Located in Fortstewart, this ancient marker sits on what is now good pasture land, its weathered surface offering few clues to its original purpose or the people who erected it thousands of years ago.

The stone’s absence from Ordnance Survey 6-inch maps adds an air of mystery to its presence, suggesting it may have been overlooked by Victorian cartographers or perhaps considered too unremarkable to warrant inclusion. Yet its survival through millennia speaks to its significance in the landscape, whether as a territorial marker, a memorial, or part of a larger ceremonial complex now lost to time. Standing stones like this one are found throughout Ireland, silent sentinels that once served purposes we can only speculate about today.

This particular monument was documented as part of the comprehensive Archaeological Survey of County Donegal, compiled in 1983 by Brian Lacey and his team of archaeologists. The survey catalogued field antiquities spanning from the Mesolithic period right through to the 17th century, preserving vital information about sites that might otherwise be forgotten. For visitors seeking out this ancient stone today, its position near Lough Swilly offers not just a glimpse into prehistory but also sweeping views across one of Donegal’s most scenic waterways.
