The strait between Corsica and Sardinia was an important trade route in imperial times, particularly between present-day Spain and Rome. Researchers led by Nadine Mattielli and Sébastien Clerbois, teams from the CReA-Patrimoine (Faculty of Philosophy and Social Sciences) and the G-Time Laboratory (Faculty of Sciences) of the Université libre de Bruxelles (ULB) have now discovered that the various granite extraction sites on the island of Cavallo/San Bainzu (Lavezzi archipelago), Bonifacio, Corse-du-Sud), undoubtedly constitute one and the same quarry, with important dimensions, thus forming the largest quarry in Bonifacio.
The ULB project is part of a Collective Research Programme (PCR) directed by Gaël Brkojewitsch (Metz Métropole, associate researcher, Aix-Marseille University, CNRS, CCJ, Aix-en-Provence). The study and the archaeological surveys have been authorised by the Ministry of Culture and the Prefecture of South Corsica and are partly financed by the Regional Directorate of Cultural Affairs of Corsica; the research is placed under the scientific control of the Regional Curator of Archaeology in Corsica, Mr Laurent Sévègnes. In Belgium, the programme is supported by the Fédération Wallonie-Bruxelles, the FNRS and the Université libre de Bruxelles.
