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.
[2] 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 new stage covers 2,500 square metres (3,000 sq yd), and is thus the world's third largest, after the Opéra Bastille in Paris and the Grand Theatre, Warsaw.
[5] It opened on 21 November 1963 with an invitation-only performance of Die Frau ohne Schatten under the baton of Joseph Keilberth.
[6] During its early years, the National Theatre saw the premieres of a significant number of operas, including many by German composers.
