The first and second editions of the Ordnance Survey 6-inch maps, created during the 19th century, clearly marked a ‘Standing Stone’ at this location. By the time the third edition was published, however, the notation had changed to ‘Standing Stone (site of)’, suggesting the stone had already disappeared or fallen by that point.

The stone itself was modest in size, measuring approximately 4 to 5 feet in length according to local records. It once stood on marshy ground covered with gorse, a landscape typical of many parts of rural Donegal where prehistoric monuments blend into the wild countryside. Like many standing stones across Ireland, its original purpose remains a mystery; these ancient markers might have served as territorial boundaries, ceremonial sites, or astronomical markers for Bronze Age communities.

This information comes from the comprehensive Archaeological Survey of County Donegal, compiled in 1983 by Brian Lacey and his team of researchers. The survey documented field antiquities throughout the county, spanning from the Mesolithic period through to the 17th century, preserving details of monuments that might otherwise be forgotten. Though the standing stone at Baile Na Creige Thoir no longer exists, its recorded presence adds another piece to the complex archaeological puzzle of prehistoric Donegal.
