A round barrow is located on sloping ground on a southwest-facing spur above Nant Mawr at 440m above OD and about 20m from the north side of the valley cutting.
The stony mound of small to medium grade stones consolidated with light vegetation measures 12m in diameter and rises to 1.5m high. An edge set slab on its east side suggests a possible kerb otherwise obscured. The centre of the mound has been dug out by a trench cut into it from the south side to a depth of 0.8m, exposing its loose rubble core and leaving behind it a trail of robber debris 6m long. No structural features were seen in the trench.
