What makes it worth pausing over is how little of it now remains above the surface, and how much of what does remain blends almost seamlessly into the natural contours of the hillside. The arc, roughly twenty-four metres across, is partly defined by a natural scarp rather than purely by human construction, with a low rise and a shallow external depression of only about a quarter of a metre along its eastern side. The interior is level.

By 1904, when the Ordnance Survey recorded the feature on its six-inch map, the earthwork was shown as a hachured semicircular arc of around fifteen metres running north to south, a cartographic convention indicating an earthen bank or mound with some visible relief. By the time the same area was resurveyed in 1938, that confident solid line had become a broken one, suggesting the feature had degraded further or that surveyors were less certain of what they were seeing. Whether the arc was ever a complete enclosure, a ringfort of the kind once common across Cork and the wider Irish countryside, or something else entirely, the surviving evidence does not say with confidence. Ringforts, roughly circular enclosures defined by one or more earthen banks and ditches, were typically built between the early medieval period and around the twelfth century and served as farmsteads for single family groups. This earthwork may belong to that tradition, though the partial survival and the natural scarp complicating its outline leave the question open.
