Karls kühne Gassenschau is in the widest sense a Swiss circus, variété or street theatre, as of April 2016 based in Winterthur.
The show was founded in 1984 and started as classical street performance act. In 1999 the crew toured with the Swiss national Circus Knie, and thenafter more than more fixed installation were preferred.
There's no man called Karl that initiated the cabaret. Karls kühne Gassenschau, meaning Charles' keen side street show, was founded as a street theatre of a bunch of wild street performers.
Some present Swiss acts and personalities, among them Ursus & Nadeschkin respectively Nadja Sieger, and Sandra Moser started their career as part of the show.
The multimedial supported artistic shows, focussed on large installations as a seasonal theme, usually are fixed at locations for one theatre season, sometimes as the present since 2014 in the municipality of Winterthur and St-Triphon, some years ago in Wallisellen or at the so-called Saffa-Insel on occasion of the Zürcher Theater Spektakel. Karls kühne Gassenschau attracts up to 500,000 spectators a year.
