The Riesenrad
This ferriswheel in the Prater Amusement park was made famous in the movie, The Third Man, as the site of Orson Welles' famous quote of, "in Italy for 30 years under the Borgias they had warfare, terror, murder, and bloodshed, but they produced Michelangelo, Leonardo da Vinci, and the Renaissance. In Switzerland they had brotherly love - they had 500 years of democracy and peace, and what did that produce? The cuckoo clock. So long Holly."
