The one at Ballynacally, a small village on the Fergus Estuary in the west of the county, belongs to this quietly persistent tradition. Holy wells in Ireland were typically associated with a patron saint, visited on a specific feast day, and used for patterns, a word for the rounds of prayer and circumambulation performed at such sites. Some accumulated offerings: rags tied to nearby bushes, coins pressed into bark or stone, crutches left behind as evidence of cures. Others gradually fell out of active use, becoming simply a feature of the landscape, known locally but rarely remarked upon further afield.

Ballynacally itself sits within a landscape shaped by the tidal reach of the Fergus, a place where land and water have long been negotiated rather than fixed. The village name derives from the Irish Baile na Caillí, generally translated as the town of the old woman or the hag, a figure that in Irish tradition often carries associations with sovereignty, the land, and boundary places. Whether the well's history connects in any direct way to that naming is not something the surviving record makes clear, but the convergence is the kind of thing that makes a place feel layered even before you know its full story.

The well is recorded as a monument, which places it within the broader category of sites considered to have archaeological or historical significance, though the details of its specific dedications, patterns, or physical character are not presently documented in accessible sources. What can be said is that its survival as a named and recorded site, however quietly, suggests it held enough local meaning to be noted at all.
