A concentric enclosure, roughly 160 metres in diameter, lies quietly in the landscape, its outlines invisible to anyone standing at ground level but legible from above as a series of curved earthwork rings, one set within another.

The site came to light in 2013, not through excavation or fieldwork, but through a desk-based review of LiDAR data. LiDAR, which stands for Light Detection and Ranging, works by firing pulses of laser light from an aircraft and measuring how long they take to bounce back, producing an extraordinarily precise three-dimensional map of the ground surface beneath vegetation and soil disturbance. It has become one of the more transformative tools in Irish landscape archaeology, revealing enclosures, field systems, and other earthworks that centuries of agriculture have reduced to near-nothing at eye level. The Doony site emerged from exactly this kind of review, identified as a possible concentric enclosure on the basis of what the LiDAR returns suggested about the underlying topography. Concentric enclosures, in the Irish context, typically consist of two or more roughly circular banks or ditches arranged around a central area, and are associated with a range of periods and functions, from prehistoric settlement to early medieval use, though without excavation it is rarely possible to say more than that. At around 160 metres across, this is a substantial example if the identification holds.
