The site has an interesting history. The former Stadtschloss suffered serious destruction during WWII ( https://en.wikipedia.org/wiki/City_Palace,_Berlin ) and the Communist East tore it completely down to build the Palace of the Republic https://en.wikipedia.org/wiki/Palace_of_the_Republic,_Berlin and acted as the hub of DDR government. Once the wall fell, and DDR disintegrated, in 2008 DDR's Palace of Republic was almost completed demolished, and work on new Stadtschloss which very much resembles the original commenced.
