Megalithic tomb, Gortyarrigan, Co. Donegal
On a gentle slope overlooking Lough Swilly, roughly 2 kilometres from its eastern shore, lie the scattered remains of what appears to be an ancient megalithic tomb.
Megalithic tomb, Gortyarrigan, Co. Donegal
The monument sits amongst fair pasture land in Gortyarrigan, County Donegal, though centuries of weather and human activity have left it in a severely ruined state. A stone field wall now runs through the site along its northwest edge, with a field drain running parallel on the southeast side, both cutting through what was once likely a complete structure.
The most prominent surviving features are two standing stones, or orthostats, that remain upright despite the passage of millennia. The larger of these, probably a sidestone of the original tomb, stands against the northwest face of the field wall at 0.8 metres high at one end, tapering down to half that height at the other. At right angles to this, and actually incorporated into the field wall itself, stands what may have been a jamb stone, measuring about a metre in height. Several other substantial stones lie scattered about the site; some appear to have toppled southeastward from their original positions, including a pillar-like stone that would stand at least 1.7 metres tall if re-erected, and a massive prostrate slab measuring 2.4 metres by 1.5 metres.
Whilst archaeologists believe these remains represent a megalithic tomb, the structure is too damaged and incomplete to determine its exact type or original configuration. The site was documented in detail during the Survey of the Megalithic Tombs of Ireland, compiled by Eamon Cody in 2002, and remains an intriguing, if fragmentary, reminder of Donegal’s prehistoric past. Despite its ruined state, the monument offers visitors a tangible connection to the ancient peoples who once chose this spot, with its commanding views across Lough Swilly, as a place to honour their dead.
