The Burgtheater (Court Theatre), originally known as K.K. Theater an der Burg, then until 1918 as the K.K. Hofburgtheater, is the Austrian National Theatre in Vienna and one of the most important German language theatres in the World. The Burgtheater was created in 1741 and has become known as "die Burg" by the Viennese population; its theatre company of more or less regular members has created a traditional style and speech typical of Burgtheater performances.
The theatre opened on 14 March 1741, the creation of the Habsburg Empress Maria Theresa of Austria who wanted a theatre next to her palace. Her son, Emperor Joseph II called it the "German National Theatre" in 1776. Three Mozart operas premiered there: Die Entführung aus dem Serail (1782), Le nozze di Figaro (1786) and Così fan tutte (1790). Beginning in 1794, the theatre was called the "K.K. Hoftheater nächst der Burg". Beethoven's 1st Symphony premiered there on 2 April 1800.
