Weimar is above all a cultural city: Goethe, Schiller, Herder, Liszt, Bach, van de Velde and Gropius - all of them and many others left their mark here, not only in the city, but also in the Russicher Hof, an integral part of the history of the City. In 1999, Weimar was also the cultural city of Europe. The Weimar Bauhaus has been a UNESCO World Heritage Site since 1996, and in 1998 the Weimar Classic Ensemble was added to the World Heritage List. In 2008, the city celebrated with numerous events the work of Johann Sebastian Bach, who came to Weimar 300 years ago. In 2011, the city celebrated the 200th birthday of the composer Franz Liszt, who lived and worked in Weimar for 10 years. The German National Theater is a historic place. Here the Weimar Republic was proclaimed and many operas, e.g. the Lohengrin by Richard Wagner, premiered.
