According to residents, the stone, which stood approximately one metre tall, was removed from its ancient position in 1979. The monument had occupied a spot on level ground along a ridge that runs from northeast to southwest, a location that would have made it visible for considerable distances across the surrounding countryside.

The original documentation of this lost monument comes from the Archaeological Survey of County Donegal, a comprehensive catalogue compiled by Brian Lacey and his team of archaeologists in 1983. This survey attempted to record every field antiquity in the county, from prehistoric Mesolithic sites through to structures from the 17th century. The standing stone at Sesnacully represents just one of many ancient markers that have vanished from the Irish landscape in recent decades, whether through agricultural improvements, development, or simple neglect.

While the physical stone may be gone, its inclusion in the archaeological record ensures that future generations will know of its existence. Standing stones like this one typically date from the Bronze Age, roughly 2500 to 500 BCE, and served various purposes; they might have marked boundaries, acted as memorial stones, or held ritual significance for the communities that erected them. The loss of such monuments removes tangible links to Ireland’s deep past, making the work of recording and preserving what remains all the more crucial.
