Vienna Walking Tour

St. Stephen's Cathedral (more commonly known by its German title: Stephansdom) is the mother church of the Roman Catholic Archdiocese of Vienna and the seat of the Archbishop of Vienna, Christoph Cardinal Schönborn, OP. The current Romanesque and Gothic form of the cathedral, seen today in the Stephansplatz, was largely initiated by Duke Rudolf IV (1339–1365) and stands on the ruins of two earlier churches, the first a parish church consecrated in 1147. The most important religious building in Vienna, St. Stephen's Cathedral has borne witness to many important events in Habsburg and Austrian history and has, with its multi-coloured tile roof, become one of the city's most recognizable symbols.

Following the enlargement of Vienna after the demolition of the city walls in the 1860s, the Hofburg had its last great expansion. An Imperial Forum (Kaiserforum) was planned, in which a two-winged structure reaching beyond the Ring Road, with the twin museums (Kunsthistorisches Museum and Naturhistorisches Museum) as flanks and terminating at the old Imperial Mews (the Hofstallungen, not to be confused with the much older Stallburg) of Fischer von Erlach. In 1913, the south-west wing, the New Castle (Neue Burg), was completed. However, the Imperial Forum was never completed and remains a torso. The New Castle wing today houses a number of museums (the Ephesos Museum, the Collection of Arms and Armour, the Collection of Ancient Musical Instruments, and the Museum of Ethnology) as well as some reading rooms of the national library. The Hofburg Congress Centre is also located here.

The Vienna State Opera (German: Wiener Staatsoper) is an Austrian opera house and opera company based in Vienna. It was originally called the Vienna Court Opera (Wiener Hofoper). In 1920, with the replacement of the Habsburg Monarchy by the First Austrian Republic, it was renamed the Vienna State Opera. The members of the Vienna Philharmonic are recruited from its orchestra. Probably the most-beloved symbol of Viennese arts, and one of the first buildings to be rebuilt in the postwar era. The first performance was Don Giovanni, an opera by Austrian native Mozart, on 25 May 1869. The architecture of the opera was barely tolerated by the picky Viennese when it opened. Van der Nüll did not take these criticisms of his work lightly and committed suicide. A few weeks later, von Siccardsburg died of a heart attack. Doubly cursed, the opera building succumbed to bombs less than 100 years later, during World War II. After ten years of Allied control after the end of the war, many cultural institutions reopened to celebrate the birth of the new Austrian state. This time the opera opened with an adopted son of Vienna's work: Beethoven's Fidelio. The lush curtains and overall elegance contribute to the atmosphere. Inexpensive standing room tickets are made available for every performance and sold the day of the performance. The line forms about two hours prior to the performance. Guided tours in a number of languages are offered. The line at the front side door forms about 1/2 hour before the tour.

The Natural History Museum Vienna (German: Naturhistorisches Museum Wien) is a large natural history museum located in Vienna and one of the most important natural history museums worldwide.
