Built in 1928 as both a police station and jail, this building, which now houses one the city’s best museums, was under the Nazis one of the most notorious places of torture in the Third Reich. Now all five floors have been transformed into an exhibition using the original cells and charting the history of the little known about opposition to Hitler’s cronies from 1933 to 1945. At times gruesome, if you visit one museum whilst you’re in town make sure it’s this one. Please switch your mobiles off before entering.
