Enjoying UNESCO World Heritage status for its gorgeous parks and palaces, Potsdam is located just southwest of Berlin. The Prussian rulers of the House of Hohenzollern, Germany’s later emperors, used Potsdam as a garrison and royal residence. Suffering less damage than Berlin during the Second World War, the city hosted the famous Potsdam Conference at Cecilienhof Palace which shaped postwar Europe. At the "Bridge of Spies," KGB agent Rudolph Abel was exchanged for the U2 pilot Gary Powers during the Cold War. Explore these historic sites, the 18th century city center, and, of course, Frederick the Great's Sanssouci Palace. ​​
