The construction was begun by François II, the last Duke of Brittany, and then continued by his daughter Anne de Bretagne, who was twice Queen of France. The fortress also contains a residential palace with fine façades and Renaissance loggias. Inside the ducal palace is the historical museum, with its very contemporary decor. The 850 exhibits, together with many multimedia items, invite you to immerse yourself in the extraordinary history of Nantes, the capital of the Dukes of Brittany, the place where the Edict of Nantes was signed under Henri IV, a major Atlantic port for trade with the colonies and the slave trade from the 17th century onwards, a flourishing industrial city in the 19th and 20th centuries, and today a cultural and artistic metropolis. To conclude your visit, treat yourself to a break in the restaurant located in the tower known as the Vieux Donjon (the old keep) or do a bit of shopping in the souvenir and bookshop.
