The monument

Set in the historic heart of Nantes, the Château des ducs de Bretagne is the city’s most important historic building, along with the Cathedral St. Pierre.


When looking at it from the city, it is a fortress with 500 metres of curtain walls punctuated by seven towers, all linked by a sentry walkway.


The inner courtyard reveals an elegant 15th century ducal residence made of tufa stone, in flamboyant gothic style and bearing the first traces of Renaissance inspiration, as well as other buildings dating back from the 16th and the 18th centuries. With their elegant white stone walls and sophisticated sculpted façades, they contrast strikingly with the rough textures of the exterior fortifications, made of granite blocks and separated by layers of schist.
