The Fort d’Entrecasteaux, a listed 17th century historical monument, was built under Louis XIV at the same time as Fort Saint Jean which faces it. It was built as much to protect the city of Marseille as “against” the people of Marseille in order to keep an eye on a population that was often resistant to the King’s orders. This exceptional site overlooking the Old Port of Marseille and covering 5 hectares, is now being offered a second life in a reconstruction “for” and “with” the inhabitants of the city. With its 350 years of history and its place at the heart of a port city on the move, it must now become one of Marseille’s top tourist attractions, a place of both memory and transformation. Our activity report bears witness to this.
