It does not appear on the Ordnance Survey's six-inch map from 1837, which means that for much of the period when Irish landscapes were being systematically recorded and named, this structure went unnoticed, or was simply not considered worth marking down.

What survives is a cashel, a type of early medieval ringfort built from stone rather than earthen banks. The enclosure is roughly twenty metres across, defined by an irregular bank of local limestone rubble some four and a half metres wide and half a metre high. Unlike earthwork ringforts, cashels typically lack a fosse, the external ditch that accompanies their earthen counterparts, and no trace of one is visible here. The original entrance has also been lost, leaving no obvious point of arrival or departure. Cashels of this kind are generally associated with early medieval farming settlements, the enclosed space providing a defensible or at least defined area for a household and its livestock. This one sits unassumingly in the landscape, its walls barely raising themselves above the surrounding ground, overgrown now with thorn bushes and briars that have colonised the bank and blurred whatever shape it once presented to a visitor approaching across the hill.
