Analisi territoriali in un’area della Sardegna centromeridionale: modelli ubicativi durante l’età del Bronzo

Abstract

The territory of Sarcidano is very important for the study of the settlements of the Nuragic population in the central-southern Sardinia (Italy), as the archaeological evidence of the late phases of Bronze Age and Early Iron Age shows. In particular, the great sanctuary of Santa Vittoria at Serri stands out on the homonymous plateau and exercises a control of the surrounding territory, corresponding in whole or part to the territories of the Serri, Escolca, Gergei, Isili, and Nurri municipalities. In this work, we experimented with an analytical procedure not yet widely used in the study of settlement processes in the Bronze and Iron Ages: that of Spatial Autocorrelation Techniques. The advantage of this approach lies in the fact that it not only shows spatial relationships, but does so on the basis of different values connected to the spatial data. Results showed that the Nuragic monuments were built near routes of passage so as to control the valleys below the basalt plains. This demonstrates the existence of a specific and organized approach for exploiting and monitoring the landscape, in which settlement choices depend on functionality criteria, with both nuraghi and villages having a key role on the strategic control of the territory.
