A slight rise in the pasture ground, a gentle scarping where the land drops away to the west, and that is more or less the sum of it. Yet the Ordnance Survey mapped it faithfully three times over the course of nearly a century, in 1842, 1904, and again in 1936, each time recording a hachured circular enclosure of roughly fifty metres in diameter. A ringfort, or rath, is the remains of an enclosed farmstead typical of early medieval Ireland, usually defined by one or more earthen banks and ditches, and this one sat on a west-facing slope with extensive views in all directions, the kind of position that made practical sense both for watching livestock and for keeping an eye on whoever might be approaching.

By the time the surveyor Broker noted it in 1937, it was already one of four ringforts recorded within the same townland, which points to a patch of land that was well settled and intensively farmed during the early medieval period. The earthworks themselves have since been levelled, most likely by agricultural activity over the intervening decades, and what the maps once drew as a confident circular enclosure has been reduced to that barely perceptible change in gradient on the downslope side. The gap between the 1936 mapping and Broker's own notes from the following year suggests the levelling may have happened in stages, or that ground-level observation and cartographic convention were already telling slightly different stories about the same feature.
