Stadtschloss, Berlin City Palace in 1860

Sadly, this structure didn't survive the damage of World War II. The Berlin City Palace was heavily damaged during the war and ultimately razed in 1950 by the German Democratic Republic (East Germany). The Germany reunification led to calls for reconstructing the palace and it is expected that by 2019, an approximate reconstruction should be near completion.
