Tharros - Capo San Marco in the Phoenician and Punic Age. Geophysical investigations and virtual rebuilding

The project described in this paper was started in 2012 and concerns the study of the relationship between the urban and suburban districts of the Phoenician and Punic city of Tharros (Cabras, Oristano). The structures of Phoenician and Punic Tharros have been largely cancelled by the Roman occupation. For this reason it is very difficult to determine the original function of many of the neighbourhoods during the Carthaginian period. The archaeological excavation primarily involved the southern necropolis of Capo San Marco. The cemetery must still be fully explored and understood under several aspects, mainly because of the devastation of the site caused by the repeated plundering of the ancient tombs which occurred during the 19th century. In addition to the new dig activities, a 3D topographical survey aimed at the complete documentation of the site and at the virtual rebuilding of the Phoenician and Punic funerary landscape was completed. Another goal of the project is the insertion of this sector of the promontory into the usual tourist route, in order to foster the public fruition of Capo San Marco, while continuing to adopt proper scientific methods and modern techniques. In this direction, geophysical prospecting surveys were carried out in the southern sector of the Capo San Marco, near the so-called ‘Rustic Temple’, in order to assess human presence in the farthest point of the Sinis peninsula (characterised by the presence of the Late Punic ruins of a probable light-house with sacred functions), and across the whole isthmus Sa Codriola towards the hill of San Giovanni, with the aim of analysing the northern boundary of the cemetery and its relationship to the city. The Punic-Roman settlement is now enclosed in the archaeological park, which is a fraction of what was supposed to be the administrative capital of Carthage in Sardinia. 3D modelling and virtual reconstructions were focused also on the residential Punic and Roman area inside the park. The integrated application of the most advanced topographical and geophysical techniques to the site greatly contributed to the recording and understanding of the ancient landscape.
