Only its eastern edge gives any real indication of what it once was, where a cluster of larger boulders and what may be an external stone setting poke through the peat. The rest of the structure, a roughly circular arrangement measuring just under eleven metres north to south and a little over twelve metres east to west, survives as a low, collapsed wall no more than forty centimetres high. It is the kind of feature that reads clearly enough on a site plan but would be easy to walk past without knowing what to look for.

The enclosure sits in mountain grazing land at Ballynabrocky in County Wicklow, a landscape shaped over millennia by a combination of human activity and the gradual accumulation of blanket bog, the dense, wet peat that forms in high-rainfall upland areas and can preserve and conceal structural remains in roughly equal measure. The wall itself, around one and a half metres wide, appears to have been built largely from small boulders, with the larger stones concentrated to the east. What function the enclosure originally served is not recorded; in an upland context like this, such circular stone-walled features can relate to early settlement, agricultural use, or other purposes now difficult to untangle from the ground surface alone. The peat cover makes interpretation harder still, obscuring most of the enclosing element and leaving only fragments visible at the surface.
