History
Château des Montils is a small fortified castle in France, built in the historic County of Blois to protect the Blésois from hostile neighboring powers and military incursions. Its foundation is traditionally attributed to Thibaud I of Blois in the mid-tenth century, although the castle appears with certainty in twelfth-century charters. Construction is generally placed around 1140 or about 1144, during the medieval period, and is associated with Thibault IV, also known as Thibault of Champagne.
Foundation and the counts of Blois
Thibault IV is said to have enclosed an existing country residence, or villa, to protect it from attacks by Sulpice of Chaumont. The fortified place subsequently appeared in charters under the name Castrum de Monticiis. The residence of the counts of Blois within the enclosure was probably enlarged toward the end of the twelfth century. The counts visited frequently, encouraged by the castle’s strategic position and by the extensive forests around it, which provided hunting grounds.
Gauthier of Avesnes and Marguerite, counts of Blois, acquired the town in 1218 from Elisabeth of Amboise. They established a chapel there in 1222, while Jean I of Châtillon granted the inhabitants a charter of privileges in 1246. Such a charter was a formal grant that defined rights or exemptions for a town and its residents. In 1295, Hugues II of Châtillon reattached the Montils to the County of Blois for administrative and financial purposes.
Religious foundations and noble patronage
Alix of Brittany, the wife of Jean I of Châtillon, became closely associated with the site through her charitable patronage. She founded and endowed a Maison-Dieu near her residence. A Maison-Dieu was a medieval charitable or religious institution commonly connected with care for the poor, the sick, or travelers. After Alix died in the Holy Land in 1288, her heart was placed according to her wishes in the chapel of the Montils Maison-Dieu.
Jeanne of Châtillon, the wife of Pierre of France, also supported the Maison-Dieu from her own fortune. Tradition relates that Louis IX, known as Saint Louis, visited the Montils to see his daughter-in-law. The castle’s royal connections continued in the following century. Philip IV stayed there on 9 August 1301, and the Blessed Charles of Blois spent his childhood at the Montils.
Fortress during war and restoration
The fortress gained importance during the prolonged conflicts between the houses of Champagne and Anjou. By the fourteenth century, it formed one of the four fortresses guarding the County of Blois. The castle was reportedly destroyed or dismantled in 1356 during the devastation of Sologne and the southern Blésois associated with Edward the Black Prince, the English military leader and eldest son of Edward III. The attribution remains disputed. The English movement through the region was brief, and the defenders may instead have dismantled the fortifications because they could not, or would not, continue to hold them.
Gui de Châtillon restored the castle tower during the fourteenth century. Documents concerning works at Blois suggest that the enclosed settlement contained about twelve houses within its walls. The Montils therefore combined a defensive stronghold with a small residential community and the counts’ residence.
Orléans rule and royal visits
Louis of Orléans took possession of the castle in 1392 after acquiring the bare ownership of the Blésois. His son, Charles of Orléans, lived intermittently at the Montils between 1411 and 1465. Despite the financial pressures placed on French towns during the Hundred Years’ War, the Montils remained prosperous under his protection.
Mary of Cleves, Charles of Orléans’s wife, added four rooms with fireplaces to the castle in 1467. Her painter, Pierre André, produced a large altar table for the chapel in 1472. Louis XI stayed at the Montils in 1463. In 1489, Joan of France received the castle through letters patent and undertook major renovations in preparation for a visit by Charles VIII. The king never arrived because he died at Amboise shortly before the planned journey.
Louis XII stayed at the castle in April 1499 and again in 1505, when Anne of Brittany treated him during an illness. Their daughter Claude of France also stayed at the Montils. In 1519, Claude authorized the conversion of a wheel at Rouillon Mill, near the castle, from fulling cloth to milling grain.
Decline and abandonment
The castle’s decline accelerated as the French court favored more comfortable residences. During the Wars of Religion, the sixteenth-century conflicts between Catholics and Protestants in France, the Huguenots destroyed the town. Huguenots were French Protestants associated chiefly with the Reformed tradition. The walls of the town and castle suffered further encroachment and demolition, recorded in 1614.
The castle was finally abandoned under Louis XIV. Two contractors from Blois completed its demolition by about 1679, and in 1682 the site was described as ruined. Charles de la Vallée, recorded in 1663 as a squire and lord of Terrouenne and the Montils, acquired the Montils and its dependencies from the Crown through a royal auction held at the Louvre on 17 June 1697. After that transaction, the castle was no longer part of the royal domain. Château des Montils was listed as a French historic monument in 1986 and survives as a ruin.
Remains
The fortress occupied the summit or steep southern slope of a hill. The Beuvron flowed at the foot of the hill and helped protect the approaches, while steep ground, the bends of a bridge, and Rouillon Mill formed part of the surrounding defensive landscape. The surviving complex includes a large tower, parts of a triple enclosing wall, outer fortifications, a cylindrical keep, and a monumental gate that once announced the residence of the local lords.
Defensive structures
Main tower and keep
The main tower was built in the twelfth century, although it has also been described more broadly as an eleventh- or twelfth-century monument. It stood between two deep ditches. Its upper crenellated crown was lost through successive mutilations, and much of its masonry has disappeared. The cylindrical keep measures approximately 16 metres in diameter and forms the principal surviving element of the fortress.
Subterranean works and water supply
Subterranean passages or excavations existed beneath the tower. Tradition assigned them a strategic purpose, but they were interpreted as domestic features rather than oubliettes. A very deep well was dug at the center of the tower. Water was drawn from the first floor through a cylindrical, column-shaped conduit that was still described as existing in an early twentieth-century account. The ground floor served the garrison and provided space for provisions and military engines.
Enclosing walls and monumental gate
The fortified enclosure contained the counts’ residence and approximately twelve houses. Fragments of a triple enceinte, meaning a defensive wall system arranged in three circuits, survive with portions of the outer fortifications. The monumental gate formed the formal entrance to the seigneurial residence. By the early twentieth century, the large tower, sections of the three defensive circuits, the outer works, and the gate remained as ruined structures.
Residential and religious buildings
Residence of the counts
The counts of Blois maintained a residence inside the fortified enclosure. It was probably expanded toward the end of the twelfth century, and Mary of Cleves added four rooms with fireplaces in 1467. These works formed part of the castle’s continued use as a noble residence during the later medieval period.
Chapel and Maison-Dieu
A chapel was established within the Montils complex in 1222. Near the residence stood the Maison-Dieu founded by Alix of Brittany, together with its associated chapel. That chapel received Alix’s heart after her death in 1288. It also contained a large altar table made by Pierre André in 1472, linking the surviving historical record of the religious complex with the artistic patronage of the late fifteenth century.
Rouillon Mill
Rouillon Mill stood near the Montils and included a wheel originally used for fulling cloth. In 1519, Claude of France authorized its conversion into a grain-milling wheel. The installation forms part of the documented economic landscape around the castle and reflects a change in the use of one of its nearby water-powered facilities.
