What makes it quietly peculiar is not its size, just 1.2 metres across and less than a metre deep, but the fact that within roughly eighty metres of it stands another well carrying the exact same name. Two wells, both called Patrick's Well, both on the same stretch of shoreline, as though the saint's presence needed to be recorded twice.

The well is associated with St Patrick through a story recorded by Korff and O'Connell in 1985: that he struck the ground with his staff and fresh water rose up. This is a common motif in Irish hagiography, where holy wells, springs believed to carry spiritual or healing properties and traditionally the focus of patterns, meaning local devotional gatherings, are linked to a founding act of miracle. This particular well has three sets of steps leading down to the water, one set built into the southern wall and opposing sets in the west and east walls, a practical arrangement that suggests the well was designed for access by several people at once, perhaps for the drawing of water or for ritual purposes. It is, according to local knowledge, still a focus of devotion.

The tidal character of Bridge Lough adds an unusual dimension to the setting. The lake opens eastward into Kinvarra Bay, meaning the surrounding landscape shifts between salt and fresh water at its margins, while the spring itself would have provided a reliable source of fresh water close to the shore. Whether the proximity of the two identically named wells reflects a doubling of tradition, a boundary marker, or simply a quirk of local naming is not recorded, but it is the kind of detail that rewards a slow look at the ground rather than a glance from a distance.
