'A round cairn or kerb circle situated near the summit of Mynydd Llangyndeyrn ridge, to the east of Crwbin, which measures 10m in diameter and has a kerb of stones c 0.3m high; there are the possible remains of a central cist represented by two stones c 1m long set on edge. Note that the prominent standing stone in the centre is a `fake? ? it is one of the two slabs that once formed the central cist and has been set upright relatively recently.'
