Aqueduc de Fontenay

The Fontenay aqueduct, also known as Aqueduc du Cher, is a largely underground aqueduct that helped supply water to the ancient city of Caesarodunum (now Tours), alongside springs, wells, and another intramural aqueduct. It owes its most common name to a locality near Bléré, where its starting point was located, some 25 kilometers east-southeast of Tours, close to a main spring; the water table from which it springs is still exploited in the 21st century. The aqueduct was also fed by several smaller springs along the way. The aqueduct's route followed the Cher valley along its left bank, totally or partially embedded in the limestone hillside, except a few engineering structures required to cross valleys, almost in a straight line between Bléré and Saint-Avertin, a commune bordering Tours from which it is separated by the Cher. Although a large part of its route is attested, it has not been possible to identify its course beyond Saint-Avertin, in an area that has been profoundly altered by urbanization, which still casts doubt on its final destination and even on the premature interruption of its construction. It was built during the Early Roman Empire, probably in the 1st century AD, at the same time as the main public monuments of Caesarodunum. It underwent regular maintenance and repairs until it was abandoned at an uncertain time that seems to predate the High Middle Ages
