The Plages du Prado (or Plage du Prado—translated variously as Prado Beach,[1] Prado beach,[2] Prado Beaches,[3] and Prado beaches[4]) are the beaches in the south neighborhood of Marseille, France. The seaside park is an artificial coastal development created in the late 1970s by Gaston Defferre. They were built with the fill coming from the construction of the two Marseille subway lines.
