The history of the Gadagne site dates from the early 1st century B.C. (- 76 B.C.) even before the founding of Lugdunum by the Romans. It is the first confirmed tracing of pre-colonial settlement in this sector on the right bank of the Saône.

The presence of craftsmen plus the construction of a warehouse at the beginning of the 1st century of our era bear witness to the district’s commercial vocation.

During the 3rd century, important refurbishment works lead to a complete reorganisation of the building.

This expansion may correspond to the development in the transportation of merchandise on the Saône and the probable existence of an unloading bay close by.

The warehouse was consequently transformed, either in full or in part, into dwellings. This final occupation phase drew to a close with the creation of a hypocaust – an ancient Roman underground heating system.

The site was abandoned in the early part of the 5th century. It served as a rubbish dump before suddenly being buried beneath the rubble of a landslide.
