> Or maybe it's just coincidence, or was just common to shape buildings that way for a long time. They share an outline common to many palaces from the 18th to the mid 19th century. See for example also the palace of Mannheim that (in part) houses the University of Mannheim and was built roughly at the same time as Prinz-Heinrich-Palais: https://de.wikipedia.org/wiki/Schloss_Mannheim#/media/Datei:SchlossEhrenhof_2017.jpg https://de.wikipedia.org/wiki/Schloss_Mannheim#/media/Datei:... When you look closer, you can observe that the individual architectonic elements are quite distinct: Frederician Rococo[1] in Berlin vs Rundbogenstil (round-arch style)[2] with a later (1900s) large extension in Neoclassical[3] style in Munich.
