Rising 2.15 metres from the ground, this ancient monolith tapers from a base measuring 65 centimetres along its northeast to southwest axis, with a thickness of 45 centimetres. The stone's positioning on flat, well-maintained pasture makes it an accessible reminder of Ireland's prehistoric past, when such monuments served purposes we can only speculate about today.

Standing stones like this one are amongst Ireland's most enigmatic archaeological features, dating primarily from the Bronze Age period between 2500 and 500 BCE. Whilst their exact purpose remains debated amongst archaeologists, theories range from territorial markers and astronomical alignments to commemorative monuments or ritual sites. The orientation of this particular stone, aligned northeast to southwest, might have held significance for the people who erected it, possibly relating to seasonal solar events or serving as a waymarker along ancient routes through the Donegal countryside.

The stone's documentation in the Archaeological Survey of County Donegal places it within a broader context of the county's rich archaeological heritage, which spans from the Mesolithic period through to the 17th century. Its location near the Leannan river is particularly noteworthy, as prehistoric communities often situated important monuments near water sources, which held both practical and spiritual significance. Today, this weathered sentinel continues to spark curiosity amongst locals and visitors alike, standing as a tangible link to the beliefs and practices of Ireland's distant ancestors.
