If only the mighty walls of Chateau de Chastellux could talk! But seeing they can't, inquire if tours are available to hear a couple of its fascinating tales instead.
You'll find this fortified complex in Chastellux-sur-Cure. Once you've seen everything you want to at Chateau de Chastellux, take a look at nearby Chateau de Bazoches, and Le Musée Archéologique.
