Located at Leaght on a north-facing slope surrounded by fair grazing land, this prehistoric monument stands as a silent witness to thousands of years of human activity in the region. Its absence from the first edition OS 6-inch map suggests it may have been overlooked by early surveyors or simply not considered significant enough to record at the time.

Standing stones like this one are amongst Ireland's most enigmatic archaeological features, erected during the Bronze Age between 2500 and 500 BCE. While their exact purpose remains debated amongst archaeologists, they likely served multiple functions; as territorial markers, commemorative monuments, or perhaps as part of prehistoric astronomical observations. The Leaght stone's position on a slope facing north might have held particular significance for the people who erected it, though without excavation or further investigation, its specific role in the prehistoric landscape remains a mystery.

This monument was documented as part of the comprehensive Archaeological Survey of County Donegal, conducted by Brian Lacey and his team in 1983. The survey catalogued field antiquities spanning from the Mesolithic period through to the 17th century, creating an invaluable record of Donegal's archaeological heritage. Today, the standing stone at Leaght continues to occupy its hillside position, a tangible link to the prehistoric communities who once inhabited this corner of northwest Ireland.
