This magnificent private mansion dates back to the 17th century and was home to Le Havre-born navigator Michel-Joseph Dubocage de Bléville in the 18th century. One side of the building features a striking slate and timber-framed façade, while the other is made of brick and black flint. This stunning contrast certainly catches the eye. Today, the mansion houses a museum dedicated to the history of Le Havre and its port, with exhibitions and collections that show how central maritime trade has been to the city’s growth. An entire room is dedicated to Michel-Joseph Dubocage de Bléville, a prominent navigator and merchant who, aboard his ship La Découverte, sailed all the way to China and helped establish one of the first maritime trade agreements between France and China. That treaty gave a major boost to Le Havre’s economy. After nine years at sea, he returned home and bought this mansion to settle down. Don’t miss the chance to visit the museum. The city owes a great deal to this pioneering sailor!
