Go to Potsdam, a perfect place to relax from the hustle of the city, walking through the gardens and palaces. Southwest of Berlin, just over 25 km, it's the capital of the state of Brandenburg. It housed the splendor and decadence of the Prussian Empire until the Weimar Republic was established in 1919. The focus of Potsdam is Sanssoucci Park, Unesco World Heritage, which offers a complex of palaces and gardens, begun in the eighteenth century during the reign of Frederick the Great, expanded later in the nineteenth century. Remarks: The Sanssouci Palace, Rococo, made for the enjoyment of the King, a refuge for Frederick the Great's private life and where he could indulge his love of music.
