XVIth century

Ransacked by the Huguenots in 1563, the priory saw its defences strengthened under the Priorats of Charles de Ronsard and his brother, Pierre de Ronsard, who became commendatory abbot in March 1565.

It is here that the poet received visits from Charles IX, Catherine de Medici and the future Henri III. Saint Cosme was both a distant refuge from the corruption of the court allowing him to write and giving him great recognition.

Pierre de Ronsard remained at the head of his benefice until his death in December 1585. He was buried inside the church.
