The Rue du Moulin, which connects the Place Ducale to the current museum dedicated to Arthur Rimbaud, lies at the heart of the new principality founded by Charles de Gonzague, then Duke of Mantua, Peer of France, and Governor of Champagne. It was with characteristic modesty that he named it Charleville in 1608. Each pavilion bore the name of the town that had contributed to its construction: Reims, Sainte-Menehould, Langres, Suippes, Rethel, Mouzon, Mézières, and so on. A plaque on the Sainte-Menehould pavilion commemorates a restoration of the building in 1830. And it is in this building, at number 33 Rue du Moulin, that Christophe Melin opened, right in the heart of this historic town, the restaurant "La Clef des Champs" and the bed and breakfast "Côté Chambres."
