Learn all about one of the most beautiful cities in the world on this walking tour in Vienna. The tour starts with Roman Vienna and the question of why a castle was built here. Visit St. Michael's Church, Vienna's third oldest church with a combination of 3 different architectural styles. Learn all about the Hofburg Palace and the significance of the huge grounds covering 555,000 m². You will also discover details about the most important rulers in the city. Be impressed by the size of Heroes' Square and what lies behind the facades. Discover why any trip to Vienna should include a visit to the Imperial Treasury, what there is to see in the city, and things that you probably would have missed without your tour guide. As you walk past the Austrian National Library with its state room, you will find out what the symbol on the roof means and why the square is named after Emperor Joseph II. Visit the church where many Habsburg weddings took place (closed on Sundays and public holidays) and discover why the groom was not even present at some weddings. However, the city's history has also seen some dark times. As you walk past the Albertina and the Monument Against War and Fascism, you will be confronted with the horrors of the Second World War. You will also stop at the State Opera and find out why the Hotel Sacher now stands in place of the Carinthian Gate Theatre. You will be surprised about what anecdotes there are on the Providentia Fountain at Neuer Markt and on the Habsburg burial ritual in the Imperial Crypt.
