On a basaltic plateau, on the border between the territories of Sarcidano and Trexenta, in the central-southern part of Sardinia, there is one of the most important and 'long-lived' of the island, from a federal Nuragic sanctuary to a Byzantine church. It is an evocative place where you will observe the evolution of the Nuragic civilisation in the Bronze Age up to the beginning of the Iron Age. Four groups of buildings are identifiable. The first is the sacred area, consisting of the well temple dedicated to the cult of water: it is the main building made with carefully crafted basalt blocks. Another architectural nucleus is the 'party enclosure', a socio-commercial area, for parties, business and the stay of 'foreigners'. A third group of buildings is made up of the huts and a fourth complex, where the 'execution enclosure' and the 'curia' with around 50 seats stand out: here, perhaps, the leaders of the various Nuragic peoples of the central Sardinia.

One of the most impressive, relevant and particular pre-Nuragic sites in Sardinia, it is located in the green countryside of Gerrei, in the central-eastern part of the south of the island. Extending over 200 thousand square metres and immersed in lush cork oaks and Mediterranean scrub of the Gerrei hills, it is one of the most evocative and important archaeological sites in internal Sardinia. To the north, in the locality of Su Crancu, there is the agglomeration of huts of reference to the necropolis. To the south of the village, there are the burial grounds of Pranu Muttedu and Nuraxeddu, exceptionally surrounded by large groups of menhirs, in pairs, in alignment or within the same tombs, and by round constructions of a probable sacral nature. Even further south, the domus de Janas necropolis of Genna Accas rises, dug into the rock, with three tomb circles.
