History
Châtillon-sur-Chalaronne Castle is a medieval motte castle in France, established around the beginning of the eleventh century by the lords of Châtillon. A motte castle used an artificial or naturally adapted earthen mound with a fortified enclosure. The site became the centre of the Châtillon lordship, the fortified residence and administrative base of its ruling lord, and of the Bresse district administered from Châtillon-les-Dombes.
Origins of the lordship
At the beginning of the eleventh century, the castle belonged to Hugues de Châtillon. By 1070 it had its own lords, who were also associated with Montrevel. In the late eleventh or early twelfth century, the lordship passed to Humbert II of Beaujeu, although the circumstances of the transfer are uncertain.
In 1212, Guy, the fourth lord of Châtillon-les-Dombes, held the castle together with rights and possessions in Saint-Didier-d’Aussiat, Saint-Martin-le-Châtel, and Chaveyriat. In January 1228, the lordship passed through marriage to Renaud, lord of Bâgé, who married Sibylle, daughter of Guichard IV of Beaujeu. Renaud ceded it in 1272 to Philip I, Count of Savoy and Burgundy. After Philip’s death, the castle passed to his nephew Amadeus V of Savoy, and the successors of Amadeus retained it until 1535.
Savoyard stronghold
The castle served the counts of Savoy as a defensive position for Châtillon-sur-Chalaronne and as a substantial residence capable of accommodating receptions. Its buildings therefore had both military and representative functions. In 1409, Amadeus VIII of Savoy received the homage of Philip of Bourbon, Count of Clermont, at the castle. In 1410, Amadeus VIII had the statutes of the Order of the Annunciation drawn up there. This chivalric order had been founded by his grandfather, Amadeus VI of Savoy.
The castle was built or rebuilt through several medieval phases, with major alterations in the fifteenth century. Its strategic role ended during the seventeenth century, although ownership and use of the ruins continued through later changes of control.
French conquest and later ownership
In 1535, Francis I conquered Châtillon and Bresse. Henry II transferred the castle in 1555 to Étienne de la Forge, lord of Chaillouvres, but returned it in 1559 to Emmanuel Philibert, Duke of Savoy. On 26 June 1561, Emmanuel Philibert made Châtillon a county and exchanged it with Jean-Louis de Costa for the County of Benne in Piedmont.
After Jean-Louis de Costa died on 11 June 1564, the county passed to Christophe d’Urfé. His heirs sold it in 1615 to François de Bonne de Lesdiguières, Marshal of France. Lesdiguières’ daughter, Françoise de Bonne, Duchess of Créquy, sold it on 7 December 1645 for 47,000 livres to Gaston d’Orléans, the father of Mademoiselle de Montpensier. Gaston incorporated Châtillon into his family’s inherited possessions.
Destruction and preservation
The castle was destroyed in 1600 during the conflict between France and Savoy, after Henry IV declared war on the Duchy of Savoy and Bresse was invaded. The enceinte, or fortified outer wall, the entrance gateway, and the foundations of four of the original seven towers survived the destruction.
In 1715, Philippe d’Orléans gave the upper part of the ruins to the Ursuline nuns, members of a Catholic religious order especially associated with the education of girls. From 1757 to 1776, the remains were held by Camille-Louis Perrichon, lord of Tremblay. A later rehabilitation campaign raised four towers and secured the site. The ruins are owned by the Commune of Châtillon-sur-Chalaronne and have been protected as a French historic monument since 1927.
The chapel within the enclosure
A chapel dedicated to the Virgin Mary stood inside the castle enclosure by the beginning of the twelfth century. Around 1110, Archbishop Gauceran gave it to Ainay Abbey, a major Benedictine abbey in Lyon. The grant was confirmed around 1124, on 5 March 1135, on 26 February 1153 by Pope Eugene III, and in 1250 by Pope Innocent IV. The chapel still existed at the end of the fourteenth century, when Henri de Chalamon served as its chaplain in 1363.
Remains
The castle occupied a naturally elevated promontory, known locally as a poype, on a slope beside the Chalaronne and above the town to the south. Its surviving layout belongs to a fortified motte complex with a polygonal enclosure defended by projecting towers. Brick and wood were used in its construction, while the surviving flanking towers are built of brick.
Layout and surviving structures
Fortified enclosure
The castle’s enceinte formed a polygonal boundary around the elevated site and was flanked by seven towers in its original arrangement. Only sections of the wall and other fragments remain from the enclosure after the destruction of 1600. The foundations of four towers survived, and four towers were later raised during the rehabilitation campaign, giving the ruined site a partially reconstructed defensive outline.
Entrance gateway
The surviving entrance gateway has an ogival arch, a pointed arch form. It stands among the remaining wall sections as one of the clearest preserved elements of the castle’s access system. The gateway and the surviving brick tower structures belong to the defensive fabric that continued to mark the site after the main castle was destroyed.
Chapel of the Virgin Mary
The former chapel of the Virgin Mary stood within the castle enclosure. Its presence reflects the religious use of the fortified residence, alongside its administrative and defensive functions. The chapel’s medieval history continued into the fourteenth century, when it had its own chaplain.
