The former Jesuit Church (Église des Jésuites) is the parish church is the main Roman Catholic church of Molsheim and the principal 17th-century church building in the Rhine Valley. The church was built between 1615 and 1617 by the German architect Christoph Wamser, and consecrated on 26 August 1618. Molsheim's Jesuit church is considered one of the foremost examples of Gothic Survival architecture or, as it is called in German, de:Nachgotik (posterior Gothic).
Among the many features inside the richly ornate building, the Baroque Saint Ignatius' Chapel (1621–1630) in the north transept and the Rococo Our Lady's Chapel (1748) in the south transept stand out as the most visually striking. Another pride of the church are the 1781 pipe organ by Johann Andreas Silbermann and the monumental Late Gothic cross (1480) from the former Carthusian monastery of the town.

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.
