The structure itself was never large, measuring only four metres in diameter, which is roughly the footprint of a generous garden shed. What makes it quietly worth attention is the precision still legible in the ruin: a drystone wall, built without mortar by laying stones carefully against one another, has largely tumbled and scattered down the surrounding slopes, yet the logic of the original building remains readable in what little is left standing.

The entrance, set into the north-eastern arc of the circle, was marked on either side by upright slabs. One of these, measuring roughly half a metre wide and twenty centimetres thick and standing to a height of about seventy centimetres, still sits at right angles to the line of the perimeter wall, functioning as a kind of door jamb in stone. The corresponding slab on the opposite side of the entrance has fallen. Together, the gap they defined was eighty centimetres across, just wide enough to enter stooped. This type of small drystone circular structure is found across Ireland, typically associated with early medieval settlement or pastoral activity, where a family or a herder might have occupied a modest enclosure alongside an outer boundary, the whole arrangement suggesting a working landscape rather than a ceremonial one.

The site sits within a wider enclosure, suggesting it was not a solitary feature but part of a small cluster of remains at Ballynacarriga. The scattered wall material on the slopes outside the perimeter gives a reasonable sense of how much of the original fabric has migrated downhill over centuries, a reminder that what survives above ground is often only the most stubborn fraction of what once stood.
