Marseille, France. Longchamp Palace With A Cascading Fountain, 1869 Stock Photo

The Palais Longchamp is a monument in the 4th arrondissement of Marseille, France. It houses the city's musée des beaux-arts and natural history museum. The surrounding park (the Parc Longchamp) is listed by the French Ministry of Culture as one of the Notable Gardens of France. The Palais Longchamp was created to celebrate the construction of the Canal de Marseille, which was built to bring water from the Durance River to Marseille. Although the foundation stone was laid by the Duke of Orleans on 15 November 1839, the building took 30 years to complete, partly because of the enormous expense and partly because of difficulties with local regulations. Designed by the architect Henry Esperandieu, the building was centered on the structure and elaborate fountain known as the chateau d'eau (water castle).
