It measures roughly 43 metres from north to south and 34 metres from east to west, with the straight side running along the west. That flat western edge is what marks it out. Most ringforts, the circular or oval enclosed settlements built across Ireland roughly between the early medieval period and the Norman arrival, follow a more regular curve all the way around. A flat side is less common, and its presence here gives the earthwork an asymmetry that raises quiet questions.

The site appears on the 1834 edition of the Ordnance Survey six-inch map, where it is labelled in gothic lettering as a "fort", the conventional cartographic shorthand of the time for an earthwork enclosure of presumed early medieval origin. By the 1907 edition it is shown again, rendered in hachures, the short lines used by Victorian and Edwardian cartographers to suggest relief and slope. The survival of the feature across nearly two centuries of mapping suggests it was substantial enough to remain legible in the field even as the surrounding land was improved and divided. Today the scarp, the step in the ground formed by the collapsed or eroded bank, is best preserved along the south to south-west arc, where it still stands roughly two metres high and two metres wide at its base, incorporated into the living boundary of a modern field.
