This museum, which displays a splendid collection of mosaics, is designed as a showcase both of the archaeological site and of the current Rhône and Vienne. Start at the museum to get an insight into the remains and the organisation of the Gallo-Roman city, thanks to models and the large bay windows overlooking the site. Don't miss the famous mosaic of the Ocean Gods, emblematic of the site, or that of the Punishment of Lycurgus.
