St Patrick is the patron saint of Ardpatrick, and indeed the area derives its name from the saint. It is believed that St Patrick founded a church on the hill of Ardpatrick in the 5th century and a monastery was built on the hill in the following century.
A story in the late 9th century work Bethú Phátric,
The Tripartite Life of St Patrick, tells us that when Patrick sought a
site for the church on Ardpatrick, Derbhall, the local leader, opposed
him. He told him that he would believe only if St Patrick removed part
of the mountain wall to the south so that he could see Loch Long in the
land of Fir Muí Féinne. St Patrick prayed and the mountain
melted forming a gap, Bealach Leáite, the Pass of the Melting.
