Remains of a large burial cairn on Moel yr Eglwys, the highest summit of the Arenig Fawr ridge. The site is a Scheduled Ancient Monument. Stone built and circular in shape, the cairn measures some 1.5m in height. Its edge is marked by a low kerb, except on the east side, and the kerb measures a maximum of 0.3m tall and is 12m in diameter. The cairn material has spread beyond the original circumference and now measures some 15m in diameter - the material has been remodelled to include an Ordnance Survey triangulation pillar, a World War II United States Air Force memorial and two walkers' shelters.
