Uthina was a Roman colony founded by veterans of Legio XIII Gemina — soldiers who survived Rome's wars, rewarded with land in Tunisia's wine valley. The Uthina Archaeological Site (~20 km west of Mornag, GPS: 36.6076, 10.1722, 8 TND entrance, Monday closed) has an amphitheater for 15,000 people and an extraordinary Bacchic floor mosaic: 28 Cupids harvesting grapes, young Dionysus seated calmly, a bearded slave presenting the first grape to King Ikarios. It's the founding myth of wine rendered in stone 2,000 years ago, in the same valley where Chateau Mornag grapes grow today. Enter through the main gate, head to the amphitheater first for scale, then find the villa ruins for the mosaic. If you've tasted at the winery, bring a bottle — drinking Chateau Mornag in view of ancient Romans celebrating the same grapes makes time feel thin.
🔄 BACKUP: If Uthina is closed or under maintenance, the nearby ruins of Thuburbo Majus (40 km southwest, GPS approx. 36.4200, 10.0700) offer comparable Roman wine culture and mosaics.
