A bullaun is a large stone, usually a boulder, with one or more cup-shaped depressions ground into its surface. The hollows were almost certainly made by human hands, though precisely when, and to what end, remains genuinely uncertain. Some are associated with early Christian sites, others appear far older, and the water that collects in them has long been credited with curative properties in Irish folk tradition. This one, in its Mayo townland, belongs to a category of monument that is common enough across Ireland to be well-recognised, yet rare enough in any given parish to be worth noting.
