69290 Craponne

The Gallo-Roman lake of the Yzeron, located in Craponne (Auvergne-Rhône-Alpes), is an ancient ramified work of the 1st century BC, feeding Lugdunum in water from the basin of the Yzeron. Its remains, like the turrets, bear witness to complex hydraulic engineering.

69005 Lyon

The remains of the so-called Angélique aqueduct reservoir, located in Lyon, are a key element of the Gallo-Roman Gier aqueduct, 86 km long, feeding Lugdunum in water from the Pilat massif.

Aqueduc gallo-romain
69005 Lyon 5ème

The Gier aqueduct, built under the Roman Empire in Lyon 5th, is the longest (85 km) of the four ancient aqueducts feeding Lugdunum. Its remains, partially classified, illustrate a masterpiece of hydraulic engineering between the Loire and the Rhône.

Aqueduc
69440 Saint-Didier-sous-Riverie

The Grand Bozançon aqueduct bridge, located in Saint-Didier-sous-Riverie in Auvergne-Rhône-Alpes, is an emblematic hydraulic structure of this region. Its exact construction period remains undetermined.

69700 Givors

The old Givors Canal, built between 1763 and 1839, connected Givors to Rive-de-Gier via 29 locks and 5 water bridges. This 18th-century industrial monument, now partially destroyed, illustrates the rhônalpine river engineering for the transport of coal and goods.
