What makes it worth attention is the hollow carved or worn into its upper surface: a single deep circular basin, 35 centimetres across, positioned at the centre of a stone that measures less than 60 centimetres on each side. The basin takes up a substantial portion of the stone's face, which gives it an almost purposeful, concentrated quality.

This is a bullaun stone, a type of ancient carved rock found at early Christian and pre-Christian sites across Ireland. The word comes from the Irish "bullán", meaning a round hollow or bowl, and these stones are generally thought to have served ritual or practical purposes, possibly connected with grinding, healing, or the collection of rainwater believed to have curative properties. Their precise origins and uses are still debated, but they are frequently found near ecclesiastical sites, holy wells, and burial grounds. The proximity of this example to a children's burial ground, known in Irish as a "cillín", a type of unconsecrated ground historically used to inter unbaptised infants and others excluded from formal church burial, places it within a landscape layer that was clearly regarded as set apart from ordinary use for a very long time.
