Theater 11, Performance venue in Oerlikon, Switzerland

Theater 11 is a multipurpose hall at the corner of Wallisellenstrasse and Thurgauerstrasse in Oerlikon, built 1962–1965 to plans by Karl Egender and opened on 14 January 1966 as Stadthof 11. Its large hall seated about 1000 for concerts, 860 for opera and 760 for banquets, and its floor could be raised in three stepped sectors. A 24-metre stage tower with a classic proscenium stage, side and rear stages and a sinking orchestra pit for 80 musicians rises above the two-storey hall.

The venue reopened in 2006 following extensive renovations and launched with the Swiss premiere of the musical We Will Rock You. Since then it has established itself as a major destination for musical theater productions in the city.

The name Stadthof 11 comes from the city district 11, created in 1934 from Oerlikon, Schwamendingen, Seebach and Affoltern. Opened in 1966, the house has no public subsidy and lives on touring productions, mostly musicals; the 2006 reopening was with We Will Rock You.

The main entrance with its cantilevered canopy is on Thurgauerstrasse, shared with the Züspa hall; a side exit leads to Birnbaumstrasse. The restaurant has its own entrance at the southeast corner, at the Wallisellenstrasse crossroads. The hall seats about 1000 in concert layout, 860 for opera and 760 at banquets.

The 24-metre stage tower rises above the hall, and the main stage is a proscenium over 24 metres wide with side and rear stages and a lift stage. The orchestra pit can be lowered to hold 80 musicians, and the stage tower has 36 fly lines, 6 rear lines and 4 panorama lines.
