The site lies on the south bank, close to Tetunny Graveyard, where a hollow in the rock face collects water from a modest spring. Despite its relative obscurity today, evidence of continued devotion can still be found; visitors tie strips of cloth to the surrounding bushes as tokens when performing “rounds”, the traditional practice of circling a holy well whilst praying.

The well remains entirely untouched by human construction, with no masonry or artificial additions disturbing its natural setting. Positioned roughly twelve feet above the river’s normal level, the site was documented in 1946 with particular concern for its future, as plans for raising the water level threatened to submerge it completely. The observer noted that whilst the well saw fewer pilgrims than in previous times, the presence of cloth offerings showed it hadn’t been forgotten by local people maintaining their spiritual traditions.

This type of natural holy well represents one of Ireland’s most ancient forms of sacred site, where Christianity merged with much older water veneration practices. The dedication to St. Brighid, one of Ireland’s patron saints, likely replaced an earlier association with the goddess Brigid, demonstrating the continuity of sacred landscapes through changing belief systems. The simple act of tying cloth to nearby vegetation connects modern visitors to centuries of pilgrims who sought healing, blessings, or simply a moment of reflection at this unadorned spring in the Donegal countryside.
