1. Burial cairn, situated within open moorland, above and to the NE of the Afon Twrch. It is circular on plan and measures about 8.5m in diameter and up to 0.4m in height. There is an exposed cist or chamber in the centre of the cairn, measuring about 1.2m from ESE to WNW by 0.9m transversely and 0.6m in depth within several large orthostats. A linear hollow extends from the open ESE end of the cist to the edge of the cairn material; this may represent antiquarian investigation or an original passage.
