It stands just under a metre tall, subrectangular in plan, with its long axis oriented northwest to southeast, a modest but deliberate presence in the ground.

Standing stones of this kind are scattered across Ireland in considerable numbers, yet individually they remain among the least understood monuments in the archaeological record. They may mark boundaries, graves, astronomical alignments, or routes across terrain; in most cases, no single explanation fits all examples. This particular stone, sitting in rough grazing at Cnoc An Iúir, a placename that translates broadly from Irish as the hill of the yew, has left almost no documentary trace beyond its recorded dimensions and orientation. Its compact proportions, roughly 35 by 33 centimetres at the base, suggest a stone that was always relatively slight, raised without the ambition of the great megalithic monuments but placed with apparent intention nonetheless.
