Measuring approximately one metre in height and 1.75 metres in width, this prehistoric monument is oriented northwest to southeast, following a pattern common to many such stones across Ireland. The stone at Carrowreagh Or Craignacally stands as a silent witness to thousands of years of human activity in this coastal landscape.

Standing stones like this one are amongst Ireland's most enigmatic archaeological features, with their original purpose still debated by scholars. They may have served as territorial markers, commemorative monuments, or held ritual significance for the communities that erected them during the Bronze Age, roughly 4,000 years ago. The positioning of this particular stone, with its commanding view over the surrounding farmland and proximity to the shore, suggests it held importance for the ancient inhabitants of Doagh Isle.

Today, the stone continues to mark the landscape much as it has for millennia, though the world around it has transformed from wilderness to cultivated fields. Its documentation in the Archaeological Survey of County Donegal ensures that this modest yet significant monument remains part of the county's recorded heritage, connecting modern visitors to the island's deep prehistoric past.
