Remains of a ring barrow, measuring c. 16m in diameter. The bank measures c. 4.0m in width and 0.5m in height. A curvilinear area of reed growth outside the south perimeter of the earthwork suggests the presence of a ditch. The monument has spatial association with two cairns (NPRNS 304473 and 402128) on the summit of Mynydd Castlebythe.
