Placed on a grandstand on the north side of the nave, the "Renaissance" organ of the Saint-Pierre church was built in 1568, making it one of the oldest organ buffets in France (with that of the Abbatiale de Saint-Savin, in the Hautes-Pyrénées). In 1695, the restoration of the Organ was entrusted to Julien TRIBUOT, organ builder of King Louis XV. Julien TRIBUOT dismantled all the games, as well as the 12 front pipes and added to the instrument a set of Trumpet and a Cornet of IV rows on a half-keyboard of Echo. Around 1770, works of 1,500 pounds were carried out by Factor Pierre CROCHU. The instrumental part of the organ has been classified as an object by the Historical Monuments since May 12, 1978. From 2003 to 2008, the company of Bertrand CATTIAUX de Liourdres (Corrèze) restored the instrument as it existed in 1737, in accordance with the Parish Archives stored at the Archdiocese of Sens. He was relocated to his gallery in 2011.
