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:Varberg Fortress was built in 1287-1300 by count Jacob Nielsen as protection against his Danish king, who had declared him an outlaw after the murder of King Eric V of Denmark. Jacob had close connections with king Eric II of Norway and as a result got substantial Norwegian assistance with the construction. The fortress, as well as half the county, became Norwegian in 1305.
King Eric's grand daughter, Ingeborg Håkansdotter, inherited the area from her father, King Haakon V of Norway. She and her husband, Eric, Duke of Södermanland, established a semi-independent state out of their Norwegian, Swedish and Danish counties until the death of Erik. They spent considerable time at the fortress. Their son, King Magnus IV of Sweden (Magnus VII of Norway), spent much time at the fortress as well.
The fortress was augmented during the late 16th and early 17th century on order by King Christian IV of Denmark. However, after the Treaty of Brömsebro in 1645 the fortress became Swedish. It was used as a military installation until 1830 and as a prison from the end of the 17th Century until 1931.
It is currently used as a museum and bed and breakfast as well as private accommodation. The moat of the fortress is said to be inhabited by a small lake monster. In August 2006, a couple of witnesses claimed to have seen the monster emerge from the dark water and devour a duck. The creature is described as brown, hairless and with a 40 cm long tail.
