SAM No CN358
Two large cairns, probably dating to the Bronze Age and situated within op0en moorland on the summit of Y Garn. The stone built cairns are circular on plan and measure about 10m in diameter and up to about 2m in height. The cairns have both been disturbed in the past, with the construction of drystone shelters around hollows dug into the centres. Cairn A is the easternmost cairn (SH551526) and Cairn B is the westernmost of the pair.
