Built at the end of the 15th century by François II, the last Duke of Brittany and then by his daughter, Anne of Brittany, the castle of the Dukes of Brittany bears witness to six centuries of history. Its medieval fortress protects a residential building with refined facades that blends different styles into a harmonious whole. In addition, the château houses the Nantes history museum, with a very contemporary setting and entirely open to the public.
