The Abbey of Saint-Jean Orbestier was founded in 1107. Nine centuries later it is still as imposing abbey church which has survived the abandonment of history, it is hard to imagine how the Benedictine monks have shaped the land and the local economy from this abbey.
In 1251 the first fire, whose origin remains unknown, ravaged the monastery. In 1340, the beginning of the Hundred Years War, British troops set fire to the new abbey. Two centuries later, the Wars of Religion caused the third destruction in 1569 and 1570. Protestants and Catholics fought over the land resulting in fire, looting and the confiscation of income and land.
In the 17th and 18th centuries, despite different modes of management and recovery efforts, the abbaye declined with the owners of the Abbey, the Diocese of Lucon declaring the permanent closure of the monastery in 1769. During the Revolution, the abbey was sold as national property. The church roof collapsed in 1912.
Today the church is restored.

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.
