The Memorial da Resistência de São Paulo (São Paulo Resistance Museum) is an institution dedicated to preserving the memory of the resistance and political repression of republican Brazil (1889 to the present day) by converting part of the building that housed, from 1940 until 1983, the São Paulo State Political and Social Order Department (DEOPS/SP), into a museum. DEOPS was one of the most violent political police forces in the country, specially during the military regime.

The long term exhibit consists of five modules: DEOPS; control, repression and resistance; Diorama; Cell 2 and Cell 4, which evoque the history of the Military Dictatorship.
