Avenio, Archaeological site in southern France.

Avenio is an archaeological site in southern France containing multiple structures such as ancient bathhouses and temples. These buildings demonstrate Roman construction methods and architectural techniques.

Excavations at Avenio have uncovered numerous artifacts and structural remains from Roman settlement in southern France. These discoveries date from a period of intensive development and economic activity in the region.

The name Avenio comes from a pre-Latin root *ab-ēn plus a Gallic-Latin suffix -(i)onem, linked to the waters of the Rhône and the Durance, the river once feared for its floods. Coins struck here imitated those of Massalia, showing a head of Apollo on one side and a wheel or boar above the letters A. O. Y. E., short for Aouenion, on the other.

Access to the excavation site is through organized visits with guided tours that explain the findings. It is advisable to wear sturdy footwear and be prepared for partially unpaved areas.

The location lay at the intersection of ancient trade routes and was therefore an important commerce point in Roman Gaul. The artifacts suggest active exchange relationships with distant regions.
