Killaspugbrone (Irish: Cill Easpaig Bhróin, meaning 'the church of Bishop Brón')[1] is an early Christian church on the coast west of Sligo town and near the modern resort of Strandhill. Known as Caiseal Irrae in the earliest references. One of the earliest churches in Sligo, it was founded by Bishop Brón mac Icni (died 512) a contemporary of St. Patrick. The church is in a townland and civil parish of the same name.[1]
