The practice of hanging rags, or clooties, at holy wells is one of the older acts of devotion in the Irish landscape, the cloth understood to carry a prayer or an ailment away from the person who tied it. That this one still receives such offerings, however infrequently, gives it a quiet persistence that sets it apart from the many wells that have fallen entirely out of use.

The well appears on the 1840 Ordnance Survey map under the anglicised name Toberreendoney, a rendering of the Irish Tobar Rígh an Domhnaigh, meaning the Well of the King of Sunday. The fuller Latin form recorded by the Ordnance Survey in 1838, fons regis Sabbathi, confirms that the surveyors understood and translated the name. The title is an unusual one; the King of Sunday is a poetic epithet for Christ, and its attachment to this particular spring places the well within a Christian devotional tradition, even if the practice of leaving rags at water sources is considerably older. The 1838 Ordnance Survey Namebook entry for Ballingarry Parish notes the well's position to the west of Clochanavarra. Caoimhín Ó Danachair, the folklorist who recorded its details in 1955, found the rounds still being made at that point, though with diminishing regularity.

The well sits in a small grove of whitethorn trees whose branches lean directly over the water, creating the kind of enclosed, low-ceilinged space that makes such sites feel separated from the surrounding land. Rounds at holy wells typically involve a set number of circuits made on foot, often accompanied by prayers, and are observed on particular feast days in the local calendar. If you are in the area around Ballingarry and want to locate it, the 1840 map reference and the position west of Clochanavarra are the most reliable guides. The rags on the bushes, if any have been left recently, will signal that you have found the right place.
