Many people come to Vienna to soak in the classical architecture and history. However, Vienna's underground crypts, sewers, tunnels and cellars offer a different type of Austrian experience. The crypts of St. Michael's Church (shown here) and the cellars, sewers and passageways under the adjacent Michaelerplatz are worth a look because of their atmosphere and the role that they played in Vienna’s past. The famous Orson Welles movie "The Third Man" was filmed in tunnels and drainage sewers just like the ones that tourists are led through today. Some underground tours also visit Baroque-era wine cellars (complete with bottles) and even some sites that have been excavated in search of Roman ruins and relics.
