Longchamp Palace was conceived in 1839 in honor of the construction of the Marseille Canal, with which the city intended to make up for the constant lack of water. However, it began to build almost 30 years later. Address: Longchamp Boulevard. The palace complex consists of three parts: in the center there is a fountain - a real water castle, semicircular colonnades lead from it to the north and south - this is the Museum of Fine Arts (Musee de Beaux-Arts) and the Museum of Natural History (Musee d'Histoire Naturelle).→
