Summary

Small, multivallate, contour hillfort located on isolated and prominent site overlooking the River Wye above Hay-on-Wye to the S and the River Arrow to the N, on the interfluve between the Rivers Wye and Severn catchments, thus commanding two valleys. Roughly oval in shape, with internal area c. 0.82ha. Defences are of no great strength. Double ramparts on the W, the inner bank weaker. To the S there are no ramparts in evidence, but a hedgeline possibly preserves their location. To the N and E, only a scarp to the inner enclosure remains, with no trace of a ditch. Defences much damaged, especially on S where absent and now a hedgeline, where possible entrance, but only conjecture. Thought to be little change since the 1980's and that the site is stable in condition. Part conifer plantation and pasture. Access problems hamper investigation. Undated. On 1st Ed OS map (1888).

Entrances

Entrances not visible on the present line, nor recorded. It is possible that there was an entrance on the S line where there is now a hedge, but this is only conjecture.

Total Number of Breaks Through Ramparts:  
1:   None

Number of Possible Original Entrances:  
2:   Possible that there was an entrance on the S line where there is now a hedge, but this is only conjecture.

Guard Chambers:  ✗

Chevaux de Frise:  ✗

Entrances:
1. Simple Gap (South):   Possible that there was an entrance on the S line where there is now a hedge, but this is only conjecture.

Enclosing Works

Double ramparts on W, the inner bank weaker. To S there are no ramparts in evidence, but a hedgeline possibly preserves their location. No ditches.

Enclosed Area:
Area 1:   0.82ha.
Total:   0.82ha.

Total Footprint Area:  Noneha.

Ramparts

None

Multi-period Enclosure System:
✗   Problem of probably missing southern bank in regard to any area definition. 0.82ha probably an underestimate.

Ramparts Form a Continuous Circuit:
✗   The whole of the S line is missing and now a hedgeline.
