It is not the bank itself, not a wall in the conventional sense, but something between the two, a secondary layer of material whose precise purpose remains open to interpretation. Combined with the slightly raised interior on the downhill side, levelled deliberately to compensate for the natural gradient of the south-south-east-facing slope, the site gives the impression of a structure whose builders were solving problems as much as following a template.

The rath, to use the Irish term for this class of monument, is broadly circular, measuring thirty-four metres north to south and thirty-two metres east to west. An earthen bank stands to a height of around 1.7 metres, and an external fosse, a defensive ditch, runs along the western to eastern arc of the enclosure. The entrance, 3.4 metres wide, faces south-east. At the centre of the interior is a souterrain, an underground stone-lined passage or chamber of a type commonly associated with early medieval settlement in Ireland, typically interpreted as a place of storage, refuge, or both. Ringforts of this kind were most often the enclosed farmsteads of prosperous farming families during the early medieval period, roughly the fifth to twelfth centuries, and tens of thousands of them survive across the Irish landscape in varying states of preservation. The combination here of an earthen bank, an outer ditch, an internal stone dump, a carefully levelled floor, and a subterranean chamber suggests a site whose occupants invested considerable effort in making it functional and defensible.
