LUGDUNUM-Musée & théâtres romains, once known as the Gallo-Roman Museum, is a large archaeological site and museum. It is located in the area of the Roman theaters, on the slopes of the Fourvière hill, in the heart of the ancient Roman city of Lugdunum, founded in 43 BC and remembered for being the "Capital of the Gauls". The idea of a museum that would bring together objects related to the ancient Roman city of Lyon was born during the 1930s, but the project took shape only in the 1960s, and was then officially inaugurated in 1975. Almost invisible from the outside. , the museum blends into the landscape of an archaeological site consisting of a theater and an Odéon, which have become part of the UNESCO World Heritage Site. The architecture of the museum is voluntarily very sober, to highlight the works. Inside, the museum consists of a concrete ramp that descends in a spiral, branching off towards landings destined for the museum's collection. The latter collects discoveries that took place in Lyon and in the region. There are statues, jewels, everyday objects. But there are also Celtic artifacts from prior to the Roman occupation, such as a Celtic calendar, one of the longest Celtic documents ever discovered. A large model shows Lugdunum according to archaeological knowledge of 1975. Particularly noteworthy are a mosaic, discovered in 1806, offers a rare representation of chariot races such as those that took place at the hippodrome, and the "Tavola Claudia", discovered in 1528 , which reproduces in bronze the speech given in Rome by the emperor Claudius, born in Lyon, in 48 AD, in favor of the Gauls.
