This ancient monolith stands 1.5 metres tall, with a narrow profile measuring just 25 centimetres wide and 20 centimetres thick, oriented along a north-south axis. Small stones have been carefully packed around its base, perhaps placed there centuries ago to help secure this prehistoric monument against the coastal winds.

The stone's modest dimensions belie its significance as part of Donegal's rich archaeological landscape. Standing stones like this one dot the Irish countryside, silent witnesses to prehistoric communities who erected them for reasons that remain partly mysterious. Some may have marked boundaries or burial sites; others possibly served astronomical purposes, tracking the movements of sun and moon across the seasons. Their exact purpose often depends on their specific location and any associated features nearby.

This particular example was documented in the comprehensive Archaeological Survey of County Donegal, compiled 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 the county's archaeological heritage. The stone's prominent position on elevated ground overlooking Abbey Bay suggests it may have served as a territorial marker or navigational aid, visible to both land travellers and those approaching from the sea.
