Walk through Potsdam center (~10km) gives the impression of a strange mixture of the styles across all European history. Interesting condensation. Roman Baths in various classical Roman and antique Italian styles, St. Nicholas' Church in the Classicist style, Sanssouci in Rococo style, mixed with some modern buildings and Sozialistischer Realismus. All in one.
