Small, nearly circular, univallate contour enclosure located on small knoll rising to almost l40m O.D. on the W edge of the flood plain of the River Usk, 0.7km N of Tal-y-bont ar Wysg. Near present Brecknock and Abergavenny Canal. Gentle slopes on S and W, more steeply on N and E. Overlooked on W. Measures c. 130m NW-SE by 110m with internal area c. 0.8ha and barely visible on site, but clear from air and showing as an earthwork with parching in air photographs by Chris Musson 1989. Ramparts originally c. 20m across, now virtually destroyed and ditch filled-in. Suggested by CPAT (HER) as bivallate and shows as patches of degraded sandstone. On SE possibly another ploughed-down low bank to form a broad glacial channel NE-SW. To W broad stream gully forms outer defence and possible that the natural scarp above this has been modified to incorporate this natural feature into the defences. Possible S entrance gap. Under improved pasture. Minimal investigations, undated.
