The well, known in Irish as Tobar Laichtin, dedicated to the patron saint of Achadh Ur, is fed by a large spring that once bubbled up with enough force to attract regular gatherings of the faithful, shaded by a large aged ash tree. By 1839, when the Ordnance Survey Letters recorded its details, the ritual life of the place was already being described in the past tense, the result of an episcopal intervention that had suppressed devotional practices across the entire Diocese of Ossory.

The suppression itself is slightly murky in the historical record. The OS Letters of 1839 attribute the prohibition to Dr. Marum, Roman Catholic Bishop of Ossory, who abolished the custom of performing Stations at the well every Saturday, along with similar practices elsewhere in the diocese. Stations, in this context, meant a sequence of prayers and ritual movements carried out at a sacred site, a practice with deep roots in Irish popular devotion. A separate source from 1891 credits a Dr. Kinsella as the bishop responsible for banning pilgrimages at the well. Whether the suppression happened in a single act under one bishop or was reinforced across successive administrations is unclear, but the effect was the same: a well that had drawn weekly gatherings fell quiet. By the time of the 1839 description, the writer noted that old people could remember the Stations from roughly fifty years prior, placing the prohibition somewhere around the end of the eighteenth century.

When the site was visited in 1987, it had been enclosed by a relatively recent wall, and local understanding still held it to be a holy well, episcopal decree notwithstanding. The persistence of that identification, across nearly two centuries of official discouragement, says something about how quietly these places hold their significance.
