The feature is D-shaped, roughly 36 metres along its longer axis, and defined not by dramatic earthworks but by a low bank, a hedge line, and a quiet change in the ground level that most people would walk across without a second thought. There is no visible fosse, the term for the defensive ditch typically accompanying an enclosure of this kind, and no clear evidence of an original entrance. What survives is, in effect, half a monument.

The enclosure appears on the 1834 edition of the Ordnance Survey six-inch map, where a road or path is shown curving around its southeastern to northwestern arc, suggesting that the local landscape had already accommodated itself to the shape of whatever was there. By the time the 1907 edition was produced, the feature was recorded as distinctly D-shaped, implying that the northeastern portion had already been lost, cut off by the straight field bank that still truncates that side of the monument today. Earthwork enclosures of this general type are commonly referred to as ring-forts or raths, the most widespread class of archaeological monument in Ireland, typically dating from the early medieval period roughly between the fifth and twelfth centuries, and used as enclosed farmsteads rather than military fortifications in any modern sense. The drumlin ridge setting is characteristic; elevated ground offered drainage, visibility, and a degree of natural defence without requiring elaborate construction.
