Château des Ducs de Bretagne

The Château des Ducs de Bretagne stands at the edge of Nantes's old city, its massive circular towers and white-rendered walls enclosing a courtyard that has served as a ducal palace, royal residence, military barracks, and now a national history museum. Construction began in the late fifteenth century under Duke François II of Brittany and was continued by his daughter Anne, who later became Queen of France. The castle's outer ramparts, restored extensively in the early twenty-first century, form a free-access walkway that circumnavigates the entire site at height, offering unobstructed views over the Loire-Atlantique rooftops and the cathedral quarter. Within the courtyard stands the Grand Logis and the Tour de la Couronne d'Or, a slender Renaissance tower decorated with an ornate golden belt motif in carved stone. The Musée d'Histoire de Nantes, housed across multiple castle buildings, traces the city's history from medieval Brittany through the slave trade era, industrialisation, and into the twentieth century. Around 850 artefacts are on permanent display across thirty-two rooms, including maps, navigational instruments, Breton gold-work, and a vast mechanical clock. The slave trade galleries present Nantes's role as France's leading port in the triangular trade with unflinching historical detail. Temporary exhibitions regularly complement the permanent collection. Visitors can move freely between the courtyard, the rampart walk (always free), and the museum. Evening illumination of the towers makes the exterior photogenic from the Place Marc Elder esplanade. The castle is a five-minute walk from the central tram network and a short distance from the Cathédrale Saint-Pierre.
