International audience. This research program, involving French and Italian institutions, aims at understanding how the settling and development of the Etruscan city of Orbetello affected the environmental evolution of its lagoon, and how the evolution of the lagoon affected in turn the economics of Orbetello. In other words, to define how the life of the city has been influenced by its own impact on the lagoon. To achieve this we have followed two lines of research. One is historical, based on the analysis of iconographic, textual and archaeological archives from antiquity to the present day. The other, paleoenvironmental, is based on the analysis of sedimentary archives. The idea is to combine several investigation methods to map the dynamics of sedimentation, by means of geophysical prospecting (imaging of the sedimentary architecture using acoustic profiles) and the study of sedimentary cores. The latter allow the dating of sediments, the analysis of their biological components to reconstitute lagoon palaeoenvironments (ostracods, pollen, dinoflagellate cysts, malacofauna, composition of organic matter), and the analysis of metallic contaminants, highlighting the changes induced by lagoon management and the development of the city.
