This castle belonged to the Lords of Sully.
One of their descendants, Georges de la Trémoille, chamberlain to Charles VII, received the wounded Joan of Arc in the castle on 8 September 1429.
The aim was to keep her under surveillance while Charles VII discreetly tried to get closer to the Duke of Burgundy. It was the Duke of Burgundy who would later deliver the Virgin to the English
But it was Maximilien de Béthune who would remain her most famous owner. He acquired the Château de Sully sur Loire in 1602 with the fortune of his wife, Anne de Courtenay, and the money he had
accumulated as financial director of the kingdom of Henri IV, who made him Duke of Sully. Close to the latter, he designed the King's Chamber in his château (see picture). After his death, the
château passed to his heirs for three centuries.
The other famous person who stayed at the Château de Sully sur Loire was François Marie Arouet, the famous Voltaire. The philosopher of the Enlightenment was exiled to Sully on two occasions, in
1716 and 1719, after he spoke out about the incestuous love affair between the regent Philippe d'Orléans and his daughter, the Duchess of Berry.
