It fell into decay at the end of the 13th century, and in ruins, the Catholic Monarchs eliminated it and included it into S. Martín Pinario. In 1495, Gómez de Marzoa´s efforts to set up a college for poor students led to the monastery becoming Compostela´s first school and the origin of Galicia´s Renaissance University. The Order of benedictine nuns occupied it as of 1499.

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.
