This one at Cloncagh, in County Limerick, has left almost no trace at all. The well sits in ordinary pasture on ground that slopes gently southward, and by the time folklorist Caoimhín Ó Danachair came to document it in 1955, even local memory had grown thin. He recorded only "a vague tradition in the district" of its existence, which is a quietly remarkable thing: a sacred site so thoroughly faded that the surrounding community retained little more than the sense that something had once been there.

What makes Cloncagh unusual is not the absence of the well in isolation, but the concentration of sites in this small area. Within roughly a hundred metres, three holy wells are recorded. Lady's Well lies approximately forty metres to the north-north-east, and St Patrick's Well approximately a hundred metres to the east. The nameless well documented here falls between them, geographically and, it seems, in terms of surviving identity. All three sit in the shadow of an early ecclesiastical enclosure, the curving boundary of which survives some fifty metres to the north-north-east. Such enclosures, often circular or oval in plan, typically mark the earliest phase of an Irish Christian settlement, sometimes pre-dating any surviving church building by centuries. That three wells cluster around one suggests this landscape was once considered particularly sacred, with different dedications, perhaps different functions or feast days, organised around a single monastic or devotional centre.

There is little for a visitor to see in any conventional sense. The site is on private farmland, and the well itself has left no evident physical trace. Anyone with a serious interest in early Irish sacred landscapes might approach the area by first locating the ecclesiastical enclosure, which is the most archaeologically substantial feature recorded nearby. The record was compiled by Denis Power and uploaded to the national monuments database in August 2011, and the reference to Ó Danachair's 1955 fieldwork is the only documentary thread connecting this particular well to any human memory of it. That fragility, the fact that a place of presumed religious significance could dissolve so completely within living memory, is perhaps the most telling thing the site has to offer.
