Considering the Kyriad Marseille in Marseille?

The Greco-Roman harbor today by JLBG
Inside the Musée d'Histoire de Marseille (museum of history of Marseille), in the "Jardin des Vestiges" (Garden of remains), the wall across the picture was the main quay of the harbor and the lawn is instead of the seawater. It dates back to the Ist century AD. It began soon to silt up and at the end of the Vth century, was completely full. Check with the small scale model on the previous picture.
