A roughly circular cairn of 51-54 feet in diameter adorns the top of Cefn Gelligaer. A damaged burial cist is in the centre of the cairn beneath a modern OS triangulation pillar. Records from the 18th and 19th centuries mention 3 parallel cists containing cremated remains and pottery urns, but there is no evidence of this today.
