The Gallo-Roman Museum of Lyon is a museum on the Gallo-Roman civilisation in Lyon (Roman Lugdunum), previously located in the heart of the Roman city and now sited near the city's Roman theatre on the Fourvière hill, half-buried into the hillside on the edge of the archaeological site. The new building was designed by Bernard Zehrfuss and opened in 1975. Internally, it is formed of a concrete spiral ramp descending and branching out into the display rooms. It is managed and operated by the Rhone department jointly with the archaeological museum of Saint-Romain-en-Gal. As well as displaying its own permanent collections of Roman, Celtic and pre-Roman material (inscriptions, statues, jewellery, everyday objects), a plan-relief of the ancient town and scale models of its major monuments such as the theatre and the Odeon, it also regularly hosts temporary exhibitions.
