The site is a ringfort, one of the thousands of roughly circular earthwork enclosures built across Ireland during the early medieval period, typically as farmsteads or defended homesteads. What makes this one quietly unusual is the layering: built into the inner face of its western bank is the outline of a horseshoe-shaped hut, open to the west, and the interior of the enclosure was later reused as a children's burial ground.

The 1986 Castleisland District Archaeological Survey described the enclosure as sitting on top of a hill in an area of pasture. The horseshoe-shaped hut, pressed against the inner face of the bank, would have been a simple structure using the existing earthwork as part of its rear wall, a practical approach common in early medieval Ireland. Children's burial grounds of this kind, known in Irish as cillíní, were used from roughly the medieval period into the twentieth century for infants who had died before baptism and were therefore, under Catholic doctrine of the time, excluded from consecrated ground. Ringforts and other ancient enclosures were frequently chosen for these burials, partly because they already existed outside the bounds of the parish churchyard, and partly, perhaps, because such liminal places carried their own quiet significance. The presence of a cillín here adds another layer of use to a structure that may already have been several centuries old when the first small graves were dug.

The hut itself remains tentative in the archaeological record. A circular feature on a revised edition Ordnance Survey six-inch map was identified as a possible match, and an aerial image taken in February 2021 shows its outline still visible from above, a faint arc in the pasture grass that rewards a careful eye rather than an obvious inspection.
