The Maréchaussée (Marshalsea), whose name was derived from the fact that it was directly under the orders of the Marshals of France, became the «Gendarmerie nationale» (national constabulary) in 1791. The rooms display the uniforms, equipment and weapons of the «gendarmes» (constables) through the ages and how they have been represented in popular culture (as puppets, lead figurines or china models, etc.)
