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:The Clementinum is a historic complex of buildings in Prague. Until recently the complex hosted the National, University and Technical libraries, the City Library also being located nearby on Mariánské Náměstí. The Technical library and the Municipal library have moved to the Prague National Technical Library at Technická 6 since 2009. It is currently in use as the National Library of the Czech Republic.
Its history dates from the existence of a chapel dedicated to Saint Clement in the 11th century. A Dominican monastery was founded in the medieval period, which was transformed in 1556 to a Jesuit college. In 1622 the Jesuits transferred the library of Charles University to the Klementinum, and the college was merged with the University in 1654. The Jesuits remained until 1773, when the Klementinum was established as an observatory, library, and university by the Empress Maria Theresa of Austria.
