That much is certain. Who built it, and why, is less clear, which is part of what makes it quietly compelling. The structure sits at the summit of a hill with wide views in nearly every direction, north-east over open expanses of bog, east towards Lough Roe, and south-west across a ridge of grassland. Positioning like that is rarely accidental.

The mound itself is modest in scale, a low, flat-topped subcircular rise of earth and stone roughly ten metres in diameter. It stands about 0.45 metres high at its southern edge and rises to approximately 1.4 metres on the western and northern sides, where a steeper scarp or slope gradually merges with the natural hillside. The southern and south-western edges are defined by a low scarp, the kind of subtle earthwork that is easy to walk past without registering what you are looking at. A straight field wall running north to south crosses the eastern edge, and remnants of an older stone wall survive along the western and north-western perimeter of the mound, suggesting the site was at some stage incorporated into a working agricultural landscape. Mounds of this type, placed on elevated ground with commanding sightlines, appear across Ireland in various periods and contexts, from prehistoric burial cairns to early medieval territorial markers, though the notes attached to this one stop short of assigning it a definitive function or date.
