The presence of a hundred, more or less certain or hypothetical, ancient sanctuaries has been highlighted in Bituriges Cubi’s territory. A corpus of religious sculptures and epigraphy has been collected too. These data shed light on the religious landscape of the biturige territory. This article examines the main religious dynamics (permanence, mutation, adoption), between the middle of the second century B.C. and the middle of the first century A.D. We then assess the place of these processes in the evolution of the organisation of the society and its territory.
