The complex of mills bear parallels with a similar complex at Barbegal in southern Gaul built in the first century AD, although the Barbegal mills have not been built upon at later times, and are thus extremely well preserved.
Twelve kilometers north of Arles, at Barbegal, near Fontvieille, where the aqueduct arrived at a steep hill, the aqueduct fed a series of parallel water wheels to power a flourmill.
