La Graufesenque
Millau, France
La Graufesenque is an archaeological site 2 km from Millau, Aveyron, France, at the confluence of the rivers Tarn and Dourbie. As Condatomagus (market of the confluent), it was famous in the Gallo-Roman period for the production of high quality dark red terra sigillata Roman pottery, which was made in vast quantities and exported over much of the western part of the Roman Empire. The site, partly owned by the commune and partly private, has been listed by the French Ministry of Culture since 1926. It was classified as a monument historique in 1995.
