One of Germany's most historic palaces showcases years of Prussian history. In the Berlin-Pankow district, the Schloss dates from the 1660s, when it was the residence of Sophie Dorothea zu Dohna. Queen Elisabeth Christine, wife of Frederick the Great, used the palace as a summer residence from 1740 to 1797. Some of the living rooms have been faithfully reconstructed on the ground floor. From 1949 to 1960, Schönahsen was the seat of the first president of the DDR, and from 1964 to 1990, it was the residence for official guests of East Germany. On the upper floor, visitors can view the office of Welhelm Pieck and an exclusive suite reserved for visiting VIPs, including Fidel Castro and Indira Gandhi. The palace is one of the very few mammoth Berlin buildings that was not bombed in World War II.
