That plain fact is about as far as the documented record currently goes, and there is something quietly telling about that gap. Holy wells are among the most numerous and least formally studied monuments in Ireland, numbering in the thousands, and many exist in a kind of administrative limbo, acknowledged on maps and in monument registers but not yet accompanied by any detailed description.

Holy wells occupy a peculiar place in Irish religious and social history. They predate Christianity in their original use, typically associated with local deities or spirits of place, and were gradually absorbed into Christian practice from the early medieval period onward. Most acquired the name of a saint, and many became the focus of patterns, the local term for a ritual gathering held on a saint's feast day, involving prayer, circumambulation of the well, and sometimes offerings left at the site. The townland name An Chloich Mhór Theas translates roughly as "the south of the big stone", a placename that hints at a local landmark now perhaps forgotten or unremarked. Whether the well and whatever stone gave the townland its name were ever connected in local tradition is not something the available record can settle.

Without further detail about this particular site, what can be said is that holy wells in Connaught vary considerably in character. Some retain elaborate stonework, carved crosses, or clusters of votive offerings; others are little more than a seeping hollow in a field, identifiable only to those who already know where to look.
