Known locally as Leachtas, this enigmatic structure consists of what appears to be half of a circular earthwork, roughly 10 metres across. The surviving portion forms a crescent-shaped bank of earth and stone, whilst the northwestern half has been lost, seemingly destroyed when the adjacent NE-SW road was constructed with its modern earthen embankment cutting straight through where the rest of the monument would have stood.

The site occupies a rather dramatic position on rough pasture that falls away sharply to the southeast towards a stream below. Originally, rock outcrops would have loomed over the monument from the northwest, though these have since been heavily quarried. Today, the interior of this ancient earthwork serves a rather undignified purpose as a gravel dump, obscuring whatever original features might have existed within the enclosure.

The true nature and purpose of this monument remains unclear; it’s simply classified as an unidentified cairn in archaeological records. Whether it served as a burial site, a ritual enclosure, or had some other function in the landscape is now impossible to determine without excavation. Its survival, even in this truncated form, offers a tantalising glimpse of the prehistoric landscape of Donegal, where such monuments once dotted the hillsides, marking territories, burial grounds, or sacred spaces for communities long vanished.
