The site at Courtballyedmond reveals itself as a cropmark, a phenomenon where buried features such as ditches or banks affect the growth of surface vegetation, producing faint but legible patterns visible in aerial or satellite imagery. What emerges here is the outline of a subcircular or D-shaped enclosure, roughly 60 metres east to west and 55 metres north to south, its form defined by a single fosse, or ditch, running around most of its perimeter, with a notably straight edge along the southern side.

The enclosure sits in a slight fold on a gentle east-facing slope, the kind of modest, sheltered position that was often favoured for early settlement or enclosure in the Irish landscape. It was first reported by Simon Dowling, who identified the cropmark using Google Earth imagery captured on 14 July 2018. The site would almost certainly have remained unrecorded without that combination of dry-season aerial visibility and an attentive observer. Enclosures of this general form are associated in Ireland with a broad range of periods and functions, from early medieval ringforts to prehistoric ceremonial or agricultural boundaries, and without excavation it is not possible to assign this example to any particular era.
