The first traces of settlement in the territory of Villasor, a town in the region Campidano di Cagliari, date back to the Nuragic age.
The most relevant of these testimonies is the complex called Su Sonadori, in the locality of S’Acqua Cotta, about 12 kilometers from the town, in the direction of Villacidro. It consists of a central tower with a diameter of 10 meters, surrounded by a bastion made up of six independent towers, different in shape and size, connected by curtain walls. Around the complex, the remains of the village are clearly visible, consisting of circular huts. The site can be classified between the Middle Bronze Age and the Late Bronze Age.
Other well-preserved nuraghi are those of Monte Zippiri and Monte Zippireddu and those of Carronca Simoi.
A giants’ tomb in a poor state of conservation was also found in Gutturu Longu valley floor.
One of the most important sites from a scientific point of view is the hoard of Su Scusorgiu, from which forty swords come, perhaps originally collected inside a jar, tied with a metal band. These objects were intended to be fixed, by means of a lead casting, in very visible positions above the temple structures, as a distinctive sign of veneration for the frequenters of the site. The chronology of this hoard is uncertain: a dating in the Late Bronze Age is the most likely.
The territory was later exploited for cereal cultivation in the Punic and in the Roman era.
Other evidence of the past concerns the remains of a bridge in the Ponti Perda area and a small settlement near the thermal spring of S’Acqua Cotta.
