Coflein says this of Carnedd Llewelyn’s cairn:
‘Burial cairn, probably Bronze Age, in a prominent position on the summit of Carnedd Llewelyn. Stone built circular cairn, measuring c. 8m in diameter and up to 1.5m in height.‘
So, not the largest cairn you’ll ever see – although no doubt it’s suffered a lot over the years – but then again, being up here, it doesn’t have to be, does it?
