It is modest by any measure, barely seven metres across internally, with walls only half a metre high and a metre wide, but its careful entrance, oriented to the east-south-east and nearly two metres wide, suggests this was a deliberate and considered construction rather than a casual field boundary.

The structure was recorded by archaeologists Quinn and Carroll in 2010, during an assessment carried out ahead of a proposed wind farm development at Doonens, Co. Cork. Their description notes walls of random construction, meaning the stones were laid without a regular coursing pattern, using both medium and large stones and slabs, some placed flat, others on their sides. This kind of rubble walling is common across Ireland in contexts ranging from early medieval enclosures to post-medieval agricultural buildings, and the circular form here raises the possibility that this was once a small dwelling or a stock enclosure, the two functions being difficult to distinguish without excavation. It sits just to the south of a trackway and north of another recorded field wall, suggesting it was once part of a broader pattern of land use now largely absorbed by the bog.
