The Bayerische Staatsoper is one of the most prestigious opera houses in the world. It has been the venue for major European premieres since 1700, including Wolfgang Amadeus Mozart's Idomeneo, re di Creta in 1781; four major operas of Richard Wagner (including Tristan und Isolde and two acts of his Opus Magnum Der Ring des Nibelungen) and Richard Strauss' Capriccio. Today, the Bayerische Staatsoper - together with the Bayerische Staatsorchester and the Bayerische Staatsballett - offers a dense repertoire of almost 350 opera and ballet performances a year.
