It is to Guy de Noyers, Archbishop of Sens (1176 to 1194), that we owe the foundation of the Collegiate Church.
At the end of the twelfth century, during the reign of Philip Augustus, Guy de Noyers instituted a chapter of twelve canons in the church.
This first church was replaced in the thirteenth by a new one, around 1235, magnificent by its remains, because burned down during the hundred-year war, long before 1367.
Under the reign of Louis XII, the Tristan de Salazar Arch (1475 - 1519) undertook the restoration of the building.
From this renaissance period there are still 4 beautiful stained glass windows, including that of Saint Julien du Brioude.
Cardinal Louis de Bourbon, Archevèque de Sens (1536 to 1557) continued the restoration in order to completely erase the ruins of the war.
The restoration of the choir and vaults and the beginning of the transept are to be done.
The work was interrupted at the Cardinal’s death and the church remained unfinished, for only the Choir was in charge of the chapter. The commune and the parish were unable to finance the nave, which he had to maintain.
From this construction, we would build magnificent stained glass windows of the 13th and 16th century. and a Renaissance organ (1568) restored in 2011.
