Site gallo-romain de Barzan, Archaeological museum and Roman settlement in Barzan, France.

The Site gallo-romain de Barzan, also called Le Fâ, covers 140 hectares on a plateau above the Gironde estuary. Its remains include a monumental Gallo-Roman temple, baths enlarged in the 2nd century, a theater, warehouses (horrea), and an aqueduct. A museum presents finds from excavations begun in 1994.

The Santones founded a sanctuary here around the 7th century BC, and by the 5th century BC imported Gallic and Hispanic pottery point to a trading post. Conquered by Rome in 58 BC, the town, likely Novioregum, flourished in the 2nd century AD with a theatre, baths and port. It declined by the late 3rd century and was quarried in the Middle Ages.

The museum displays everyday objects and crafts from Gallo-Roman times that reveal how people lived and worked in this settlement. These finds help visitors understand how trade and craftsmanship shaped daily life here.

The grounds are large and can be explored on foot, though some paths are unpaved and can become slippery in rain. It is best to wear sturdy shoes and bring a hat, as parts of the site are exposed to the sun.

A medieval mill building stands directly atop the foundations of a Roman temple, a visual reminder of how later generations reused the stones of older structures. This layering of different time periods remains visible today.
