The Château de Châteaubriant in the Loire-Atlantique département of western France is said to be haunted by the ghost of Françoise de Foix, one of the most tragic figures of the French Renaissance. Françoise was a noblewoman who became the mistress of King François I around 1518. When the king's attention turned to other women, Françoise's husband, Jean de Laval, lord of Châteaubriant, took a terrible revenge — he imprisoned her in a room of the castle, keeping her confined for years. She died in 1537, reportedly from poisoning ordered by her jealous husband. Since her death, the room where she was imprisoned has been associated with supernatural phenomena. Visitors describe hearing a woman's weeping emanating from the room, seeing bloodstains that reappear on the floor no matter how many times they are cleaned, and feeling an overwhelming sense of confinement and despair. The château, which spans both medieval and Renaissance architectural periods, sits in a commanding position above the town. Françoise's ghost is said to walk the grounds at night, dressed in the fine clothing of a Renaissance noblewoman, her face pale and her expression one of unresolved anguish. The legend has been part of Breton folklore for nearly five centuries.
