In 2012 the Deutsche Oper in Berlin had its centennial celebrations. Although today’s building was not opened until 1961, the history of the house on the Bismarckstrasse goes further back: it was built in 1912 and opened as Deutsches Opernhaus upon the initiative of a group of people from Berlin–Charlottenburg as the citizen’s opera in opposition to the Königliche Hofoper, now Staatsoper Unter den Linden. The film illustrates all facets of the different eras of this Berlin opera institution from the beginnings until today through interviews with artists closely connected to the Deutsche Oper Berlin as well as a large variety of archive footage that also includes documentations of rehearsals and performances from the last 100 years.
