Twenty-five metres across, it is defined by a low bank of earth and stone, roughly 1.7 metres wide, that rises only 35 centimetres above the interior ground level while standing 80 centimetres proud of the exterior. What makes it quietly puzzling is the absence of any clear entrance feature, the usual gap or causeway that would tell you how people passed in and out. Without that detail, the enclosure sits there, closed and uncommitted, declining to explain itself.

Enclosures of this kind are broadly common in the Irish landscape, often associated with early medieval settlement or agricultural activity, but they resist easy categorisation when the diagnostic details are missing or worn away. A ringfort, for instance, a circular enclosure typically used as a defended farmstead between roughly the fifth and twelfth centuries, would normally show a more pronounced bank and a clear fosse, the surrounding ditch that provided the upcast material for the bank's construction. Here there is no visible fosse, which either means it was never dug, that the bank was built differently, or simply that time and the slope have obscured it. A ringfort does sit nearby to the east, recorded separately, and the proximity of the two sites suggests this patch of upland was meaningful to the people who shaped it, though whether the two enclosures were contemporary or centuries apart in their use is unknown. Researcher Margaret Stout noted the site as early as 1984, and it was later incorporated into the archaeological inventory of North Tipperary compiled by Jean Farrelly and Caimin O'Brien.
