Germany's second largest city, Hamburg is also known as the Gateway to the World. Its port, Europe's second largest, gave the city an important historic role. Hamburg became a member of the Hanseatic League in the Middle Ages and during the 19th and 20th centuries was an international business hub. The city was bombed heavily during World War II and during the 1960s, it was here that The Beatles got their start. From museums and galleries to beautiful architecture and gorgeous parks, there is plenty to see and do in Hamburg.
