Here, atop a modest rock outcrop measuring just over a metre long and slightly less than a metre wide, you’ll find a curious circular depression carved into the stone’s surface.

This water-filled hollow, measuring 23 centimetres across and 15 centimetres deep, is what’s known as a bullaun stone. These mysterious basins, found throughout Ireland, were likely created during the early Christian period, though their exact purpose remains a subject of debate amongst historians and archaeologists. Some suggest they were used for grinding grain or herbs, whilst others believe they held holy water for blessing rituals; the worn, smooth surfaces hint at centuries of use by local communities.

The bullaun at Cill Ghabhlaigh (anglicised as Kilgole) is particularly accessible for those interested in Ireland’s ritual landscape, positioned right alongside the road where travellers have passed for generations. Like many bullaun stones across the country, rainwater naturally collects in its basin, and local tradition often attributes healing properties to these waters, especially for ailments like warts or toothaches. Whether you believe in such remedies or not, there’s something undeniably atmospheric about encountering these ancient stones in their original settings, unchanged except for the gentle weathering of countless Irish seasons.
