This curious double island in the middle of a lake has a long history dating as far back as 1218, only 3 years after the Magna Carta was signed in England.
Having seen many reincarnations through cycles of destruction and reconstruction, Sully-sur-Loire has known many famous guests including Joan of Arc, Voltaire and King Louis XIV.
You can take a guided tour of the chateau (although only in French), or on a self-guided tour in multiple languages. There are focus tours and workshops about architecture and the daily lives of the castle’s former inhabitants for kids.
