This well in Cartown, County Limerick, sits in ordinary pastureland on the western bank of a stream, and there is nothing visible at ground level to suggest it was ever there at all. No stonework, no votive offerings, no worn path. Only a map entry, and then its absence.

The well's early history is recoverable only through cartography. It was annotated as St. Bridget's Well on the first edition Ordnance Survey six-inch map, the large-scale survey carried out across Ireland in the nineteenth century that recorded vernacular and religious place-names with unusual thoroughness. Bridget, the fifth-century abbess of Kildare whose feast day falls on the first of February, was one of the most widely venerated saints in Ireland, and wells dedicated to her are found across every province. On later editions of the OS maps, however, this particular well disappears entirely, suggesting it had already fallen out of use or recognition by the time surveyors returned. What makes the situation in Cartown especially curious is that a second holy well, also dedicated to St. Bridget and carrying its own separate record number, lies just 360 metres to the south in the same townland. The notes were compiled by archaeologist Caimin O'Brien and uploaded in July 2019.

For anyone inclined to look, the location is pasture rather than publicly managed land, so access would depend on landowner permission. The stream bank on the western side is the only navigational reference available, and with no surface remains visible there is genuinely nothing to see once you arrive. The value here is less in the visit itself and more in what the record suggests: a landscape in which two separate St. Bridget's wells existed within a few hundred metres of one another, one of which has been quietly erased from the official record while retaining a faint trace in nineteenth-century surveying.
