What the Ordnance Survey once mapped with enough confidence to mark as a distinct oval, roughly fifty metres north to south and thirty-five metres east to west, has since retreated so far into the landscape that a visitor standing at its northern edge would be looking for a barely discernible rise in the ground. That small swell in the grass is, by most measures, all that remains.

Enclosures of this kind, typically defined by an earthen bank or a stone wall forming a roughly circular or oval boundary, are among the most common ancient monument types in Ireland, and among the least understood. They served any number of purposes across different periods, from agricultural enclosures to settlement boundaries, and their age is often difficult to establish without excavation. At Curragh, a field bank running from the north-east to the south-east of the site may preserve some fragment of the original enclosing element, folded now into the ordinary agricultural fabric of the hillside. The Ordnance Survey six-inch maps, surveyed in the nineteenth century, caught the monument at a moment when it was still legible enough to record, but the ground has since done what ground tends to do over time.
