Český Krumlov Castle dates back to 1240 when the first castle was built by the Witigonen family, the main branch of the powerful Rosenberg family.
By the 17th century the Rosenbergs had died out and the dominion of Krumau was given to Hans Ulrich von Eggenberg by Emperor Ferdinand II and Eggenberg was named Duke of Krumau. After the death of Hans Ulrich's son, Johann Anton I von Eggenberg, the castle was administrated for the period between 1649 and 1664 by his widow Anna Maria.
One of her two sons, Johann Christian I von Eggenberg, was responsible for the Baroque renovations and expansions to the castle including the castle theatre now called the Eggenberg Theatre. When the male line of the Eggenbergs died out in 1717 the castle and duchy passed into the possession of the Schwarzenbergs. In 1947, the Schwarzenberg property, including Český Krumlov, was transferred to the Czech provincial properties and in 1950 it became the property of the Czechoslovak State. The entire area was declared a national monument in 1989 and in 1992 it was added to the UNESCO World Heritage List.
The castle houses the Český Krumlov Baroque Theatre, which is situated on the castle courtyard. It is one of the world's most completely preserved Baroque theatres with its original theatre building, auditorium, orchestra pit, stage, stage technology, machinery, coulisses (stage curtains), librettos, costumes etc.
References:The Clementinum is a historic complex of buildings in Prague. 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.
