Holy wells occupy a peculiar corner of Irish sacred geography: natural springs or water sources that accumulated devotional significance over centuries, often associated with a patron saint whose feast day would draw local people for rounds of prayer, the tying of votive cloths to nearby trees, and the drinking or bathing in waters believed to carry curative properties. The designation "site of" signals that what once existed here may no longer be visible in any obvious form, the physical focus of that devotion either lost, overgrown, or altered beyond recognition.

The pattern is a familiar one across Ireland. Wells dedicated to local or regional saints were frequently absorbed into the Christian calendar while retaining older ritual practices that predate it, a layering of belief that made them both religiously orthodox and stubbornly folk in character. The name Toberelleen, with its affectionate diminutive, hints at a well of some intimacy and local particularity rather than a major pilgrimage site, the kind of place known within a community rather than celebrated across a county. Such wells were often marked by a surrounding enclosure, a stone surround, or a nearby tree hung with offerings, and their care was typically informal, maintained by local custom rather than any institutional authority. Whether the Ballyscully well ever had a named patron, or what specific traditions were attached to it, remains obscure without further documentation.
