The Monastery of San Paolo d'Argon was a Benedictine monastery decorated by premier painters of the late-Baroque era. The monastery was initially founded in the 11th century. It was reconstructed in the 16th century to take on the present layout with two cloisters. The design is attributed to Pietro Isabello. The frescoes (1624) in the refectory were painted by Giovanni Battista Lorenzetti.
Starting in 1684, the church was reconstructed by the architect Domenico Messi. He also designed the marble façade was begun in 1688.

Until recently the complex hosted the National, University and Technical libraries, the City Library also being located nearby on Mariánské Náměstí.

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.
