Palaces and Parks of Potsdam and Berlin (German: Schlösser und Gärten von Potsdam und Berlin) are a group of palace complexes and extended landscape gardens located in the Havelland region around Potsdam and the German capital of Berlin. The term was used upon the designation of the cultural ensemble as a World Heritage Site by UNESCO in 1990. It was recognized for the historic unity of its landscape—a unique example of landscape design against the background of monarchic ideas of the Prussian state and common efforts of emancipation.
