Tucked into scrub on a steep east-facing slope just west of the Kilshanny-Smithstown Road on the northern edge of Kilshanny village in County Clare, this spring has been named on Ordnance Survey maps since at least 1840, which means cartographers took it seriously even when the people nearby had largely stopped visiting it.

The name Toberinneenboy encodes a dedication to Inghean-Bhaoith, described in nineteenth-century sources as the patroness of Kilnaboy, a parish whose ruined church lies a short distance to the south. Holy wells in Ireland were typically associated with a saint or early Christian figure, and the annual pattern of visiting, praying, and performing rounds around the well was a form of folk devotion that survived the Reformation in many places. By the 1830s, however, this one was already described as seldom frequented, though its water retained a reputation for curing sore eyes, a common folk attribution for holy wells across the island. When E. Lenihan researched the holy wells of Kilshanny parish in the 1990s, he found that the name Iníne Baoith meant nothing to local people, and no trace of active devotion remained. The well was still called the blessed well, but its practical function had shifted: it was used to water cattle in dry weather.

The spring itself emerges from the base of a rocky outcrop, gushing into a small pool roughly half a metre across before being directed through a pipe into a stone trough and a concrete trough nearby. That combination of natural rock, a modest pool, and improvised agricultural infrastructure is quietly characteristic of how these sites persist, no longer venerated, not quite abandoned either.
