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:House of the Blackheads (Melngalvju nams) is a building situated in the old town of Riga. The original building was erected during the first third of the 14th century for the Brotherhood of Blackheads, a guild for unmarried German merchants in Riga. Major works were done in the years 1580 and 1886, adding most of the ornaments.
The structure was bombed to a ruin by the Germans June 28, 1941 and the remains demolished by the Soviets in 1948. The current reconstruction was erected from 1995 to 1999. Today the House of Blackheads serves as a museum and sometimes concert hall.
