The Monastery of Roussanou was founded in the middle of the 16th century. Compared to other rocks where monasteries were built, the one of Roussanou has a lower elevation, which makes it more accessible. The monastery was initially founded by monks and it suffered severe damage during World War II. It became a convent in 1988. The beautiful wall-paintings of the Catholicon were executed in 1560, when the priest-monk Arsenios was the abbot of the monastery. The unknown hagiographer seems to have been a very skilful artist and successfully follows the Cretan School style.

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.
