A well named for a saint, mapped twice across nearly a century of Ordnance Survey editions, and yet carrying no trace of the devotional life that usually surrounds such places. Holy wells in Ireland were typically focal points for patterns, those communal gatherings of prayer and ritual tied to a saint's feast day, and the physical site would often accumulate offerings, rags tied to nearby branches, or stonework framing the water. At Knocknahoola, on a high plateau in County Waterford with a slight southward slope, none of that evidence exists. No record of pilgrimage, no folklore of cures, no local tradition of veneration has been found to explain why the name St. Michael's Well attached itself here at all.

The well appears on the Ordnance Survey six-inch map of 1840 and again on the 1927 edition, named consistently on both, which suggests the designation was already established before the first surveyors arrived and was not simply a cartographic invention. Whether the name reflects a genuinely forgotten cult, a casual local usage that was never backed by organised religious practice, or simply a misattribution that hardened into convention through repetition on printed maps, is impossible to say. What is clear is that the well no longer survives; it was lost to a coniferous forest plantation, a fate that claimed many field monuments across Ireland during the large-scale afforestation programmes of the twentieth century.
