The rounded summit, nearly sixty-three metres across, is ringed by an artificial scarp, a deliberately cut or built escarpment that drops roughly a metre on the western side and more than two metres on the eastern edge. That asymmetry is worth pausing over: this is not the even silhouette of a natural drumlin but a landform that someone, at some point, decided to define and remodel.

The site belongs to a broad category of enclosed hilltop features found across Ireland, where a raised perimeter, whether formed by a bank, a ditch, or a scarp like this one, demarcates an interior space for purposes that are not always easy to recover. Here, the interior ground does not flatten but continues to rise toward the centre, where a mound sits at the highest point. The relationship between the enclosing scarp and that central mound is the real puzzle. Over time, stretches of the scarp were absorbed into ordinary field boundaries, the kind of quiet recycling of ancient earthworks that happened across the Irish countryside as later farmers found ready-made walls and divisions in whatever the previous occupants had left behind. The River Moy runs about a hundred metres to the east, close enough that whoever built here would have had both water access and an elevated vantage over the surrounding lowland.
