Initially recorded in the Sites and Monuments Record for County Donegal in 1987 as a possible megalithic tomb, this small structure tells a different story upon closer inspection. The feature consists of a shallow, circular depression measuring less than two metres across and roughly 30 centimetres deep, with small upright stones lining the southern half of its perimeter; some of these stones have come loose over time.

Despite its initial classification, experts have firmly concluded that this is not a megalithic tomb at all. The artificial nature of the depression is clear, but its true purpose remains a mystery. It lacks the characteristic features typically associated with prehistoric burial sites in Ireland, such as capstones, passages, or chambers. The arrangement of stones is too modest and irregular to fit the pattern of known megalithic monuments from the Neolithic or Bronze Age periods that dot the Irish landscape.

This enigmatic feature was formally documented in the Survey of the Megalithic Tombs of Ireland, Volume VI, compiled by Eamon Cody in 2002, where it was definitively ruled out as a tomb. While it may not be the grand prehistoric monument it was once thought to be, this anomalous stone group continues to intrigue visitors and researchers alike, serving as a reminder that not every ancient structure fits neatly into archaeological categories, and that Ireland's landscape still holds mysteries waiting to be solved.
