This ancient monolith stands approximately two metres tall, its weathered surface tapering from a broad base of half a metre to a narrow point just 15 centimetres wide at its peak. The stone's placement appears deliberate; whoever erected it chose this spot carefully, ensuring clear sightlines along the Finn Valley that stretches out below.

Standing stones like this one dot the Irish landscape, their original purpose lost to time but likely connected to ritual, territorial marking, or astronomical observation. The Demesne stone's commanding position suggests it may have served as a landmark or meeting point for the communities who inhabited this region thousands of years ago. Its survival through millennia speaks to both the durability of the local stone and the respect successive generations have shown for these enigmatic monuments.

The site was formally documented in the Archaeological Survey of County Donegal in 1983, though locals would have known of its presence for generations. Today, it remains accessible to visitors who wish to contemplate this tangible link to Donegal's ancient inhabitants, standing much as it has since the Bronze Age, weathered but unbroken against the backdrop of the Finn Valley.
