An L-shaped length of banking perched on the edge of the cutting of the river Usk, above its west bank, may represent the only surviving traces of a rectangular building, the east side and north end walls of which having collapsed into the cutting through erosion. Overall it measures 6m long (N-S) by 3m wide at the south end. The stony bank is 1.2m wide and 0.3m high.
