This unimposing little tower is all that remains of a sprawling mansion on the edge of the city walls built in 1369 by Jean Sans Peur (John the Fearless), the Duke of Burgundy. He ordered the tower built in 1409 as an extension of the house—his bedroom was here—and then the defensive turret after he arranged the assassination of the king's brother during the Hundred Years' War. The second-floor vaulted ceiling resembles a leafy tree, a masterwork of medieval architecture. Kids will enjoy the climb up to see the restored red velvet latrine, considered state-of-the-art in its time. Don't forget to pick up the brochure in English at the front desk.
