By 1837, the Ordnance Survey's six-inch map had already marked it as a circular enclosure planted with trees and labelled it simply "Fort", a designation that suggests the cartographers recognised its antiquity even then, even as the site was already becoming absorbed into the landscape around it.

The monument is a ringfort, a type of enclosed farmstead typically dating from the early medieval period, roughly the fifth to the twelfth centuries, when such earthen or stone-banked enclosures served as the basic unit of rural settlement across Ireland. This particular example, sited on a terrace adjacent to a stream, was recorded in 1986 as a small circular structure with a diameter of around 22 metres, its perimeter defined partly by the remnants of an earthen and stone bank running from the south-west to north-north-west, and partly by a steep irregular scarp completing the circuit. At that point it was already obscured beneath a dense thicket of elder, hawthorn, and blackthorn. When surveyors returned in 1998, the vegetation had not thinned. More notably, the monument's outline appeared to have shifted: rather than circular, the surviving earthworks suggested a more rectangular form, measuring roughly 28 metres east-north-east to west-south-west and 16 metres across. The original bank had gone entirely, reduced to nothing more than a scarp in the ground.

What the site illustrates, quietly, is how these monuments erode not in dramatic collapses but in long, incremental losses. A bank becomes a low ridge, a ridge becomes a slope, a slope becomes indistinguishable from the surrounding field. The encroaching scrub that hides the site also, in a sense, preserves what little geometry remains.
