The town, founded by the Phoenicians in around 750 BC. It is reached along a road that runs along a narrow strip of land almost 3 km in length. Built by the Carthaginians and completed by the Romans, it joins Sant'Antioco to the main island. To the right of the road, just before the new bridge, you will see the ruins of the arched Roman bridge marking the original route.
Town life is centred around Corso Vittorio Emanuele, Via Roma, Piazza Umberto, Piazza Italia and the promenade, which leads to the archaeological area comprising the museums, the Savoy fort, the Punic necropolis and the Phoenician tophet. The Ferruccio Barreca archaeological museum tells the Phoenician, Punic and Roman history of Sant'Antioco, one of the largest ancient settlements on the island of Sardinia.
To fully understand the local history and culture, visit the hypogeum village and the ethnographic museum, where you can also learn about sea silk. Byssus is a precious fabric: silk that comes from the sea.
