Claro abbey was founded in 1490 on the initiative of Scolastica de Vincemalis, a Benedictine religious of Milan who on 13 May 1490 became the establishment's first abbess. The monastery grew rapidly, and by 1516 was home to 16 nuns. In 1559, the religious were charged by decree of Pope Paul IV to relaunch and supervise Seedorf Abbey in the Canton of Uri. Intended for the education of girls, the buildings were enlarged several times during the 17th century, and again in the second half of the 20th century.

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.
