A bullaun is a large rock, usually boulder-sized, into which one or more rounded depressions have been deliberately ground. The hollows collect rainwater, and for centuries, possibly much longer, such stones have been associated with healing, cursing, and the kind of localised devotion that predates and then quietly absorbed Christianity. They appear near early churches, holy wells, and ancient boundaries, often without any written record of how they came to be where they are or what specific rituals attached themselves to them.

Pollrone itself is a townland in the south of County Kilkenny, in a part of the county where early medieval ecclesiastical remains are not unusual. Bullaun stones in this region tend to cluster near the sites of early monastic foundations or parish churches with deep roots, though whether the Pollrone stone has any direct association with a particular site or dedication is not currently documented in the available record. What can be said generally is that these stones were rarely moved far from their original settings, which means the stone at Pollrone is likely where it has always been, embedded in the landscape it belongs to rather than displayed or relocated.
