History+
The castle's origins date back to 1152, when Robert I, Count of Dreux, received the area as an appanage from his father Louis VI. He commissioned the construction of the rectangular moated castle with sides measuring 55 meters, featuring four corner towers and four additional towers at the entrances and on the east and west walls. In the 14th century, Joan of Évreux, the widow of Charles IV, resided in the castle until her death in 1371. She had the complex expanded and a chapel installed in the Saint-Jean Tower. Later, it served as a residence for Louis de Valois, the brother of King Charles VI. During the Hundred Years' War, the Château was besieged and captured multiple times by English troops. From the 15th century onwards, the castle, which belonged to the royal domain, was assigned as a residence to deserving nobles.
