Guided tour of the Roman aqueduct of Gier

Built by the Romans to supply Lyon with water, the Gier aqueduct can be visited in Mornant, with several sections accessible. Present in both the form of a bridge and an underground tunnel, discover its construction and operation.

At 86 km, it is the longest aqueduct leading to Lugdunum, capital of the Three Gauls during the Gallo-Roman period. It originated in Izieux in the Loire department, at the foot of the Pilat massif, thanks to a water intake on the Gier River. Several remains are still visible today, particularly in the commune of Mornant. At the Mornantet site, you will discover a complete arch and a pillar, all covered with the "opus reticulatum" facing. The visit continues with the canal, which at this point begins its underground passage through the village.
