The Popular center of remembrance is a former illegal detention center in Rosario, province of Santa Fe, Argentina. It was used by the provincial police between 1976 and 1979, during the Dirty War, to hold people with no formal charges and torture them, under the pretense of fighting radical left-wing political subversion and terrorism. Most of the detainees were in fact social activists, political dissidents, or merely relatives or acquaintances of people that were ideologically suspect in the eyes of the military junta of the self-styled National Reorganization Process.
The CPM occupies a corner of a large building that takes up a whole block in the city center, between Dorrego and Moreno and between Santa Fe and Córdoba St. It used to be the police headquarters, and during the Dirty War it was formally the home of an intelligence division of the provincial police.
