It is easy enough to pass without registering what it is, but the geometry of the place repays attention. A raised platform roughly 28 metres in diameter is enclosed by an earthen bank that grows noticeably more substantial as you move from the north-east side around to the south-west, where the exterior face stands nearly 2.75 metres high. That asymmetry, the result of the ridge's natural contours being worked to maximum defensive advantage, gives the monument a lopsided solidity that feels deliberate rather than merely weathered.

This is a rath, the Irish term for a ringfort, the most common type of early medieval settlement monument in the country. Raths were typically the enclosed farmsteads of relatively prosperous farming families, in use roughly between the fifth and twelfth centuries, though many were built on sites with much older associations. The bank here, between 4.5 and 6.3 metres wide depending on where you measure, would originally have been topped by a wooden palisade or thorny hedge. Just outside the bank on the west to north-west side, a shallow depression about 2 metres wide may be the ghost of a fosse, the external ditch that would have added another layer of enclosure. A gap of about 1.4 metres on the western side could be an original entrance, though whether it was always an opening or is simply a later breach in the bank is not settled. Adding to the ambiguity is a low, irregularly shaped raised area within the north-eastern portion of the interior, measuring roughly 13.5 metres east to west and 11.5 metres north to south, rising only 30 to 60 centimetres above the platform floor. Its function and age remain unknown, and it sits there without obvious explanation, the kind of feature that invites speculation without rewarding it with certainty.
