If any city can be said to have a ground zero, Vienna
can. Everything radiates from the great Gothic Stephansdom, St. Stephen’s Cathedral, that lies smack in the center of the Inner City, right in the historic quadrant that's included on UNESCO’s list of World Heritage sites. The cathedral’s rich, multicolored tile roof draws awes, as does an elaborate stone pulpit and the 18 altars in the main room alone. Notable figures entombed here include Holy Roman Emperor Frederick III and Prince Eugene of Savoy; the funeral of Antonio Vivaldi took place at this site as well. As they have for ages, Vienna’s famous Fiaker carriages stop just outside the main doors, waiting for passengers who want to tour the surrounding neighborhood.
