That hollow, roughly forty centimetres across and six centimetres deep, is what makes it archaeologically significant. This is a bullaun stone, a type of ancient carved or worn basin stone found widely across Ireland, often in sacred or ecclesiastical settings. The purpose of such hollows has been debated for generations; suggestions range from the grinding of grain or pigments to ritual water collection, and in many parishes they are still associated with folk cures and patterns, the water gathered in the bowl believed to carry healing properties.

The stone itself is modest in size, less than a metre long and not quite a metre wide, with a thickness of only twenty centimetres. It lies flat rather than standing upright, which is common for bullauns, and its irregular shape suggests it was not heavily dressed or shaped to a particular form. The graveyard setting is telling. In Ireland, bullaun stones are frequently found beside early medieval church sites, and their presence in a burial ground often points to a long continuity of use at a single location, a place where people returned across many centuries for reasons that shifted between the practical, the spiritual, and the commemorative.
