The enclosure itself, a roughly circular earthwork some forty metres across, was levelled in 1983, and the land has been in tillage since. What remains is a saucer-shaped hollow in the ground and a slight rise to the south where the bank once ran, a kind of topographical echo of something that took centuries to accumulate and a single season to remove.

A ringfort, sometimes called a rath, is the most common monument type in the Irish landscape, a circular enclosure defined by one or more earthen banks and ditches, typically used as a farmstead during the early medieval period. This one was substantial enough to have warranted three concentric banks, which would have placed it at the more elaborate end of the scale. It appeared on Ordnance Survey six-inch maps in 1842, 1905, and 1937, each time rendered as a hachured circle, the standard cartographic shorthand for an earthwork enclosure. For well over a century, then, it was a recognised feature of the local landscape, sitting on a gentle north-facing slope above the Awbeg River. Aerial photographs taken in 1984 and 1989 recorded it in different registers: one set captured soilmarks revealing three concentric banks, the other showed cropmarks of three concentric fosses, the ditches that would have separated those banks. Cropmarks and soilmarks of this kind appear when buried or levelled features affect how crops grow or how soil retains moisture, making archaeology visible from the air long after it has disappeared at ground level.

The timing is notable. The monument showed up clearly in aerial survey in both 1984 and 1989, yet local information indicates it was levelled in 1983. The aerial evidence, by revealing what lay beneath the surface even after the banks were gone, documented a site that had already been destroyed. The Awbeg River, which the original enclosure overlooked to the north-east, still runs through the valley below. The field does not.
