Most bullaun stones, which are boulders or slabs bearing one or more rounded, cup-like hollows worn or carved into their surface, lie flat, their depressions used for grinding, ritual water-holding, or purposes now lost to us. This one is different. It stands nearly a metre across and around thirty centimetres thick, and the depression on its exposed face is not the usual worn bowl but something more precise: circular, with vertical sides and a flat base, roughly seventeen centimetres across and only eight millimetres deep. Whether it was made that way, or arrived at that form through centuries of use, is not clear.

The stone sits on the eastern side of an enclosure within the burial ground, partly embedded in the earth, so its full dimensions remain uncertain. That combination, an upright orientation, an atypical depression, a cemetery setting, marks it out as something that does not fit neatly into any single category. The function is genuinely unresolved. What local tradition has supplied instead is a practical reputation: the stone is said to have curative powers, and is considered particularly effective for ailments of the head, including headaches. This kind of association is not unusual for bullaun stones across Ireland, where the water collected in their hollows has long been credited with healing properties, but the specificity here, the head, and the form of the hollow itself, which sits off-centre on the face of an upright slab, gives the tradition a slightly different character from the more familiar recumbent examples.
