In a pasture on a north-facing hillside, a roughly circular enclosure sits on a low hillock or terrace, its diameter somewhere between sixteen and eighteen metres. The enclosing bank is low and much worn, rising only forty to seventy centimetres on its outer face, but it was carefully built: large stones kerb both its inner and outer edges, and where the bank has degraded most severely, at the north and north-east, a shallow arc of upright stones and boulders marks where the kerb once stood. Dense overgrowth swallows the eastern and southern sections entirely.

The most deliberate feature is the entrance on the western side, where a formal passage was set into the bank. At its inner end, a matching pair of large upright stone slabs flank the opening, which measures roughly 1.2 metres across, and the passage appears to splay or widen outwards towards the exterior, where smaller upright stones continue the facing. This kind of carefully framed entrance, with paired jamb stones, is a feature found in stone-built enclosures across Ireland, and its survival here gives a sense of the original structure's formality. Within the enclosure, the south-east quadrant contains what may be the remains of a rectangular house. Fragments of later field banks and walls cling to the outside of the enclosure on its north-east and south sides, partly engulfed in vegetation, suggesting the site was worked around and over in subsequent centuries. Seán Ó Nualláin recorded it as a stone fort in 1989. About sixty-five metres to the south-west lies a rath, an earthen or stone-banked enclosure of the kind commonly associated with early medieval settlement in Ireland, and roughly 140 metres downslope to the north there is a possible passage tomb. Knocknarae, the great hill with its unexcavated cairn traditionally associated with the legendary queen Méabh, is visible to the east, a reminder of how densely this part of Sligo was used across prehistoric and early historic time.
