The archaeological remains on this wooden hill at ‘Les Bouschauds” belongs to an ancient small town set very near to a roman road established by Agrippa. It passed lower down, further to the south and linked Lyon, the capital of the Gauls, with the Atlantic ocean.
The name of this locality is not known for certain, but many scholars believe the ruins here are to be those of Sermanicomagus, a staging post which appears on the Peutinger Table (a medieval copy of the network of ancient roads) but other sites can also lay claim to such identification (Luxe-La Terne) Ideally located at the confines of the territories of three “peoples”, the great double sanctuary received numerous visits. The dimensions of the adjoining theatre seem to confirm it popularity. In addition to the monuments that you will find higher up the hill, there is also an area of dwellings which covered an area of over 15 hectares.
Many rooms have been identified, including some which were heated by hypocaust, a large basin and several walls. An aqueduct proovided the water supply for this ancient village. The theatre at Les Bouchauds is one of the largest in Gaul (Diameter 105.60m) It could hold almost 7,000 people the the height of its splendour in the 1st century AD. It was built on the side of the hill to save on building materials. The tiered seats of the theatre were made of wood, they were installed for the season. In the lower part, some stone tiered seats were added towards the end of the 2nd century.
