The Musée Maritime Fluvial et Portuaire tells the story of Rouen as a working port, not just a city of half-timbered lanes and Gothic churches. Models, photographs, ship equipment and river-trade displays explain how the Seine connected inland Normandy with the Channel and the wider Atlantic world.
It is a specialist museum, so it suits travellers who like industrial history, boats or the less polished edges of a city. The location west of the old centre also gives a useful excuse to see Rouen's modern riverside, where quays, warehouses and port infrastructure show a different side of town.
