Summary

Poorly preserved level terrain hilfort sited on an escarpment edge above the River Wye 0.2km away at Felin-fach. To the E for 200m is rising ground to the large Hillis Camp (Atlas No 1316). Today the site appears as a shield-shaped enclosure, 60m N-S by 45m of 0.4ha internal area, the flat side facing to S. Earlier mapping (OS County series Brecknock. XXVIII.3 1887 referred to by RCAHMW Coflein) shows this to be only the N part of an elongated enclosure at least 120m N-S, so much has been lost. The present flattened S side corresponds with a field boundary. Surrounding slopes of present enclosure moderate to strong to N, S and W and moderate to E. Site now defined by a natural scarp on W with rock outcrops in places. Rampart best on NE where it is an earth and stone bank with ditch. To S plough damaged has masked features. Likely position of entrance on N between the curving bank and the natural escarpment, but plough damage has again obscured details. No interior structures visible. Under improved pasture. On 1st Ed. OS map (1887). Minimal investigations, undated.
