A collection of buildings cut through with covered passages and footbridges: archaeological remains from the Roman times to the Merovingian times, products from the Royal weapons factory (1688-1836), some documents on the foundation of Charleville, a pharmacy with 120 earthenware pots with blue decor, a reconstruction of the interior of an Ardennes house, some regional paintings from the 19 C and a room devoted to puppetry. A must-see, through a window, a mechanism by the Great Puppeteer.
