was used as a bedroom for companions and guests. The blue and white theme is continued throughout on the palace's window shutters, it seems, in deference to the Bavarian heritage of then crown princess Elisabeth. Between 1835 and 1840 the explorer and world traveler Alexander von Humboldt was invited and stayed in the tent room during the summer months. Charlottenhof Park The landscape architect Peter Joseph Lenné was charged with the design of the Charlottenhof gardens. He completely recreated the originally flat and partly marshy area into an English garden with trees, lawn and water features. He also linked the new park at Charlottenhof to the older one at Sanssouci from the time of Frederick the Great. World Heritage Site Since 1990, Charlottenhof Palace has been part of the UNESCO World Heritage Site "Palaces and Parks of Potsdam and Berlin". The palace is administered by the Stiftung Preußische Schlösser und Gärten Berlin-Brandenburg.
