Lugdunum Convenarum, Roman city in France
Lugdunum Convenarum is the remains of a Roman town in present-day Saint-Bertrand-de-Comminges in France and shows the traces of a settlement that served as a key regional center. On the ground you can see sections of old streets, walls, a bath complex, a theater, and building foundations that reveal how the ancient city was laid out.
The city was founded in the first century under Emperor Augustus and grew into a busy trading center with a forum, temples, and public baths. In the fifth century a protective wall was built around the upper part, and later in the Middle Ages a new center formed around a cathedral built by Saint Bertrand.
The site's name derives from the Celtic god Lug and the Convènes people, reflecting a place where Celtic and Roman cultures met. Visitors can see how Roman ways blended with local traditions through the remains of temples, markets, and public buildings.
The site is not heavily developed and has no large visitor centers, but signs mark important parts of the ruins and information boards explain what remains. A self-guided walk at your own pace works best to explore the scattered structures and learn about how the ancient city was arranged.
A large market building called the macellum was excavated here and was the largest known market building in the western Roman Empire, underscoring the trading importance of this place. Visitors often overlook this notable commercial function that went beyond typical administrative and religious roles.
