Less celebrated, though no less quietly present in the landscape, is the holy well that sits somewhere within this same townland. Holy wells, which are freshwater springs or seeps regarded as sacred, often pre-Christian in origin but later absorbed into Catholic devotional practice, are scattered across Ireland in their thousands, each carrying its own particular tradition of pattern days, votive offerings, and reputed cures. That one should exist at Gleninsheen is entirely in keeping with how the Irish landscape works; sites of natural significance tend to accumulate meaning across centuries and across faiths.

The Burren is unusually dense with archaeological and religious remains, its thin soils and exposed limestone pavement having preserved features that elsewhere were ploughed away or built over. The valley of Gleninsheen itself sits within a wider zone of Neolithic tombs, cashels, and field systems that speak to continuous human presence across several millennia. Holy wells in such environments often mark points where water emerges through the karst, the fractured and porous limestone that defines the Burren's character, and the emergence of fresh water from apparently dry rock would have seemed remarkable long before anyone thought to give it a saint's name. Unfortunately, the specific dedication, condition, and precise location of this particular well are not documented in any currently available source, and the details that would give it a fuller story remain unrecorded in the public domain.
