XVth century

After the peak of the 13th century, the priory had to go through major construction due to the constant flooding of the Loire. Thus, during the 14th century, a house - where Ronsard will live during the 16th century - was built for the prior.

Shortly after, traces of a large monetary donation given by Agnès Sorel to the community were found while the church's reconstruction was apparently financed by Louis XI, a neighbour of the priory through his favourite holiday spot: the Château of Plessis-lès-Tours.

At the same time, sculptures of Saints Cosme and Damien were placed in the main chapel that was dedicated to the twin healers.
