A small circular enclosure, somewhere between ten and fifteen metres across, was recorded on the Ordnance Survey's six-inch map of 1838, sitting prominently at the break of slope on the steeply falling north-east side of the ridge, with wide views in most directions. It does not appear on any later map edition, and today there is no visible trace of it whatsoever at ground level.

The enclosure belongs to a broad category of circular earthworks found across Ireland, ranging from prehistoric ringforts to early medieval farmsteads enclosed by a raised bank and ditch, known as a ráth or ringfort. What this particular example was, who built it, or when it was in use, the surviving record does not say. What the 1838 mapping does confirm is that it was detectable at that point, at least to a surveyor's eye, though clearly not dramatically so given how thoroughly it has since vanished. The site commands a natural hillock-like rise to its south-west, and its prominent, exposed position on the ridge is the kind of placement seen repeatedly in Irish enclosures of various periods, where elevation conveyed both practical oversight of surrounding land and, perhaps, a degree of social visibility.

The complete absence of surface remains today suggests the enclosure was either very slight to begin with or was levelled sometime after the mid-nineteenth century, possibly through agricultural improvement or simple attrition by livestock and ploughing. Pasture now covers the spot. The ridge itself still offers the good views noted when the feature was first mapped, even if the thing that once made the location worth recording has long since disappeared into the grass.
