On the east-facing slopes of Cwm Dringarth, above the Ystradfellte Reservoir, on the north bank of a minor stream, is a grassy rectangular platform. The terrace measures 7m (WNW-ESE) by 4m, is cut back to 1.3m deep and built out to 1.1m high. The upper scarp of the platform extends along each side of the terrace as 2.5m long grassy banks, especially visible on the north side. The platform is otherwise featureless, overgrown with light vegetation.
