Delve into the histories of Potsdam and nearby Berlin by visiting landmarks that help define these remarkable cities. Potsdam is renowned for its imperial past, as you will discover while passing through the Dutch and Russian quarters that were constructed following the orders of various Prussian kings. To enhance your understanding of Prussian royal history, you will pause for photos of the Palace of Sanssouci – King Frederick the Great’s summer residence – and Cecilienhof, the last palace constructed before Prussia was dissolved. More must-see attractions await you in Berlin, such as the somber Holocaust Memorial and the Reichstag, the domed Neo-Renaissance building where the lower house of Germany’s legislature meets. You will also enjoy up-close views of a remnant of the Berlin Wall, the former border crossing Checkpoint Charlie and the Brandenburg Gate, the iconic symbol of a once-divided Germany. A look at the 17th-century Charlottenburg Palace reveals more about the Prussian royals’ passion for architecture.
