The Theater an der Wien (The Theatre on the Wien River) is a historic theatre in Vienna, originally designed in the Empire style. It was created by the Viennese theatrical impresario Emanuel Schikaneder, who is best known as Mozart's librettist and collaborator on the opera Die Zauberflöte which premiered in 1791. The theatre opened on 13 June 1801 with a prologue written by Schikaneder, followed by a performance of the opera "Alexander" by Alexander Teyber.
