It measures roughly thirty metres in diameter, and everything known about it comes not from excavation or fieldwork but from satellite imagery, the kind that has quietly transformed how archaeologists and researchers find previously unrecorded sites across Ireland.

The enclosure was identified as a cropmark by Jean-Charles Caillère and Edward O'Riordan using Google Earth Pro imagery captured on 14 July 2018. Cropmarks form when buried features such as ditches, walls, or pits affect how plants grow directly above them; buried ditches tend to retain moisture and produce lusher, taller growth, while compacted surfaces or stone foundations stress the crop, creating paler patches. From the air, these differences in colour and height can trace the outline of structures that have long since vanished from the surface. The roughly circular shape is consistent with a ringfort or enclosure of early medieval date, a type of monument once numbering in the tens of thousands across Ireland and typically used as a farmstead with a surrounding earthen bank or ditch for protection, though without excavation no date or function can be confirmed here.
