The Barbegal aqueduct and mills was a Roman watermill complex located on the territory of the commune of Fontvieille, Bouches-du-Rhône , near the town of Arles , in southern France. The complex has been referred to as "the greatest known concentration of mechanical power in the ancient world " and the 16 overshot wheels are considered to be the largest ancient mill complex.
30-573: Another similar mill complex existed on the Janiculum in Rome , and there are suggestions that further such complexes existed at other major Roman sites, such as Amida (Mesopotamia) . The Barbegal site is located 12 kilometres east northeast of Arles near Fontvieille , where the Arles aqueduct passed near a steep escarpment. The mills consisted of 16 water wheels in two parallel sets of eight descending

There are substantial masonry remains of the water channels and foundations of the individual mills, together with a staircase rising up the hill upon which the mills were built. The mills operated from the beginning of the 2nd century until about the end of the 3rd century. The capacity of the mills has been estimated at 4.5 tons of flour per day, enough to supply bread for as many as 10,000 or perhaps even 30–40,000 inhabitants of Arelate at that time. It
120-422: A sufficiently large working area, but only 2.6 m between their axle centres, which must have reduced efficiency due to turbulence between them. The southern race had one larger wheel. The site resembles Barbegal , although the excavations show that they were undershot rather than overshot in design (i. e. with the stream entering at the bottom of the wheel, not the top). The mills were still in use in 537, when
150-570: A time signal. This tradition goes back to December 1847, when the cannon of the Castel Sant'Angelo gave the sign to the surrounding belltowers to start ringing at midday.

240-468: Is possible that the mills at Barbegal may also have been used for sawing timber and stone when not grinding wheat. The Hierapolis sawmill from the 3rd century AD shows a crank-activated frame saw being used in this way, and another has been excavated at Ephesus . Visitors to Barbegal may park where a minor road (Route de L’Aqueduc) crosses the massive remains of the original aqueduct, and, with olive orchards on either side, walk south about 250 meters along

The Roman aqueducts that fed the mills were also built to supply water to the town of Arles (then called Arelate ). The two aqueducts joined just north of the mill complex and a sluice controlled the water supply to the complex. Vertical water mills were well known to

In the limited excavated area, two mill races branched obliquely off the Aqua Traiana, turned to run parallel to the aqueduct for some distance, and then turned back to feed into the aqueduct again. It appeared that the northern mill race had 3 or 4 millwheels of 2.30 m diameter and width about 1.65 m to provide
