This is the pattern, or patron, associated with Saint Sorney's Well at Drumacoo, a ritual observance in which people have traditionally come seeking cures for injuries, bleeding, and minor disabilities. The pattern is a distinctly Irish form of devotional practice, typically tied to the feast day of a local saint and involving prescribed circuits, prayers, and sometimes the leaving of offerings at the water's edge. At Drumacoo, those offerings are still visible today.

The well itself is a carefully made structure. A roughly circular spring well, stone-lined and sunken into the ground, measures about 1.7 metres across and is enclosed within a larger circular stone wall roughly four metres in diameter. Seven steps descend to the water from the north. It sits some 35 metres to the south-west of the medieval church at Drumacoo, a proximity that suggests a long-standing relationship between formal ecclesiastical space and older, more intimate devotional practice. A cross-inscribed water-rolled limestone pebble was recorded here by Higgins in 1987, the kind of small portable object that accumulates meaning over generations of use, a personal act of marking made on a stone shaped by water rather than by a mason's hand.

The well is dedicated to St Sorney, a figure whose cult is strongly localised to this part of County Galway. Visitors approaching from the church will find the well a short distance across the ground to the south-west, and the seven descending steps give the place an unexpected sense of depth and enclosure once you are standing at the water.
