A holy well that may not be what its name suggests sits at the foot of a south-facing slope in Gorteen, County Waterford. Locally it is called Saint Gehan's Well, but the Ordnance Survey Name Books record an older possibility: Tobar Dé hAoine, meaning Friday's Well. The two names point to different kinds of devotion, one to a named saint, the other to a day of the week with its own penitential weight in Irish Catholic practice, and the discrepancy has never been fully resolved. The well itself is a modest structure, circular, just 1.3 metres in diameter, shaped by drystone walling and capped with a lintel. On top of that lintel sit a few loose stones, the last surviving fragments of a penitential cairn. An iron ringed-cross stands nearby. The whole arrangement lies at the western edge of a subcircular pond, roughly 15 metres north to south and 10 metres east to west, which gives the site an unexpectedly calm, almost enclosed quality.

Like many Irish holy wells, this one carried a cluster of associated practices. The water is reputed to cure eye ailments, a belief attached to numerous wells across Ireland and often linked to the visual clarity of the spring itself. There was also a rag-tree, the kind of thorned or otherwise notable tree to which visitors would tie strips of cloth as votive offerings, the decay of the cloth thought to carry away illness or hardship. That tree has since been removed without trace. The pattern, which is the local term for the ritual gathering and circuit of prayers held at a holy well on its appointed feast day, was observed here each year until 1919, when it lapsed entirely. It was then resumed around 1980, and is now held on or around the 19th of July. The gap of some sixty years is itself quietly telling, a well falling silent within living memory and then finding its way back into use again.
