Mühltroff castle was probably in the 10th to 11th centuries to strengthen the rule of German Emperor, the knights to protect against attacks by the Sorbs with their fixings mortgaged founded. In 1357 the Plauen bailiffs had to hand over the castle to the Wettin margrave brothers Balthasar and Wilhelm , who then enfeoffed various vassal families with it. In 1380 the castle was burned down in the Guttenberg feud.
From 1949 to 1989, the castle, which was made public property of the GDR , was used as a residential building until it came back into Mühltroff's possession after the fall of the Berlin Wall. It was sold privately in 1999 as the only part of the castle and contains modern apartments.
As the cultural center of the place, the castle, which can be visited during guided tours, offers rooms for a wide range of club and exhibition activities as well as a wide range of events, with the 'black kitchen' being particularly worthy of mention.
The castle was founded as a low castle on a green stone cliff as a round defense and watch tower surrounded by moats , around which residential and farm buildings and a manor were built over the centuries.
The main building of the castle dates from the 16th and 17th centuries, when a lot was built. Remodeling took place after the fire in 1817 and the castle tower was redesigned between 1820 and 1837 and 1856.

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.
