The sequencing of these concretions, although not very thick, allows us to retrace parts of the history of the aqueducts. For the aqueduct of Villenoy, the petrographic study confirms the chronological succession of two major phases and two types of operating modes. In the case of the aqueduct of Reims, it forces us to question the very short time recorded in the preserved concretions.}}
