Holy wells are among the most enduring features of the Irish countryside, typically springs or natural water sources that acquired sacred associations, often pre-Christian in origin but absorbed into Catholic devotional practice over centuries. They were places of pattern days, pilgrimage, and the tying of votive rags to nearby trees or bushes. The well at Erribul belongs to this long tradition, though the particulars of its history, its patron saint if it had one, its local customs, and its physical character, remain formally undocumented in any accessible public record.

Clare is county particularly dense with such sites. The western seaboard counties retained strong popular devotional traditions around holy wells well into the modern period, with communities gathering on feast days associated with local saints to walk the rounds, a ritual circuit of prayer performed a set number of times in a set direction around the well or its enclosure. Whether Erribul's well supported such practices, and for how long, is not currently known from available sources. The townland name itself, Erribul, likely derives from Irish and reflects the deep layering of place-names across this part of Munster, though the precise etymology is not recorded here.
