Measuring roughly 33.5 centimetres long and not quite 17 centimetres tall, it has an oval basin hollowed into its upper face, the kind of shallow stone vessel used as a baptismal or holy water font. What makes it quietly arresting is the detail at one corner: a small carved stone head, heavily weathered now, worn to the point where expression and feature have almost dissolved back into the rock.

The font did not begin its life at Barranisky. It was originally located at Kilbride, a place name scattered across Ireland and typically associated with early Christian foundations dedicated to St. Brigid. How or when it made the journey to its current home in St. Patrick's church is not recorded, but when inspectors examined the piece in 1999, it was already installed in the east transept, having evidently been moved at some earlier point. The red sandstone itself is worth a moment's attention: the material is less common in ecclesiastical stonework than limestone or granite, and its warm colour makes the object stand out against the cooler tones of a typical church interior. The carved head on the corner, though now barely legible as a face, places the font within a broader tradition of figured stonework in Irish ecclesiastical contexts, where human or mask-like heads appear on fonts, corbels, and architectural details, sometimes interpreted as protective figures, sometimes as remnants of far older carving conventions absorbed into Christian use.
