This small island appears to be an artificial stone cairn, carefully constructed around natural rock formations that were already present in the lough. What makes this site particularly fascinating is the evidence suggesting that ancient inhabitants built a causeway connecting the northern corner of the island to the mainland, though centuries of peat growth and water erosion have obscured much of this prehistoric pathway.

The island is believed to be a crannog, a type of artificial island dwelling that was common throughout Ireland from the Bronze Age through to the medieval period. These structures were typically built by laying down layers of stone, timber, and peat in shallow water, creating defensible homesteads for families of high social standing. The remote location of this particular crannog, surrounded by desolate moorland, would have offered its inhabitants both protection from raiders and control over local resources.

Archaeological surveys conducted in the early 1980s documented the site as part of Donegal’s rich tapestry of field antiquities, which span from the Mesolithic period to the 17th century. Today, the crannog stands as a silent testament to the ingenuity of Ireland’s ancient peoples, who transformed this inhospitable landscape into a secure dwelling place. While the boggy terrain makes access challenging, the site remains an evocative reminder of how our ancestors adapted to and shaped even the most unforgiving environments.
