It is wide enough to pass a person through, and according to local tradition, that is precisely what it was for: anyone who was sick and crawled or squeezed through the perforation would be cured. The stone, marked on the 1940 Ordnance Survey six-inch map simply as "Holed Stone", belongs to a category of monuments found scattered across Ireland and Britain in which a deliberate opening in a standing stone carried ritual or healing significance.

The slab itself is substantial, measuring 2.15 metres high, 2.65 metres wide, and only 0.2 metres thick, an unusually broad and thin form that gives it something of the quality of a great flat screen rather than a pillar. Its long axis runs east to west. The western edge is vertical and grades smoothly into a gently arching top, while the eastern side is interrupted by a pronounced step or indentation, as though a section was once broken away or was always shaped that way. The perforation runs 0.86 metres through the broad face of the stone, set off-centre toward the east. Holed stones of this kind appear across the prehistoric landscape of Ireland and are sometimes associated with oath-taking, healing, or the formalising of agreements, the idea being that passing through, or joining hands through, the opening bound a person to something larger than themselves, whether a promise, a community, or a hoped-for recovery.

The stone sits in damp pasture, a setting that feels appropriately marginal, placed at the meeting point of field drains and townland edges, the kind of threshold geography that often attracted monuments intended to mark or mediate transitions of one sort or another.
