Château de Monthoux
The Château de Monthoux is a former fortified castle built in the mid-13th century. It is located in the commune of Vétraz-Monthoux, in the department of Haute-Savoie, within the Auvergne–Rhône-Alpes region. From the 13th to the 15th century, it served as the seat of a châtellenie.
Location
The castle was constructed on a hill at the entrance to the Arve Valley, overlooking Annemasse and positioned between the to the northeast and the Petit Salève to the southwest. It occupies the northern end of the hill, oriented toward the northeast, in an area known as Haut Monthoux. Located at an elevation of 567 metres, it overlooked the Arve below and controlled the roads linking Annemasse to Bonne and to Bonneville.Opposite the site stands the, which controlled the opposite bank of the valley and belonged to the.
According to historian, in his thesis Les enquêtes de 1339 en Dauphiné et en Faucigny, intérêt démographique, the castle was situated about one league from Geneva, with a vantage point from which the entire city was visible, making it difficult to leave Geneva without being seen from the castle.
The castle’s chapel belonged to the bishopric of Geneva, which became a source of tension between the Baron of Faucigny and the bishop.
History
The Swiss archaeologist Louis Blondel suggests that the hill may have hosted an earlier fortification. The site was developed “shortly before 1245” by Aymon II, Baron of Faucigny, who established the town and the Château de Monthoux on the border with the County of Geneva, alongside other new settlements such as the villeneuves and the. Each of these settlements was accompanied by a castle. Pope Innocent IV authorized the creation of a chapel within the Château de Monthoux. The estate belonged to the Faucigny family, first to Aymon II, then to his daughter Agnès, who married Peter of Savoy. It later passed to their daughter Beatrice, known as the “Great Dauphine,” who married Guigues VII, Dauphin of Viennois.Dauphine Béatrice pledged the castle in 1269 while she was held captive by her aunt, and in 1270 it passed in pledge to her uncle, Count Philip I. In May 1293, Béatrice of Faucigny transferred the property to her cousin, Count Amadeus V of Savoy. The following month, the Great Dauphine performed homage to the Count of Savoy for the castle.
The construction of the in 1304 was challenged by Hugues, lord of Faucigny and son of the Dauphin of Viennois, Humbert I, who claimed that the structure had been built on his lands. The Count of Geneva disputed this claim, as the new castle posed an issue for the Château de Monthoux, which controlled the northern entrance to Faucigny. An agreement was reached during a meeting at the on 13 October 1304. The two lords stipulated that the castles of Monthoux and Gaillard owed each other mutual protection and would provide support in the event of an attack by the Count of Savoy.
During the peace treaty concluded in August 1308 between the Count of Savoy and the Great Dauphine Beatrice, the castles of Faucigny, Bonne, Monthoux, Bonneville, Châtelet-de-Crédoz,, and Lullin, along with their mandements and jurisdictions, were included in the agreement.
On 22 April 1532, Michel sold the castle and its mandement to Michel Guillet for 1,400 gold écus, plus 600 gold écus for redemption rights and the rights to redeem the tithes near Collonges. The new owners subsequently adopted the name Guillet de Monthoux.
Description
The castrum comprised a keep with its enclosing wall, a village situated below, and a church, all contained within a fortified perimeter.According to Louis Blondel, the Retable of Saint Peter by Konrad Witz includes a landscape featuring the castle. The depiction shows a substantial keep, estimated at 29 × 29 metres, surmounted by a taller tower.
Châtellenie of Monthoux
The Château de Monthoux served as the center of a châtellenie, or mandement, within the seigneury of Faucigny. During the Delphinal period, Faucigny was organized into fifteen châtellenies, one of which was Monthoux.In the 14th century, the châtellenie encompassed the parishes of Haut- and Bas-Monthoux, Annemasse, Ambilly, Sales, and Vétraz.
