Forced to sell or hand over their possessions to local families, they retreated to a bog roughly 750 metres to the north, where they continued to live in hiding. That waterlogged refuge acquired a name that stuck: Moin na mbrathar, the bog of the brothers. It is a quietly telling detail about how religious communities survived suppression in early modern Ireland, and it sits in sharp contrast to the solidity of the friary they left behind, whose walls still rise to considerable height above the undulating grassland north of Kilconnell village in County Galway.

The friary was founded in 1353 by William O'Kelly, most likely on or near the site of an earlier monastery associated with St Conall. It was reconstructed in 1414 and, in 1464, adopted the Observantine reform, a movement within Franciscan life that sought a return to stricter poverty and discipline. By 1617, when a formal inquisition catalogued the property under James I, the complex was considerable: three acres containing a chapel, a council chamber, a library, a hall, a storehouse, four chimnied chambers, twenty-eight dormitory cells, four gardens, three orchards, a cemetery, sixty ash trees, a mill, a watercourse, and four acres of arable land adjoining the house. The physical remains today reflect that accumulated complexity. The 15th-century nave and chancel church, 37.5 metres long, was extended with a south aisle, a south transept, and a three-storey tower, probably all late 15th-century additions. The O'Donellan chapel, opening off the east wall of the transept, came later still. Inside, several elaborately carved canopied tomb-niches survive, along with traceried windows from the 15th and 16th centuries, and two piscinas, small stone basins used for disposing of water from liturgical washing, set into the walls. Of the cloister, only the east and south sides remain, along with ruined traces of the domestic east range, which included a Guardian's House and a granary.

The site is accessible from Kilconnell village, and the scale of what survives repays a slow circuit. The carved stonework in the tomb-niches is particularly fine, and the west doorway through which the church is entered gives a good sense of the quality of craftsmanship brought to bear on successive phases of building. Three probable holy wells lie nearby, and the surrounding field system is also recorded as part of the wider monument.
