It is a bullaun stone, a type of early medieval ritual or utilitarian object in which one or more bowl-shaped depressions have been worn or worked into the surface of a boulder. This particular example is unworked and irregular, meaning the stone itself was never shaped or dressed; only the hollow was formed, and even that sits off-centre, giving the whole object a slightly accidental quality that is somehow more arresting than a tidier specimen would be.

The stone measures roughly half a metre in both length and width, and its single bowl is modest in scale, approximately 32 centimetres long, 27 centimetres wide, and 17 centimetres deep. It was not always in its present location. Originally it stood within the old graveyard at Kilconnell village, a setting that would have been entirely typical for such objects. Bullaun stones are frequently found in ecclesiastical enclosures across Ireland, associated with early Christian sites and sometimes with patterns of local veneration that persisted long after the medieval period ended. The water that collects in the hollow was, and in some places still is, considered to have curative properties. The stone was subsequently moved to Glebe, separated from the graveyard context that gave it much of its original meaning.
