What we know of it comes entirely from the air: a cropmark, photographed in July 1989, showing the faint outline of a fosse, the ditch that would once have defined the boundary of a roughly circular enclosure about thirty metres across.

Cropmarks appear when buried features, ditches, walls, or pits, affect how crops or grass grow above them. A filled-in ditch retains more moisture than the surrounding soil, so the vegetation directly overhead tends to grow taller or stay greener longer, producing a visible discolouration when seen from above at the right time of year. The photograph from 1989 caught this enclosure in enough detail to suggest not just the outer fosse but also a possible internal division running on an east-west axis, and a single small dark patch, described as a macula, in the northern half of the interior. That macula might indicate a pit, a post-hole, or some other buried feature, though without excavation it is impossible to say. Enclosures of this general type and scale in Ireland are often associated with early medieval settlement, the ringfort being the most familiar form, a defended farmstead enclosed by an earthen bank and ditch. Whether that is what lies here is unresolved.

The site has no visible surface expression, no mound, no earthwork, no hollow in the ground. It exists, for now, as a shape preserved in subsoil and in a single aerial photograph taken more than three decades ago.
