What makes it quietly arresting is not the well itself but what surrounds it: rows of small statues of the Blessed Virgin, a nearby cairn of dry stone with a double-lintelled opening in its eastern face packed with coins and buttons left by visitors over generations, and a whitethorn bush and ash tree enclosed by a tumbled wall just two metres to the north. The stream that rises close by carries the name Sruthán na Naomh, the stream of the saints, and it once ran south-west to drive a horizontal mill on the edge of the Oughtmama ecclesiastical enclosure.

The well is dedicated to St Colman Mac Duagh, a sixth-century monk who, according to tradition, trained under St Enda on Inis Mór before seeking greater solitude in the Burren around 590. He is said to have lived for a time in a cave on the far side of Slievecarran, to the south-east, where a church and a second well also bear his name. His story eventually carried him beyond Clare entirely: the legendary Connacht king Guaire is said to have granted him land at Kilmacduagh in County Galway, where a monastic site still bears his name today. The association with the Oughtmama complex, which lies just below the well to the south-west, adds a further layer; the site there is also believed to have connections with a Colman, though which one remains uncertain.

The well appeared on Ordnance Survey maps as early as 1842, named Tobercolman, and has clearly been a place of active devotion for a very long time. The coins and buttons pressed into the cairn opening are a common feature of holy well practice in Ireland, a small physical act of petition or thanksgiving that accumulates quietly over decades. The views west from this spot take in the wider valley and the old church remains below, so the place works on several registers at once: as a spring, a shrine, a landmark, and a reminder of just how densely layered the Burren's spiritual geography remains.
