A row of boulders, set against a low scarp barely half a metre high, curves gently from west through north to north-east. From the ground, it reads as almost nothing. From the air, the faint arc resolves into something that looks, at least at first glance, like a circular enclosure, the kind of feature that in Irish archaeology typically signals early settlement or land management activity stretching back centuries or even millennia.

The problem is that it probably is not one. The site does not appear on any edition of the Ordnance Survey six-inch maps, which were compiled with considerable thoroughness across the nineteenth and early twentieth centuries and which tend to capture earthworks that had any local visibility or reputation. The aerial photograph that prompted the classification shows a possible enclosure, but the surface evidence, those curving boulders revetting the scarp, points more plausibly to a field boundary, the last surviving fragment of a division that once organised this stretch of farmland. Revetment here means the boulders were used to reinforce or face the edge of the low bank, a practical technique associated with agricultural rather than ceremonial or defensive construction. In short, what looks from above like an ancient ring feature may simply be the residue of someone organising a hillside field, and even that remnant is now largely gone.
