Historic England summarises this impressive monument thus:
“A cairn situated on the flat crest of the south-east spur of Royal Hill at 395.0m OD being a mound of partly-turf-covered large stones with a depression in the centre. Its diameter is 16.0m and its maximum height 1.6m.”
Clearly, not a site to miss when visiting the other excellent cairns/cists in the locale of Royal Hill.
