A rath, or earthen ringfort, once stood here: one of the thousands of roughly circular enclosures built across Ireland during the early medieval period, typically serving as defended farmsteads for a single family and their livestock. This one has been so thoroughly reduced by agriculture and time that what remains is less a monument than a faint argument in the landscape, a low earthen bank still tracing part of the circuit, dropping just over half a metre on its interior face and rising to about one and a half metres on the exterior, with a barely perceptible rise completing the eastern arc.

The site was already legible enough in 1842 to appear on the Ordnance Survey six-inch map, marked with the hachured lines cartographers used to indicate an earthwork enclosure. Its diameter at that point, or at least as recorded in the twentieth century, measured around 34.5 metres across. By 1934, when a researcher named Bowman documented it, the fort was described as practically levelled, a single-ramparted enclosure of roughly 41 yards in diameter sitting on land then belonging to a D. MacSweeney. The phrasing suggests that even then its condition was considered notably poor, which makes the survival of any earthwork at all across the subsequent decades quietly remarkable. What the 1842 map captured and what Bowman saw in the 1930s were already two stages of the same slow erasure, and the process has continued since.
