Unlike many Eastern European cities—nearby Dresden, for example—Prague was largely spared the demolition of World War II. The city was merely a province in the Austro-Hungarian empire, and mostly managed to avoid being rebuilt during the 18th and 19th centuries. The resulting abundance of baroque, Gothic, and Renaissance architecture makes the city a kind of open-air museum, especially around the Old Town area. Of course, a trip to Prague wouldn’t be complete without a stroll across the historic Charles Bridge to visit the city’s most impressive sight: Prague Castle.
