The more southerly of two cairns (see also Nprn309812), set c.18m apart between two lines of outcropping, 14m in diameter and 1.3m high, disturbed by the construction of shelters from its fabric.
It is suggested that the ruin of a third cairn, further to the N, revealed a cist, giving rise to the name 'Cistfaen'.

Remains of two burial cairns, probably dating to the Bronze Age, on the South-facing side of the summit of Cistfaen. Both are roughly circular on plan - the northernmost cairn (A) measures about 8.5m in diameter and up to 0.6m in height; the southernmost (B) measures about 13.5m in diameter and up to 1.1m in height.
