The Château des ducs de Bretagne is a 15th-century fortress and residence located in the historic heart of Nantes. It serves as the primary municipal history museum, housing over 1,150 artifacts documenting the city's role in the Atlantic slave trade, the World Wars, and industrial transformation. The complex features a mix of defensive military architecture and flamboyant Gothic and Renaissance residential façades. A notable architectural element is the golden crown-shaped spire atop the Grand Gouvernement building. The castle remains surrounded by a moat that has been drained and repurposed into public green space. Visitors can walk the elevated rampart path for panoramic views of the Nantes skyline. The site has functioned as a museum since 1924, following its status as a listed historical monument. It acts as the final residence of the Dukes of Brittany before the region's integration into the French crown.
