At Raheennamadra in County Limerick, a well bearing the name of St. Patrick sits on the northern verge of a public road at the townland boundary between Raheennamadra and Mitchelstowndown East, a liminal position that is, in its own way, entirely appropriate for a site whose religious identity appears to have been borrowed rather than inherited.

The well is annotated as St. Patrick's Well on the Cassini edition of the Ordnance Survey Ireland six-inch map, placing its formal documentation somewhere in the nineteenth century, when those surveys were undertaken. It lies within the parish and barony of Knocklong, in south County Limerick. What makes the site particularly interesting is a piece of folklore preserved in the Schools' Collection, a vast archive of local knowledge gathered by Irish schoolchildren in the late 1930s. A pupil from Glenbrohane School recorded the telling observation that there appeared to be no patron saint associated with this locality, and yet the Catholic church nearby was called St. Patrick's, and there was a well not far from it also carrying his name. The implication is that the Patrick connection was a label applied to an existing sacred site rather than one rooted in any local tradition of pilgrimage or miracle attributed to the saint himself. Holy wells, which are freshwater springs regarded as sacred and often associated with healing or prayer, were frequently rededicated to Christian saints over centuries, absorbing older patterns of veneration into a new religious framework.

The well sits along the road marking the boundary between the two townlands, which means it can be approached from the public way without crossing private land, though the exact condition of the site at any given time is worth checking in advance. The Cassini map annotation remains the clearest guide to its location, and cross-referencing that with the modern OSi mapping layers online will help narrow it down. The Schools' Collection entry is freely accessible through the Dúchas archive at duchas.ie, and reading it before visiting adds a layer of context that the site itself, modest and easily passed, does not announce.
