What gives it away, if you know what to look for, is the logic of its shape: a near-perfect circle roughly 35 metres across, defined by a raised earthen bank and a fosse, the shallow defensive ditch that typically runs along the outside of such enclosures.

This is a rath, the Irish term for a ringfort, a class of monument built and used primarily during the early medieval period, broadly between the fifth and twelfth centuries. Ringforts were the farmsteads of their era, circular enclosures that housed families and their livestock, the bank and fosse providing a degree of protection against cattle raiders rather than any kind of military assault. Thousands survive across Ireland, though rarely in a condition this unexamined. The bank here stands 2.1 metres on the interior face and 2.5 metres on the exterior, dimensions that suggest a reasonably substantial original construction. Along the outer edge of the fosse, a dry-stone wall once reinforced the earthwork; it has since collapsed to a height of just 0.35 metres, and the loose stone it has shed litters the ditch around it. The survey, compiled by Denis Power and uploaded in August 2011, notes that the bank is very heavily masked by overgrowth and that the interior is completely covered by dense vegetation.

Access to the site, such as it is, runs only from the northwest, the single point where the overgrowth has not entirely closed things off. The enclosure sits on a gentle east-facing slope in what is otherwise open pasture, so the earthwork itself is visible in outline from a distance, even if getting close enough to read its details requires persistence. The collapsed wall and the stone-filled fosse are the clearest physical features still legible on the ground. There is no infrastructure here, no signage or managed path, and the dense interior growth means that little of what lies within the bank can currently be assessed without clearance work.
