The museum was inaugurated in 1997 and is dedicated to the exhibition of archaeological finds from the territory of the Sinis peninsula. The prenuragic and nuragic period is documented by the materials recovered with the excavation of the village of Cuccuru is Arrius which has given significant evidence from the Middle Neolithic period.
The historical age is instead well represented by finds from the ancient city of Tharros, built by the Phoenicians on a pre-existing nuragic village and expanded in an urban style in the Punic and then Roman times. The Phoenician-Punic materials exposed come from the excavation of the city's craft district and from the tofet to which the urns and steles on display are shown.
