The Barbegal Mills: The Largest Concentration of Mechanical Energy in Antiquity

About 12 kilometers north of the town of Arles, within the Provence area of southern France, is the small city of Fontvieille. It’s a commune of simply 3,500 inhabitants who stay from agriculture and tourism, however till the fifth century AD it was additionally the place the place the best focus of mechanical vitality was present in all the historic world.

On the finish of the primary century A.D., a very powerful Roman hydraulic advanced was constructed there, consisting of two aqueducts and 16 mills, right this moment known as Barbegal. The 2 aqueducts joined simply north of the advanced, the place a lock managed the water provide to the mills, after which continued to provide the town of Arelate (right this moment’s Arles).

It’s recognized that the advanced remained in use throughout the 2nd and third centuries AD, after which regularly declined till its full destruction and abandonment within the fifth century, coinciding with the invasions that put an finish to the western empire.

Based on the archaeologist Fernand Benoit the advanced may have been constructed by the Gallo-Roman engineer Q. Candidius Benignus (Fifth Candido Benigno), who belonged to the Arelate carpenters corps and whose sarcophagus bears an inscription that claims: nobody surpassed him within the artwork of mechanical engineering and within the conduction of water programs .

As for the possession of the mills, Benoit believes that they in all probability belonged to the proprietor of the Roman villa close to La Mérindole.

At the moment there are necessary masonry stays of the water channels and foundations of a number of of the mills, along with the stepped channel that goes up the hill, which might be visited. On the Fontvieille vacationer workplace there’s a reconstruction of one of many water wheels, and on the Arles Museum you’ll be able to see a reconstruction of the entire.
