Break the secrets of the Dombes Côtière

13 km of galleries linked Lyon to Château de Miribel. A Roman heritage that is one of the peculiarities of the Dombes Côtière.

The sarrasinieres is a subterranean passage located on the edge of the old Rhone valley. They would have allowed it to circulate on foot or would have served as an aqueduct. Although there are few remains, it is known that they followed a 13 km long track, divided into 2 parallel vaulted galleries running from Lyons to Miribel Castle via Neyron. The name "Sarrasiniere" would come from "Cesarinieres", galleries built by the Romans after the victory of Julius Caesar over the Helvetians to complete the defense system elaborated during the war of Gaul.
