Northern Germany includes the states of Germany that border on the North and Baltic Seas. These states are popular tourist destinations for their beaches and gentle rolling, windswept hills. The Hanseatic city-states of Hamburg and Bremen are also rich in history and energy. Historically Protestant, the region shares much in common with the neighboring Netherlands and Denmark giving its cities a very cosmopolitan and modern flair. Hamburg is Germany's most wealthy city as well. The countryside is home to many a beautiful dairy farm and in certain rural areas one can still hear the Low German and Frisian languages being spoken.
