Both avant-garde and historical, Berlin is the capital and a cultural center of Germany. A bustling nightlife and art scene pairs with historical monuments such as the Berlin Wall, Brandenburger Tor (Brandenburg Gate), the Reichstag, and the Jewish Memorial. While you're there, check out the Pergamon Museum full of classical antiquities as well as the Neuses Museum, which contains Egyptian relics. The Deutsche Guggenheim should be next on your itinerary to bring you into the world of modern art. Also, if you're into the communist history, visit the DDR Museum.

The U-Bahn can get you around the city to all of the sites if you haven't booked one of the common city tours. Also, Berlin is making great progress towards becoming more bicycle-friendly.
