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 ancient Argos Theater was built in 320 BC. and is located in Argos, Greece against Larissa Hill. Nearby from this site is Agora, Roman Odeon, and the Baths of Argos. The theater is one of the largest architectural developments in Greece and was renovated in ca 120 AD.
The Hellenistic theater at Argos is cut into the hillside of the Larisa, with 90 steps up a steep incline, forming a narrow rectilinear cavea. Among the largest theaters in Greece, it held about 20,000 spectators and is divided by two landings into three horizontal sections. Staircases further divide the cavea into four cunei, corresponding to the tribes of Argos A high wall was erected to prevent unauthorized access into the theatron and may have helped the acoustics, but it is said the sound quality is still very good today.
Around 120 CE, both theaters were renovated in the Roman style.
