Ringforts, which were the enclosed farmsteads of early Christian Ireland, typically consist of a circular bank defining a domestic space within; this one is univallate, meaning it has a single enclosing bank rather than the doubled or tripled rings found at higher-status sites. What makes it worth pausing over is the scale and condition of its outer fosse, the defensive ditch that runs around the outside of the bank. At two and a half metres deep and nearly four metres wide, flat-bottomed and steep-sided, it is an unusually well-preserved example, though there is some suggestion it may have been recut at some point after its original construction.

The internal diameter of the enclosed space is forty metres, and the bank of earth and stone is best preserved along its northern arc, where it still reaches roughly eighty centimetres in height and five metres in width. A causewayed entrance, a raised crossing over the fosse, survives on the north-north-east side. These details were recorded by Healy in 1975, and the site was later compiled by Geraldine Stout and updated by Christine Baker. The ringfort sits approximately thirty metres west of an access road built in connection with the proposed Thornton Hall prison development, and drainage work along an east-west field boundary extending south of the monument has altered the surrounding landscape in ways that bear on how the site reads today.

The interior, by most accounts, is heavily overgrown with trees and brambles, with one exception: the eastern quadrant appears to be relatively clear, most likely due to extensive burrowing, tentatively attributed to badgers, whose earthworks can be as disruptive to a site as any drainage scheme. The monument sits in working pasture, so access requires landowner permission, and the surrounding fields give little visual warning of what lies within the vegetation. The fosse is best appreciated from the northern side, where the bank above it remains most legible. Winter or early spring, when the bramble growth is at its lowest, would offer the clearest sense of the enclosure's original geometry.
