The circular enclosure, roughly 35 metres across, survives as a cropmark, the kind of ghostly impression left in soil and vegetation when buried features such as ditches alter how crops grow above them. Only from altitude does the full shape become legible.

The site sits on a broad spur running northwest to southeast along the southeastern foothills of Carrickbyrne Hill, a position typical of ringforts, the most common type of early medieval settlement in Ireland. These were usually farmsteads enclosed by one or more earthen banks and ditches, occupied roughly between the 6th and 12th centuries. Here, the defining feature is a fosse, a ditch cut into the ground that would originally have helped define and defend the enclosed space. Aerial photography from the mid-twentieth century first revealed the outline, and digital aerial images captured in 2006 confirmed it. Drone photography by Jim Foran in July 2018 added further detail, showing a narrow entrance gap in the fosse on the southeast side, with additional gaps at the south and west.
