Bullaun stones, found across Ireland at early ecclesiastical and other ceremonial sites, are rocks bearing one or more cup-shaped depressions formed by sustained grinding or pounding; their exact purpose remains debated, though they are often associated with early Christian activity and folk custom. What makes this particular example quietly arresting is the pairing of two deep basins alongside a third, much shallower one, and the fact that the eastern bowl has been broken open at the top, leaving its rim incomplete.

The stone is earthfast, meaning it sits as a natural outcrop rather than a portable boulder, and is composed of sandstone with quartz pebble inclusions. Its dimensions are modest but precise: 0.93 metres north to south, 1.36 metres east to west, and rising no more than 0.13 metres above the ground surface. The two principal depressions are nearly matched in width, roughly 32 to 35 centimetres across, though the eastern one is noticeably deeper at 35 centimetres compared with 28 centimetres for the western. The stone is enclosed by a rubble stone wall identified as a cell or clochan, the latter being a type of dry-stone structure associated with early monastic settlement. A second bullaun stone, this one bearing a single depression, lies approximately 17.5 metres to the south-west, suggesting the site formed part of a larger complex of early activity rather than a single isolated feature.
