It is modest to the point of near-invisibility, measuring just over a metre and a half east to west and barely more than half a metre north to south, accessible through a gap in the wall with a single step at the southeast. What distinguishes it is not its scale but what leans against its eastern side: a stone slab inscribed with the name Kirwan and the date 1706, left there for reasons that remain unexplained, a marker that quietly anchors the well to a specific moment in time without fully accounting for itself.

Holy wells in Ireland were typically local focal points for devotion, healing, and ritual, their significance often bound up with a saint or a particular community practice. This one carries a tradition of episcopal use: local knowledge holds that a bishop who lived near the well drew water from it to baptise children. No name is attached to this bishop in surviving accounts, and the Kirwan slab, bearing one of Connacht's prominent Catholic family names from the period, may or may not be connected to that same tradition. The 1706 date places the inscription in the early eighteenth century, a period when public Catholic practice in Ireland operated under considerable legal pressure, which gives an added dimension to the idea of baptisms being performed at a small, unassuming well in marshy ground rather than in any formal church setting.
