Meunerie romaine de Barbegal, Ancient Roman watermill complex near Fontvieille, France
The Meunerie romaine de Barbegal is an archaeological site near Fontvieille featuring the remains of two parallel rows of watermills built into a hillside. Water from an aqueduct flowed down through channels to power the wheels, with stone structures still visible showing how the system was organized.
The mills were built in the 2nd century and became one of the ancient world's largest industrial sites. The complex operated for several centuries before gradually being abandoned as Roman power declined in the region.
The site reveals how Romans harnessed water power to feed large populations, with the layout still showing where grain was ground into flour daily. The channels and stone bases visible today remind visitors of this industrial purpose that once served the city of Arles.
The site is open to visitors year-round and requires sturdy shoes for walking across uneven stone remains. There is minimal shade on the hillside, so bringing water and sun protection is advisable.
This facility generated more mechanical power than any other known Roman structure through its innovative water wheel system. The concentrated energy production here demonstrates an engineering capability that would not be matched again for over a thousand years.
