Vienna, Austria: The Ringstrasse

Vienna's historic center is encircled by a road called the Ringstrasse. In the 1860s, Emperor Franz Joseph I of Austria had Vienna's medieval walls torn down and replaced with this grand boulevard. Today, the three-mile loop is lined with many of Vienna's top sights; hop aboard one of the trams that traverse the Ringstrasse for a DIY, budget tour of the city.
