This is a bullaun stone, a type of ancient stone feature found across Ireland, typically characterised by one or more cup-shaped depressions ground into the rock. Their purpose remains debated; some are associated with early Christian sites and the collecting of rainwater thought to have curative properties, while others appear to predate Christianity entirely and may have served as grinding or pounding surfaces.

The stone itself is subrectangular in shape, roughly 62 centimetres by 56 centimetres, and relatively low-lying at just 14 centimetres in height. The circular hollow sits off-centre on the flat upper surface, measuring around 18 centimetres across and 6 centimetres deep, dimensions that suggest repeated, purposeful use over a considerable period. Its position on the riverbank beside Faha House places it within a landscape that would have been inhabited and worked for centuries, though no specific historical record of its use or the circumstances of its discovery accompanies the physical description.
