Roughly fourteen metres long, eight metres wide, and rising about one and a half metres from the surrounding land, it is large enough to notice but ambiguous enough to puzzle. There is no enclosing fosse, the ditch that typically rings a man-made earthwork and whose spoil would have been used to build it up, which means the usual evidence for deliberate construction is simply absent.

What makes the mound genuinely curious is the question of whether it was made at all, at least in the straightforward sense. The current thinking is that it may be a natural hillock, a slight rise in the land that was then scarped and levelled off at the top, shaping an already-existing feature rather than heaping one up from nothing. That process, modifying the natural landscape with modest but purposeful effort, was not unusual in early medieval Ireland, when slight elevations could serve as gathering points, boundary markers, or platforms for structures that have long since vanished. A second mound sits nearby to the north-west, which raises the possibility that whatever use one served, the other shared it, though the relationship between the two remains unresolved.
