This prehistoric monument stands roughly 1.75 metres tall and displays an interesting tapered form; its width narrows from about 69 centimetres at the southern end to just 48 centimetres at the northern face, whilst maintaining a thickness of around 60 centimetres throughout. The stone's almost square plan and north-south orientation suggest deliberate placement by its original builders, though its exact purpose remains a matter of speculation.

Standing stones like this one dot the Irish landscape and likely date from the Bronze Age, somewhere between 2500 and 500 BCE. They may have served various functions: territorial markers, commemorative monuments, or perhaps elements in astronomical observations. The Ballycharry stone's survival, even if now serving as part of a farmyard wall, speaks to both the durability of these ancient monuments and the pragmatic approach rural communities have historically taken to incorporating prehistoric features into their working landscapes.

The stone sits on relatively level ground, which was likely an important consideration for its original placement. Whilst many standing stones across Ireland have been moved, destroyed, or lost to development over the centuries, this example at Ballycharry continues to mark its spot, albeit in altered circumstances. Its documentation in the Archaeological Survey of County Donegal helps preserve knowledge of these monuments, even as their original contexts and meanings fade into prehistory.
