Madame Claude is a former brothel and now a bar in Berlin-Kreuzberg, which since 2008 regularly hosts different events such as concerts or parties. Based on the childhood dream of playing in an upside-down apartment, the decoration of Madame Claude's main room is a reconstruction of an apartment built upside-down, challenging the laws of gravity with furniture on the ceiling. The French founding trio also runs Club Marie Antoinette as well as Fitzroy.
