Monastery of Santa Clara is presided by nuns of the order of the Poor Clares. It was founded in 1358, but ruined in war in 1458. In 1460 the buildings were repaired and church rebuilt. During the War of Independence, the community was forced to leave the monastery, which suffered pillage and destruction by French troops.
The church was built in Gothic style. It has Baroque style altarpieces from the 17th century, as well as the organ from 1799.
The Clementinum is a historic complex of buildings in Prague. 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.
