A massive stone slab, measuring roughly 2.5 metres by 2 metres and 1.5 metres thick, rests horizontally across three naturally outcropping rocks. The builders of this feature took care to ensure its stability, placing two pad stones between the slab’s base and one of the supporting outcrops, creating a deliberate and carefully engineered arrangement.

The structure extends beyond just the impressive raised slab. Low stones set on edge in the surrounding bog mark out a rectangular space measuring 4.5 metres by 1.5 metres, with the raised slab forming one side of this enclosure. Whilst the arrangement might initially suggest a megalithic tomb, archaeological surveys have ruled this out; the feature doesn’t match the typical characteristics of prehistoric burial monuments found elsewhere in Ireland.

The true purpose and age of this monument remain unknown, adding to the mystery of Donegal’s archaeological landscape. First formally recorded by Verling in 1990 and later included in the official Record of Monuments and Places in 1995, the structure was subsequently documented in the comprehensive Survey of the Megalithic Tombs of Ireland, compiled by Eamon Cody in 2002. Whether it served as a territorial marker, had ritual significance, or fulfilled some practical purpose for the communities who built it, this enigmatic stone arrangement continues to stand as a testament to human ingenuity in shaping the landscape.
