Baroque symmetry
The central axis of the palace lies precisely on the axis of the Solitudeallee avenue. The arched passage to the basement level in turn lies exactly at the center of the palace and forms the entrance to the apartment on the basement level. It is designed as a large oval room with four pillars and massive foundation walls that bear the White Hall and its cupola above. The walls are decorated with reliefs that depict the glory of war and the arts in the form of trophies.
