I must confess the existence of this extensive grouping of cairns to the west of the hillfort Craig y Dinas came as a complete surprise to me, nothing being shown on either the 1:25K or 1:50K OS map. It would appear there are also numerous hut circles /settlement features in the vicinity, too.
The relevant Coflein record is apparently based upon an oblique aerial image, the size of the main cairn here (at co-ordinates I’ve given for the site) clearly suggestive of a prehistoric origin, as opposed to later clearance. Hopefully the ground level detail I’ve been able to capture collectively makes a strong supporting case for the existence of some ritual monuments set within clearance piles of undetermined age.
According to Coflein the main round cairn is:
“Stone cairn, c.9m diameter, visible on oblique cover. Probable prehist. ritual monument. Part of larger cairnfield.”
As regards the cairnfield:
“Extensive cairnfield c.169mx173m (mapped) which can be traced for some 530m N/S. Likely Prehist. origins mixed with U med clearance. Open pasture gently slopes to SW.”
Note also the placement of a very large cairn near of the summit of Moelfre to the approx north-east.....
