I think the opinion of the contributors to this thread, generally, accept that these are pieces - I think there are three - of a Neolithic carved stone. It's a Celtic design, with similarities to Irish passage grave art, such as at Knockrea and Carnbane and also to the carved stone in County Covan, at Killycluggin. In these circumstances (and uniquely) would it be possible to lift the Disputed Antiquity tag ?
