The Church of St. Leodegar was built in parts from 1633 to 1639 on the foundation of the Roman basilica which had burnt in 1633. This church was one of the few built north of the Alps during the Thirty Years War and one of the largest and art history rich churches of the German late renaissance period.
In the 8th century there was already an abbey consecrated to Saint Maurice on the current site of the church, which had been donated by Pepin the Short, and was known at the time as the Monastarium Luciaria. By the 12th century the abbey was under the jurisdiction of the Murbach Abbey, whose patron saint was St. Leodegar.
In 1291 the abbey was sold to the Habsburgs. In 1433 the city of Lucerne, no longer a member of the Eidgenossenschaft, took control of the abbey, and in 1455 it was converted from Benedictine to a “universal order” church.
The monastery experienced a heyday during the time of the reformation due to Luzern being a prominent city for the Swiss Catholic cantons. The papal nuncio, resident in Luzern, used the church as his cathedral during this time.
In 1874 the parish church of St. Leodegar was founded and with that the church became simultaneously a monastery church and parish church, as it is today.
References:Tyniec Benedictine abbey was founded by King Casimir the Restorer probably around 1044. Casimir decided to rebuild the newly established Kingdom of Poland, after a Pagan rebellion and a disastrous Czech raid of Duke Bretislaus I (1039). The Benedictines, invited to Tyniec by the King, were tasked with restoring order as well as cementing the position of the State and the Church. First Tyniec Abbot was Aaron, who became the Bishop of Kraków. Since there is no conclusive evidence to support the foundation date as 1040, some historians claim that the abbey was founded by Casimir the Restorer’ son, King Boleslaw II the Generous.
In the second half of the 11th century, a complex of Romanesque buildings was completed, consisting of a basilica and the abbey. In the 14th century, it was destroyed in Tatar and Czech raids, and in the 15th century it was rebuilt in Gothic style. Further remodelings took place in the 17th and 18th centuries, first in Baroque, then in Rococo style. The abbey was partly destroyed in the Swedish invasion of Poland, and soon afterwards was rebuilt, with a new library. Further destruction took place during the Bar Confederation, when Polish rebels turned the abbey into their fortress.
In 1816, Austrian authorities liquidated the abbey, and in 1821-1826, it was the seat of the Bishop of Tyniec, Grzegorz Tomasz Ziegler. The monks, however, did not return to the abbey until 1939, and in 1947, remodelling of the neglected complex was initiated. In 1968, the Church of St. Peter and Paul was once again named the seat of the abbot. The church itself consists of a Gothic presbytery and a Baroque main nave. Several altars were created by an 18th-century Italian sculptor Francesco Placidi. The church also has a late Baroque pulpit by Franciszek Jozef Mangoldt.
