Returning from a trip to Italy, Friedrich Wilhelm III (r 1797–1848) commissioned Karl Friedrich Schinkel to design this petite summer refuge modelled on a villa in Naples. Today, the minipalace is a sparkling backdrop for masterpieces by such Schinkel-era painters as Caspar David Friedrich and Eduard Gaertner as well as by the sculptor Christian Daniel Rauch. Ground floor rooms brim with original Biedermeier furniture.
