Finkenstein Castle was first mentioned in 1142. It was owned by the Dukes of Carinthia who gave it to their ministeriales, who called themselves after the castle von Finkenstein. In 1223 there was a dispute between Heinrich von Finkenstein and Bishop Henry of Bamberg, the owner of the nearby castle Federaun regarding the crossing of the river Gail. After the extinction of the Carinthian Finkensteins at the beginning of the 14th Century, the ownership was passed back to the Dukes of Carinthia, which had been the Habsburg since 1335. Emperor Maximilian I, Duke of Carinthia since 1493 gave the castle and the rule to his liegeman Sigismund von Dietrichstein, whose descendants held the castle still 1861. Since the end of the 18th century, it is no longer inhabited and decayed, only ruins remain.
The oldest parts of the castle are Romanesque. In the second half of the 16th century, was rebuilt in late Gothic style. At the beginning of this century, four gates were built in the High Castle. The 15 m high end wall of the former palace still stands today.
Today Finkenstein Castle Ruin is the backdrop of the Burgarena, an amphitheatre with 1150 seats mainly used for concerts.

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.
