Prague is the capital of the Czech Republic. It's a city with a past that is rich in culture and history. Located in the center of Europe, it developed as a major trade and transportation center. During World War II, the city was not hit by any massive air raids, so a mix of architectural styles from different eras still remain in the city, including the Charles Bridge and Prague Castle. Some consider it a "museum of architecture." Prague's Old Town is a World Heritage Site.
