The Burgtheater, originally known as K.K. Theater an der Burg, then until 1920 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 theater company of more or less regular members has created a traditional style and speech typical of Burgtheater performances.
It was created on 14 March 1741 by Habsburg Empress Maria Theresa of Austria to be a theatre next to her palace, and 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". The theatre was moved to a new building at the Ringstraße on 14 October 1888 designed by Gottfried Semper and Karl Freiherr von Hasenauer.
