In the 13th century, the San Juan del Hospital Church was the priory of the Knights of the Order of St. John of Jerusalem with a hospital attached and it was converted into a military parish in the 18th century. Built around 1261, it is considered to be the first church built after the Christian conquest. Its combination of the synthesis and elegance of Romanesque tradition with the new gothic architecture and the fact that it has the only cemetery dating from medieval times in Valencia, led to its classification as a National Historic and Artistic Monument in 1942.

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.
