The Rio de Janeiro Civil Police Museum was founded in 1912, under the name of Crime Museum with the idea of collecting objects to the investigations and to serve as an auxiliary measure of learning for the Police Academy.
Throughout the years, the museum collected documents and objects produced through police work, divided, today, into the following sections:
- institution of the police force and its history,
- uniformed police in the former federal capital,
- technical police,
- the extinct political police,
- initial communications,
- forbidden games,
It contains an important ethnographic collection on Afro-Brazilian cults from the beginning of the 20th century, extremely well preserved and proclaimed IPHAN National Trust in 1938, by the direction of the museum.
It is registered under the International Council of Museums as a Brazilian scientific museum with headquarters in the 1910 French eclectic style building, projected by famous architect Heitor de Mello.
