The hollow is modest, roughly 24 by 23 centimetres across and 12 centimetres deep, but its regularity is unmistakable. This is a bullaun, a term for these deliberately hollowed depressions found in boulders and rock outcrops across Ireland. Their purpose remains genuinely uncertain; some are associated with early Christian sites and are thought to have held water used in ritual or curative contexts, while others appear far older, possibly connected to grain grinding or other practical uses. What they share is a quiet persistence, carved or worn into stone that was never going anywhere.

The boulder itself is earthfast, meaning it is fixed in the ground rather than a loose surface find, and extends outward from the slope at its north-west end. It measures roughly three metres along its longer axis and rises to about ninety centimetres above the surrounding ground. Granite is not the easiest material to work, which makes the clean, bowl-shaped depression at its upper surface all the more deliberate in appearance. No historical record attached to this particular stone names who made it or when, and without associated finds or excavation that question stays open. The wooded setting and sloping ground mean it sits largely unannounced in the landscape, the kind of thing a person could walk past without registering what they were seeing.
