Origin and history

The site of the Graufesenque, called Condatomagus in Roman times, was the largest sigillated ceramic workshop of the Roman Empire in the first century. Located 1 km west of Millau (Aveyron), on the left bank of the Tarn, it enjoyed a strategic position near the confluence with the Dourbie, at 370 m altitude. Its name, of Gaulish origin (condate, "confluent"), reflects its economic role related to trade and artisanal production. The Rutènes, a local Gallic people, already occupied the site, as evidenced by the protohistoric poppidum of the Granède, 1.5 km away.

The pottery workshops of the Graufesenque reached their peak between 40 and 60 AD, becoming the first center of production of sigillated ceramics in the Roman West. Their products, exported to Germany, Greece, Syria or Egypt, even replaced Italian workshops. The fine dishes, often stamped and covered with a brick-red varnish, were made from local clays (Domerian marnes) and triasic dengobes. Cooking at 1,050–1,060 °C allowed for massive production, as evidenced by an oven capable of cooking 40,000 vases in 3–4 days.

The decline began at the end of the first century, marked by the depletion of clay deposits and competition from other sites such as Lezoux (Auvergne). The workshops partly moved to Bannasiacum (now Banassac), where production continued until the second century. The Graufesenque finally ceased its activity around 120–150 AD, after a phase of qualitative decadence. The site also included a craft area, habitats, temples (including a Gallo-Roman fanum), and thermal baths, revealing a complex social organization including slaves and artisans.

The first archaeological discoveries date back to 1830, when an oven was discovered during a flood. The systematic excavations began in 1862 (Abbé Malzac), then continued with Abbé Ceres (1880–86), who emphasized the extent of the site and its commercial outreach. Canon Frédéric Hermet (1901–1906) published major works, confirmed by Joseph Déchelette, which identified marks from the Graufesenque to Pompeii. Modern research, carried out by Alain Vernhet from 1975 onwards, allowed the organization of workshops and their chronology to be reconstructed in six periods, from 10 to 150 AD.

The Millau Museum, inaugurated in 1980, now exhibits collections of sigillated ceramics (cuts, bowls, lagenes) and "borrowing sheets" engraved by potters. Archaeological remains, protected since 1951 (inscriptions and rankings at the Historic Monuments), include ovens, a hypocauste, and temples. The site illustrates Roman technical innovation, industrial standardization, and the key role of Gaulish artisans in the imperial economy. The graffites found, published by Robert Marichal (1988), also offer a unique insight into daily life and work organisation.
