Predigerkirche is one of the four main churches of the old town of Zürich. First built in 1231 as a Romanesque church of the then Dominican Predigerkloster, the Basilica was converted in the first half of the 14th century, the choir between 1308 and 1350 rebuilt, and an for that time unusual high bell tower was built, regarded as most high Gothic edifice in Zürich.
The abbey-choir building had been used for secular purposes since the 16th century Protestant Reformation, and was transformed by the installation of shelves into a warehouse building. For several centuries it was used as a granary. Since 1914 the choir building has been administrated by the Zentralbibliothek (Zürich central library), the main library of both the canton, city and the University of Zürich.

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.
