St Audeon's Catholic Church

St Audoen's Catholic Church is a Catholic church, sited on High Street Dublin Ireland beside the similarly named and much older St. Audoen's Anglican Church on Cornmarket.

The Church was built between 1841–1846 and was designed by Patrick Byrne who also designed the nearby St. Paul's Arran Quay.

The church has its portico added in 1893 by G.C. Ashlin to relieve the external facade. Until 1880 it had a central dome positioned over the crossing of the nave but it collapsed and was replaced by a flat ceiling. The interior is lit by lunette windows cut into the massive black calp walls. These walls are best appreciated from Cook Street from where their sheer bulk dominates the area and the city walls. Because of its steeply sloping site, the church has a double level crypt to the rear.

Until December 2007 the church hosted a regular traditional Latin Mass. The church has experienced a resurgence of attendance due to the influx of Polish immigrants who regularly celebrate mass in their native language.
