The RomanCe project concerns the study of the Romanisation processes in the Centre-Val de Loire region (France) during Antiquity (2nd century BC - 5th century AD). It is based on the study of territories, urban and rural landscapes, and the evolution of the social, economic and political structures of the populations of the late Iron Age and the Roman period. Thanks to their archaeological wealth, several emblematic sites in the region, in Berry, Touraine and Beauce, make it possible to address this issue. The recent archaeological excavations carried out at Châteaumeillant (18), Amboise (37), Batilly-en-Gatinais (45) and Manchecourt (45) initiated in 2019 have made it possible to collect an abundant and remarkable set of data, even exceptional in the case of Chateaumeillant and Amboise, which are perfectly integrated into the major current issues at the regional, national and international European levels.
