Roughly oval in shape, measuring about 32 metres from north-east to south-west and 29 metres across, it is defined by a slight scarp, a low earthen edge, that is best preserved on the south-east side where it still rises to around 0.7 metres. That modest lip is the most visible trace of what survives here, a subcircular embanked enclosure of the kind that appears across Ireland but rarely announces itself loudly.

The site was recorded as a circular embanked enclosure on the Ordnance Survey six-inch map of 1839, with an external diameter of around 30 metres. By the time the next significant mapping revision came around in 1940, the feature was represented differently, as an arc of hachures, the short lines surveyors use to indicate slope or earthwork edges, running from east through south to west, with the overall diameter recorded at approximately 40 metres. The variation between those two depictions reflects both the difficulty of mapping subtle earthworks from the ground and the gradual erosion that alters such features over generations. Directly to the north lies a ringfort, a type of enclosed farmstead common in early medieval Ireland, typically consisting of a circular bank and ditch surrounding a domestic settlement. The two features sit immediately adjacent to one another, which raises questions about whether they were ever related in function or date, though the available evidence does not settle the matter.
