The monument comprises the remains of a round platform cairn, probably dating to the Bronze Age (c.2300 BC - 800 BC) and measures 6.4m in diameter and stands to a height of 0.5m. Along its southern edge, the heap of stones making up the body of the cairn is held in place by a kerb of three upright slabs of stone about 0.3m in height.
