Berlin
This top Northern European hotspot is simply bristling with sights to see such as the Brandenburg Gate, Potsdamer Platz, the Berlin Wall, Check Point Charlie and the Reichstag. When you add in the myriad of night life venues, cafe culture and restaurant scene - your holiday will cover all bases for a memorable city break. At the end of World War II, both Germany and Berlin were divided into four zones of occupation under the control of the United States, Britain, France and the Soviet Union.
