What sets it apart is a combination of subtle engineering and a single weathered stone that shifts the whole interpretation. The interior has been deliberately raised on its southern side to level it against the natural hillslope, a detail that speaks to careful, purposeful construction rather than casual enclosure. At the eastern edge sits a bullaun stone, a large fixed boulder with one or more cup-shaped hollows ground into its surface, objects found almost exclusively in early Christian ecclesiastical contexts across Ireland. That pairing of shaped landscape and ritual stone is what earns the site its classification as an ecclesiastical enclosure rather than a purely defensive one.

The earthwork is oval in plan, measuring roughly 90 metres north to south and 74 metres east to west. It is defined on its south-western to western arc by an earthen bank standing about 1.2 metres high on the interior and 0.9 metres on the exterior, while elsewhere the boundary survives as a scarp reaching up to 1.9 metres. A low ridge crosses the northern half of the interior from east to west, though its function is not fully understood. When Bowman recorded the site in 1934, he described it as a single-ramparted fort on land then belonging to a Mrs Nash, estimating that about one-third of the circuit was still traceable at around three feet high, with the interior sitting roughly one and a half feet above the surrounding field. The 1842 Ordnance Survey six-inch map shows the enclosure as a hachured oval, a cartographic convention used to indicate an earthen bank or raised feature, and it reappears on the 1905 and 1936 editions, by which point only portions of the scarp and bank were being marked.
