Ochsenhausen Abbey was a Benedictine monastery was founded according a legend in the 9th century when there was a nunnery here called 'Hohenhusen', which was abandoned at the time of the Hungarian invasions in the early 10th century. A ploughing ox later turned up a chest of valuables buried by the nuns before their flight, and the monastery of Ochsenhausen was founded on that spot.
The first Abbey Church of Ochsenhausen was in fact dedicated in 1093. The monastery was initially a priory of St. Blaise's Abbey in the Black Forest, but gained the status of an independent abbey in 1391. In 1495 it became Reichsfrei (territorially independent).
The abbey was secularised in 1803 and in 1806 its territories were absorbed into the Kingdom of Württemberg.
Much of the buildings still survive. They were extensively refurbished in the Baroque style. The Baden-Württemberg State Youth Music Academy is accommodated in part of them. The former abbey church is now the parish church of St. George's.

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.
