This standing stone in Cuillagh sits on top of a small hill in pasture, planted about a metre to the south of a field bank that runs roughly northwest to southeast. What sets it apart, modestly but genuinely, is its material: it is a conglomerate stone, meaning it is composed of older rock fragments cemented together over geological time into a single mass, giving it a rough, composite texture quite distinct from the smooth-faced slabs more commonly associated with prehistoric monuments.

The stone measures roughly 25 centimetres by 20 centimetres in cross-section and stands 1.45 metres tall, a modest but deliberate presence on its hilltop. Whoever erected it left no obvious clue as to why it faces the direction it does, since surveyors have noted no perceptible orientation, no alignment towards a cardinal point, a solstice sunrise, or any other feature in the surrounding landscape. Standing stones of this kind are broadly prehistoric in origin, though pinning them to a specific period is rarely straightforward without excavation. They have been interpreted variously as boundary markers, ritual focal points, and grave indicators, and the honest answer is that most remain unexplained. This one, catalogued in the Archaeological Inventory of County Leitrim compiled by Michael J. Moore and published in 2003, sits quietly in that same unresolved category.
