Near Oristano you can visit the famous site of Tharros, a Phoenician-Roman port city that was abandoned in the year 1000 AD. Unfortunately not a lot is left of what it once was. A bit disappointing collection of rubble. The two pillars that are standing are clearly new and could be of the Roman Film Studios. Much better is it to visit the Archeological Museum in Oristano where all the interesting artefacts of Tharros are kept.
