This absence from the cartographic record is not unusual for bullaun stones, boulders or outcrops into which one or more circular depressions have been deliberately ground, likely over many generations. Their purposes remain debated, though they are associated with early Christian and pre-Christian practice across Ireland, sometimes used for grinding, sometimes venerated as healing or cursing stones, and often linked to nearby ecclesiastical sites.

This particular example measures roughly a metre north to south and just over half a metre in height. What makes it especially interesting is that it carries two separate depressions rather than one. The southern basin is deep and well-formed, nearly circular, around forty centimetres across and seventeen centimetres deep, the kind of hollow that speaks to sustained and deliberate work. A few centimetres to the north sits a second depression, considerably shallower at only about three centimetres deep, but notably smooth to the touch. Whether the two were made at the same time, by the same hands, or for the same purpose is unknown. The stone was noted by the antiquarian Thomas Johnson Westropp in 1917, and was later photographed and documented in 2003. By the time of more recent survey, its upper surface had acquired a full cover of lichens, with mosses gathering around the lower edges and faint hairline fissures beginning to work into the stone.
