The Douala Maritime Museum is thus part of a vast programme to collect, preserve and showcase the cultural heritage of the Cameroonian coast and to revive its history in order to know and better understand the Cameroonian maritime landscape and its evolution over the years. Its collections cover a variety of themes relating to:

Man in his natural environment, the evolution of types of ships in the world and in the Cameroonian ports and the history of trade and its development in the Cameroonian ports.
