Tharros sits on the tip of the Sinis Peninsula, 20 kilometres west of Oristano, on a narrow strip of land between the sea and the Stagno di Cabras lagoon. The ruins occupy one of Sardinia's most dramatic settings: Phoenician, Punic, and Roman remains spread across a headland with sea views in three directions and the islands of San Pietro and Sant'Antioco visible on clear days.
The site is extensive — streets, baths, temples, a Punic tophet (sanctuary), and a Roman sewage system still intact — and only partially excavated. The best finds are in the Antiquarium Arborense in Oristano. Visiting Tharros in combination with the museum gives you the full picture. Mornings are best: the light is good and the tour buses haven't yet arrived.
