What makes it worth a second look is not its size, which is modest at around 25 by 31 metres, but the layers of human engineering still visible in the grass. An earthen bank, standing nearly two metres high in places, traces the enclosure's perimeter. Outside it, a fosse, essentially a defensive ditch cut into the ground, runs from the east around to the northwest, adding a further barrier to the boundary. A possible outer bank curves from the east-southeast to the north-northwest, though much of it has been absorbed into the existing field fence system over the centuries, the kind of quiet absorption that happens when farming families find a ready-made boundary and simply keep using it.

This type of site is known as a rath, the earthwork variant of the ringfort, the most common monument type in the Irish landscape. Ringforts were typically built during the early medieval period, roughly between the fifth and twelfth centuries, as enclosed farmsteads for a single family or small community. They are not military fortifications in any grand sense, but working homesteads whose banks and ditches provided security against livestock theft and defined social territory. The break in the bank to the northeast, about 2.2 metres wide, would have served as the original entrance. More intriguing is the souterrain recorded in the interior. A souterrain is an underground stone-lined passage or chamber, built beneath the floor of the enclosure, used variously for storage, refuge, or both. Their presence inside a rath is relatively common but always suggests a domestic life of some complexity, one where people stored provisions carefully and perhaps had reason to hide.
