A holy well that once drew visitors to pray, drink its waters, and leave small offerings has been filled in by the local authority. The steps are gone, the basin is gone, the painted noticeboard is gone. The only surface trace is the name of the house opposite, which still carries the saint's dedication, a quiet residue of something that mattered to people for a very long time.

The well was dedicated to St Brigid, one of Ireland's three patron saints, and local tradition held that she drank from it on her way to Kildare, where she founded her famous monastery. Holy wells associated with Brigid are common across Ireland, functioning as places of devotional practice where pilgrims would pray, drink the water, and leave votive offerings. When the folklorist Caoimhín Ó Danachair documented this one in 1958, it was still in active use. He described a roadside structure set below road level, reached by a flight of steps, with water piped into a basin resembling a stone mortar, a niche containing a small statue of the saint, and a painted board reading "St. Brigid pray for us." Small religious objects had been left there by visitors. By August 1978, when heritage fieldworker Henry Wheeler visited and photographed it for an OPW field report, the picture had changed considerably. The basin was nearly dry and neglected, the noticeboard had disappeared, and the saint's statue was obscured by overgrowth. No offerings remained. The well appeared on every edition of the Ordnance Survey six-inch map under its familiar name, but its working life as a place of living devotion had already quietly ended.

The site sits roughly 590 metres west of Rathcoole's Church of Ireland church and graveyard, in what was described in 1978 as a cul-de-sac between the north side of the village and the Naas Road. There are no visible surface remains today, so a visit is less about seeing than about knowing. Photographs taken by Ó Danachair are held in the National Folklore Collection at UCD and are accessible through the Dúchas digital archive, giving some sense of what the structure looked like before it was lost.
