At ground level there is nothing to see; the site has been levelled entirely, leaving no visible trace in the grass. But aerial photography tells a different story. Looking down, the buried outline of a fosse, the encircling ditch that once defined a ringfort's boundary, shows up as a cropmark, a subtle variation in vegetation growth caused by the soil disturbance below. More striking still, a second concentric cropmark marks the line of a narrower outer fosse, suggesting this was a double-ditched enclosure, a feature generally associated with sites of some local importance.

Ordnance Survey mapping charts the slow disappearance of this place across nearly a century. The 1842 six-inch map records a circular enclosure roughly thirty metres in diameter, at that point still planted with trees, a common fate for ringforts that had survived into the modern era by being treated as inconvenient ground rather than cleared outright. By 1905 and again in 1937, the same maps show a hachured circular raised area, slightly smaller at around twenty-five metres, indicating the earthwork was still perceptible as a low mound even as it shrank. At some point after that, levelling finished the job. What had been a rath, the Irish term for a ringfort, typically a circular area enclosed by one or more earthen banks and ditches and used as a farmstead during the early medieval period, was reduced to nothing the eye can detect. Notably, a second circular enclosure sits in the same field, roughly seventy metres to the north-west, suggesting this corner of the Castle Kevin demesne once held a concentration of early settlement activity rather than a single isolated site.
