Opernhaus Dortmund

Opernhaus Dortmund is the opera house of Dortmund, Germany, operated by the Theater Dortmund organisation. A new opera house opened in 1966, replacing an earlier facility which opened in 1904 and was destroyed during World War II. It was built on the former site of the Old Synagogue, which was demolished by the Nazi local government in the 1930s.

Architects Heinrich Rosskotten and Edgar Tritthart designed the modernist structure. The design separates the functions of the stage and technical areas in the Bühnenhaus (stage house), which is dominated by straight lines, from the auditorium under a concrete shell roof.
