Before the 13th century there were two parishes, Saint-Sauveur and Saint-Gilles, in 1300 the bishop of Chartres united them into one by a charter of Berchères, because of the smallness of the two parishes. The church dates from the beginning of the 17th century. Rebuilt on the foundations of an old Romanesque church, its originality comes from its bell tower with saddle roof, its caquetoire and its paneled vault redone in 2003. At the initiative of the Prince Duke of Montmorency-Laval, it has contained the reliquary of Sainte-Félicité since 1838. Saint Félicité, whose relics are in Montigny-le-Gannelon, is a martyr whose life is unknown, whose body was taken from the sacred cemeteries of Rome. We have his body, the skull, the bones of his arms, fingers and feet. They were removed from the Saint-Cyriaque cemetery in 1828 and placed in their respective places on a body artistically modeled in wax and measuring more than 1.40 meters in length. A magnificent chase, of the shape and size of an altar tomb, all furnished with glazing and embellished with gilding received this precious deposit. Pope Leo XII donated it to the Duke of Laval, then Charles X's ambassador to Rome. On his death, he bequeathed it by will to the church of Montigny-le-Gannelon where the old historic castle of Laval-Montmorency is located. The venerated hunt is now placed under the main altar of which it forms the tomb.

Almost nothing is reliably known about the life of Saint George (Saint-GEORGES), to whom the church of Cloyes-sur-le-Loir was dedicated, but the veneration of his person goes back to early Christianity. A martyr identified with George is said to have lived in the third century. However, the legend of St. George as a dragon slayer is well known and widespread; he is usually depicted - in paintings or as a statue - as the conqueror of the monster, often as a knight on horseback. The memorial day of the very popular George - he is, among other things, patron of the English kingdom - in the calendar of saints is April 23rd.

The church of Saint-Sauveur-Saint-Gilles and the castle of Montigny-le-Gannelon Montigny-le-Gannelon are wonderful. You just have to go over the mountain. Montigny-le-Gannelon Castle dates from the Renaissance period; it was redesigned during the course of a restoration in the 19th century Neo-Gothic.
