Schattenburg castle was mentioned in the chronicle by the monks Ortlieb and Berthold in 1138. Muntifurt Castle, mentioned in the first half of the 12th century, may have housed vassals of the Earl of Bregenz, who ruled over the area at the time. At his coming to power (1182) the Earl Hugo I, the grandson of the last Earl of Bregenz Rudolf (1150), repositioned his residence to Feldkirch Castle, important for reasons of power politics and the control of traffic.
For 200 years, the Castle remained the property of the Earls of Montfort. Upon the death of the last of the Montforts, Rudolf IV (1390), the castle and the power that came with it passed to the Habsburgs. The Habsburgs ruled the estate through governors who lived in the Castle until 1773.
Only from 1416 until 1436 was their rule briefly interrupted, when it came into the hands of the Earls of Toggenburg. Duke Friedrich of Austria’s help in the flight of the antipope Johannes XIII turned out to be fatal for him. Not only was he outlawed in the name of the Emperor and excommunicated, he also lost all is possessions, among which Feldkirch. In 1825 the City bought the partially ruined Castle from the state for 833 Guilders. Today Schattenburg is a museum.

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.
