Nuraghe Arrubiu stands on the Pranemuru plateau, in the Sarcidano, an area inhabited since prehistoric times. Complex nuraghi, towers, villages, giants' tombs and places of worship testify to a densely inhabited region crossed by a dense network of economic, cultural and religious exchanges.

The Nuragic sanctuary of Santa Vittoria is the main cult and ceremonial place of the Sarcidano, in central-southern Sardinia. It stands on the plateau, called Giara in Sardinia, of Serri, inhabited since prehistory. From a position dominating much of the Sarcidano, the sanctuary is directly connected with numerous nuraghi, villages and burial areas. It includes several groups of buildings, among them the well temple, a peculiar circular structure known for the precise shaping of its stone blocks.

The Pranu Muttedu archaeological area stands on a wide plateau overlooking the valleys in the heart of the Gerrei. The necropolis is one of the most important funerary complexes of Sardinian prehistory: megalithic tombs, circular structures for funerary cults and fifty menhirs, the largest group of megalithic blocks found in Sardinia, arranged in different patterns with proto-anthropomorphic shapes. Among them stands out Tomb II.
