Somewhere on a south-facing slope in County Waterford, a holy well once drew crowds every fifteenth of August, yet today there is nothing left to see. The well itself has vanished, and the name that belonged to it has quietly migrated roughly 530 metres to the east, attaching itself to a different natural spring entirely. It is the kind of displacement that happens when a place loses its ritual purpose, and its memory slowly loosens from the ground.

The site belongs to an early ecclesiastical enclosure known as Cíll Eoghan, meaning the church of Eoghan, a place-name recorded and interpreted by Patrick Power in his study of the place-names of the Decies, published in its second edition by Cork University Press in 1952. The well, recorded on Ordnance Survey six-inch maps of both 1840 and 1928 as Tobar Eóin, sat just outside the boundary of this enclosure to the south-west. A pattern, which is the Irish tradition of visiting a holy well on a saint's feast day to pray, walk circuits, and sometimes perform prescribed rituals, was held here annually on the fifteenth of August. That date corresponds with the feast of the Assumption, though the well's name links it to the early saint Eoghan rather than to Marian devotion. The pattern was suppressed in 1825, part of a broader effort by Catholic clergy during that period to curtail popular religious gatherings at wells and other outdoor sites, which were sometimes considered disorderly or theologically irregular. After suppression, the well appears to have fallen out of use entirely, and the physical structure is no longer evident on the ground.
