The Bavarian State Opera or the National Theatre (Nationaltheater) on Max-Joseph-Platz in Munich, Germany, is a historic opera house and the main theatre of Munich, home of the Bavarian State Opera, Bavarian State Orchestra, and the Bavarian State Ballet.

During its early years, the National Theatre saw the premières of a significant number of operas, including many by German composers. These included Wagner’s Tristan und Isolde (1865), Die Meistersinger von Nürnberg (1868), Das Rheingold (1869) and Die Walküre (1870), after which Wagner chose to build the Festspielhaus in Bayreuth and held further premières of his works there.

During the latter part of the 19th century, it was Richard Strauss who would make his mark on the theatre in the city in which he was born in 1864. After accepting the position of conductor for a short time, Strauss returned to the theatre to become principal conductor from 1894 to 1898. In the pre-War period, his Friedenstag (1938) and Capriccio were premièred in Munich. In the post-War period, the house has seen significant productions and many world premieres.

First theatre – 1818 to 1823
The first theatre was commissioned in 1810 by King Maximilian I of Bavaria because the nearby Cuvilliés Theatre had too little space. It was designed by Karl von Fischer, with the 1782 Odéon in Paris as architectural precedent. Construction began on 26 October 1811 but was interrupted in 1813 by financing problems. In 1817 a fire occurred in the unfinished building.

The new theatre finally opened on 12 October 1818 with a performance of Die Weihe by Ferdinand Fränzl, but was soon destroyed by another fire on 14 January 1823; the stage décor caught fire during a performance of Die beyden Füchse by Étienne Méhul and the fire could not be put out because the water supply was frozen. Coincidentally the Paris Odéon itself burnt down in 1818.

Second theatre – 1825 to 1943
Designed by Leo von Klenze, the second theatre incorporated Neo-Grec features in its portico and triangular pediment and an entrance supported by Corinthian columns. In 1925 it was modified to create an enlarged stage area with updated equipment. The building was gutted in an air raid on the night of 3 October 1943.

Third theatre – 1963 to present
The third and present theatre (1963) recreates Karl von Fischer's original neo-classical design, though on a slightly larger, 2,100-seat scale. The magnificent royal box is the center of the interior rondel, decorated with two large caryatids. The new stage covers 2,500 square meters (3,000 sq yd), and is thus the world's third largest, after the Opéra Bastille in Paris and the Grand Theatre, Warsaw.

Through the consistent use of wood as a building material, the auditorium has excellent acoustics. Architect Gerhard Moritz Graubner closely preserved the original look of the foyer and main staircase. It opened on 21 November 1963 with an invitation-only performance of Die Frau ohne Schatten under the baton of Joseph Keilberth. Two nights later came the first public performance, of Die Meistersinger von Nürnberg, again under Keilberth.
