The maritime museum has been located since 1958 in one of the finest fortresses on the French coast, one that has walls surviving from Gallo-Roman fortifications of the 3rd century ad, but which is largely the work of Sebastien, Marquis de Vauban (1633-1707) from the late 17th century. The museum displays are accommodated in three towers, the Tour Madeleine, the Portail Paradis and the Keep. Displays relate to ship building, weapons used in naval warfare and navigational instruments. A large section called Tresors d’oceans (treasures from the oceans) displays artefacts recovered by marine archaeologists. Brest was one of the French ports principally concerned with trading to the Far East, and the museum also accommodates a section deal with the city’s East India Company.
