Sanssouci is a historical building in Potsdam, near Berlin. Built by Prussian King Frederick the Great as his summer palace, it is often counted among the German rivals of Versailles. While Sanssouci is in the more intimate Rococo style and is far smaller than its French Baroque counterpart, it, too, is notable for the numerous temples and follies in the surrounding park. The palace was designed and built by Georg Wenzeslaus von Knobelsdorff between 1745 and 1747 to meet Frederick's need for a private residence where he could escape the pomp and ceremony of the royal court. The palace's name is a French phrase meaning "without worries" or "carefree", emphasising that the palace was meant as a place of relaxation rather than a seat of power.

Potsdam is the capital and largest city of the German state of Brandenburg. It is part of the Berlin/Brandenburg Metropolitan Region. Potsdam sits on the River Havel, a tributary of the Elbe, downstream of Berlin, and lies embedded in a hilly morainic landscape dotted with many lakes, around 20 of which are located within Potsdam's city limits. It lies some 25 kilometres southwest of Berlin's city centre. The name of the city and of many of its boroughs are of Slavic origin.
