The southwest side of the enclosure needed no rampart; the drop into the valley below served that purpose. What the builders did construct, a single earthen bank curving around the remaining arc, has largely disappeared into the pasture around it, worn down over centuries until only a low swell in the ground marks where it once stood.

The fort was roughly circular, about 38 metres across, and belongs to a class of enclosure known from hundreds of sites across Ireland, most of them dating from the early medieval period. These ringforts, raised platforms or banked enclosures that once protected farmsteads and their inhabitants, are so numerous in the Irish landscape that their individual stories are easily overlooked. This one was recorded in 1934 by Bowman, who noted it as a levelled fort in the land of a Jerh. Linehan, describing it as single-ramparted with a diameter of around 30 yards. By then it was already gone in any meaningful structural sense. A 1937 Ordnance Survey map still shows the penannular, or nearly complete ring, outline as a hachured scarp running from west around to the southeast, with the cliff edge forming the southwestern boundary. Beneath what remains of the interior, a souterrain has been recorded. These underground stone-lined passages, typically associated with early medieval settlement, were used for storage or refuge, and their presence often signals that a site was once more substantial than its surface appearance now suggests.

The fort sits in farmland, and the earthwork that survives amounts to little more than a slight rise of half a metre on the outer face. What rewards a visit, if the land permits access, is the relationship between the earthwork and its setting: standing at the northwestern arc of the old bank, the stream valley drops away sharply to the south, and the logic of the original choice of ground becomes immediately clear.
