The museum, situated in one of the Parisian police stations, is dedicated to the history of police, and exhibits photographs, letters, memorabilia, and drawings, as well as items connected to famous criminal cases and characters, prisons, and daily life. There are also waxworks of policemen in uniforms, old weapons, and a guillotine.
Among other items are the relicts from World War II, such as German machine guns and insignias worn by Jews, and other objects that reflect major events in the history of France (including conspiracies and arrests). The museum also includes a car park, bus park and information available in different languages, although a lot of the documentation is only in French. There is no admission fee, but it is asked that you make a donation.
