Musée Subaquatique de Marseille

This guide to the Musee Subaquatique de Marseille follows Antony Lacanaud, the local diver who saw an underwater sculpture garden near Cancun in 2017 and decided the city needed one of its own. It traces how sculptor Christophe Charbonnel's Poseidon and Evelyne Galinski's Nereides came to rest on the seabed off Plage des Catalans, and why every figure is cast from cement mixed to let barnacles and sponges settle without harm. The sculptures sit five meters down, invisible from the beach above.
