The one at Annagh, in County Clare, is among the more quietly obscure examples: recorded as a monument, mapped, given a classification, and yet largely undocumented in any publicly accessible form. That gap in the record is itself revealing. Thousands of holy wells survive across Ireland, many of them still visited on pattern days, the local feast days tied to a patron saint, when people walk a prescribed route, say prayers, and sometimes leave votive offerings such as rags, rosary beads, or coins pressed into the bark of a nearby tree.

Clare has an exceptional concentration of such sites, reflecting both the county's deep pre-Christian ritual landscape and the way early medieval Irish Christianity absorbed and reframed those older practices. Wells were associated with healing, with particular ailments assigned to particular saints, and with the power of water as a threshold between worlds. Annagh, a townland name derived from the Irish eanaigh, meaning a marsh or watery place, suggests a low-lying, possibly seasonally flooded setting, which would be entirely consistent with the kind of liminal, water-edged ground where such sites typically appear. Beyond the name and the classification, the specific history of this well, its patron saint if it has one, any pattern day traditions, and the current condition of the site, remain unrecorded in any available public source.
