Potsdam is the capital of Brandenburg and borders Berlin. The town has a population of approx. 175,000. It is widely known for its castles and landscape as a World Heritage Site. Potsdam is more than 1000 years old. Many historic buildings are under re-construction after World War II and the period of the GDR.
Located about 30 km southwest of the capital, Potsdam was used as a residence for the kings of Prussia when they wanted to get away from the big-city trouble (and potential rabble-rousers) in Berlin, and in a way it still has a similar function, as many well-to-do people from Berlin have either moved here or have bought a second residence here since reunification in 1990. Potsdam also serves as the capital of the Bundesland of Brandenburg, after an attempt to reunite Berlin and Brandenburg in a single Bundesland failed in the early 1990s.
