The Crau is composed of two different parts: The dry Crau is in the south, and has been used as pasture from Roman times.
The wet Crau is in the north and includes the communes of Saint-Martin-de-Crau, Eyguières, Istres, Mouriès, and Arles.
It produces the Crau hay, which benefits from an Appellation d’origine contrôlée The Crau was described by Strabo as the Stony Plain (Book IV Chapter 1).
