This one at Dooneens, in County Cork, qualifies on neither count. What survives is barely there at all: two short perpendicular walls meeting at a right angle, only a single course of stone remaining, the whole structure overgrown with grass and moss and sitting no higher than ten centimetres above the surrounding ground. It is, in the most literal sense, a boundary that has almost ceased to exist.

The remains were documented by Quinn and Carroll in 2010, as part of an archaeological and cultural heritage assessment carried out ahead of a proposed wind farm at Dooneens. Their description is clinical and precise: random construction, meaning the stones were laid without any regular coursing or dressed faces, which was the common approach for agricultural field walls built without specialist labour. The two walls together run to a total length of thirty-three metres, and at seventy centimetres wide the structure would once have been a modest but functional division of pasture. It sits in relatively flat ground to the north-east of another recorded wall in the same area. Beyond that, the historical context is thin. No date of construction is recorded, no owner, no particular agricultural event that might explain why this corner of Cork was being divided in this way.
