The well is correctly named Tobar Cáillín, dedicated to St Cáillín, and the landscape immediately surrounding it preserves a complete set of devotional features that remain in active use. Alongside the modest cross and scattered offerings at the water's edge, two stone settings in the surrounding ground mark out a ritual circuit that has not simply survived but continued.

The well was recorded as early as 1684, when the Connacht historian Roderic O'Flaherty noted it, a reference later reproduced by Hardiman in 1846. Immediately to the south-west of the spring lies a penitential station, a subcircular arrangement of stones roughly three and a half metres across with a small cairn in its western quarter. About twenty metres to the north-north-east is a larger oval setting of stones known as St Cáillín's Bed, its grassy interior scattered with the small pebbles that pilgrims carry and count during the rounds. A "round" at a holy well is a traditional penitential practice involving a set number of circuits made on foot, often combined with prayers at each station along the way. Here, seven such rounds are performed at this station and at the others on the 13th of November, the feast day of the saint. The persistence of that date, and of the specific number seven, suggests a continuity of observance that stretches back well before O'Flaherty put pen to paper.
