The Chronographe offers all residents of the metropolis a place where archaeology reveals a shared history and questions our perception of the territory. Located on the archaeological site of Saint-Lupien, it presents a discovery trail of Ratiatum, a Roman port in Gaul, dating from the 1st to the 3rd century.
As a tool for heritage promotion, it is also a place for exploration and experimentation in archaeology, thanks to an open program that encourages cross-disciplinary exchange. As a center for dissemination and awareness, it serves as a relay for metropolitan archaeological news.
