These 5 stones all lie on the ridge which leads from Cwm Pennant up to Pen-y-Garnedd at SJ 0410 3092 where there is a round barrow (cairn). All are listed by the Clwyd Powys Archaeological Trust as being from the bronze age. It seems likely that they marked the route up to Pen-y-Garnedd which would also be a good route to get over to the stone circle and row at Rhos y Beddau in the Disgynfa valley.
Some of the stones are pretty small but they are all quite slim and have been set upright in the earth. I can't see any logic to the directions in which they have been set. The ground is grassy with almost no other exposed stones visible.
