Le Musée de la Préfecture de Police
Crime buffs will enjoy this museum hidden on the second floor of the 5e arrondissement's police station. Although the exhibits are in French only, the photographs, letters, drawings, and memorabilia pertaining to some of the city's most sensational crimes are easy enough to follow. Among the 2,000-odd relics you'll find a guillotine, old uniforms, and remnants of the World War II occupation—including what's left of a firing post, German machine guns, and the star insignias worn by Jews.
