It measures roughly seven metres across, defined by a modest bank of earth and stone standing between twenty centimetres and forty-five centimetres high on the interior. A gap on the northern side appears to be of modern origin, probably a later intrusion rather than an original entrance. The structure sits just off the hillock's summit, which is itself an unremarkable feature in the landscape, and yet that positioning, slightly below the crest rather than directly on top of it, is the kind of deliberate choice that tends to mean something.

Archaeologists working from field evidence have provisionally identified it as a house, the remains of a small subcircular dwelling of indeterminate date. But the classification carries a notable caveat: the possibility that this is instead a barrow, a burial mound, cannot be entirely ruled out. The two uses are not always easy to separate when a structure has been reduced over centuries to a low earthen ring. Roughly a hundred metres to the north-northeast sits a ringfort, a type of enclosed farmstead common across early medieval Ireland, and the spatial relationship between the two features raises the question of whether they were ever connected in use or simply accumulated independently in the same stretch of ground over a long period. Without excavation, the uncertainty holds.
