Potsdam is the capital and largest city of the German state of Brandenburg. It directly borders the German capital, Berlin, and is part of the Berlin/Brandenburg Metropolitan Region. It is situated on the River Havel some 25 kilometres southwest of Berlin's city centre.
Potsdam was a residence of the Prussian kings and the German Kaiser until 1918. Its planning embodied ideas of the Age of Enlightenment: through a careful balance of architecture and landscape, Potsdam was intended as "a picturesque, pastoral dream" which would remind its residents of their relationship with nature and reason.
The city which is over 1000 years old is widely known for its palaces, its lakes, and its overall historical and cultural significance. Landmarks include the parks and palaces of Sanssouci, Germany's largest World Heritage Site, as well as other palaces such as the Orangery Palace, the New Palace, the Cecilienhof Palace, or the Charlottenhof Palace.
