Otáčivé hlediště Český Krumlov, Open-air theatre in Český Krumlov, Czech Republic.

Otáčivé hlediště Český Krumlov is an open-air theatre featuring a circular auditorium that rotates 360 degrees during performances. The structure weighs about 650 tons and is powered by four electric motors to enable smooth transitions between different locations within the castle gardens.

Joan Brehms, a scenographer of Latvian origin, and Otto Haas, then director of the South Bohemian Theatre, launched the revolving auditorium in 1958 with a wooden turntable for about 60 spectators, turned by human power; the premiere on 9 June 1958 was Weisenborn's Lost Face. A 400-seat turntable followed in 1959, and in 1960 Brehms presented a 550-seat version driven by an electric motor and set into the ground. In 1994 the Škoda Plzeň-built auditorium replaced it: four 15 kW motors move 650 tonnes on a 21 m base for 644 spectators.

The revolving auditorium is operated by the South Bohemian Theatre from České Budějovice, whose drama, opera, ballet and puppet companies perform here from June to September, about eighty shows a season for some 55,000 spectators. The most-performed drama is A Midsummer Night's Dream with 318 performances, followed by Lucerna (270) and Beauty and the Beast (247).

The auditorium sits in the castle garden below the Bellarie summer house, with two narrow metal staircases cutting through the tiered rows. A white sign on the front row reads "VSTUP ZAKÁZÁN!". Performances run from June to September, about eighty a season, so seats are best secured ahead.

The audience does not watch from a fixed stage; instead, the entire seating area rotates with the scenes to reveal different viewpoints of the performance and surroundings. This unusual approach means each spectator experiences several completely different views of the environment during a single show.
