal investigations, undated.

Interior Features

Footings of roundhouse. Quarry ditch inside inner bank. Aerial reconnaissance by RCAHMW 1999 shows tripartite internal hut. Possibly three overlapping rings representing different hut phases, or central hut with two accreted 'D'-shaped enclosures. Possible building platform.

Surface

Inside, footings of a roundhouse, 6m diameter, surviving as low turf covered wall. Quarry ditch inside inner bank, 7m-10m across and most clearly defined on the SE, where its inner edge appears kerbed. Possible building platform c. 10m in diameter, across quarry ditch on E of NW-facing entrance.
