Château de Charousse

The Château de Charousse (Charosse), also known as Pierre Brûlée (castro de Charossa), was a medieval castle dating from the 11th century, now entirely disappeared. It was situated in the County of Geneva but constituted an enclave within Faucigny. The site was located above the commune of Passy in the department of Haute-Savoie, in the Auvergne-Rhône-Alpes region.

The castle was constructed on a buttress of the Aiguille de Varens, on the right bank of the Arve, at an altitude of about 1,000 meters.^[1][2] Positioned above the village of Passy, it commanded the upper Arve valley between Sallanches and the defile leading to the Chamonix valley, as well as the routes toward the Col de Megève and the Val d’Arly, and the Val Montjoie.^[1][2]

Access to the site was possible only from the eastern side. Owing to its position overlooking the mountain, the castle is often described as an “eagle’s nest.”^[2]

The castle served as the center of a mandement on the right bank of the Arve. To the north, it bordered the lands of the Priory of Chamonix, with the Diosaz torrent marking the boundary between the two fiefs.^[3]

Canon Gros' records mentions of Charousse beginning in the 13th century. The earliest reference appears in a 1225 document naming a Guillaume de Cherrossa, according to the Régeste genevois.^{[ReG 1][4]} Variants of the name appear as Charossa in 1250 and 1268 (cited by Samuel Guichenon), Carossia in 1296, and Charosia in 1485.^[4][5]

The origin of the toponym is interpreted in several ways. Louis Blondel derives “Charousse” from charoutze, meaning “burnt rock.”^[1] Canon Adolphe Gros proposes a derivation from calma russea, meaning “red pasture.” Henri Suter’s interpretation, paralleling that of “Chamrousse,”^[4] links the name to a mountain pasture, formed from Cha (from the Gaulish calmis) combined with the adjective rousse.^[5]

Swiss archaeologist Louis Blondel dates the oldest identifiable remains of the site, particularly those of the tower, to the late 12th or early 13th century.^[6] He also considers that the earliest structures may be older, possibly originating in the 11th century.^[7]

The name Charousse is first recorded in 1225^{[ReG 1]} in a transaction at Thônex involving Count William II of Geneva and Aymon II of Faucigny as part of a conflict settlement.^{[3][ReG 1]} The castle is attested in 1250 according to the Régeste genevois.^{[3][ReG 1]} It functioned as the center of a châtellenie.^[6][2] The lords of the mandement were vassals of the County of Geneva, making the territory an enclave within Faucigny, although certain seigneurial rights appear to have been held by the Counts of Savoy. Historians attribute this situation to the marriage of Thomas I of Savoy and Margaret of Geneva around 1196.^[3] The Counts of Geneva regularly rendered homage to the Counts of Savoy for the fief.^{[ReG 2][ReG 3][ReG 4][ReG 5][ReG 6]}

The status of the seigneury became more complex with the expansion of Savoyard influence in the valley. In the late first half of the 13th century, the Counts of Savoy established alliances with the lords of Faucigny.^[8] Peter II of Savoy married Agnès of Faucigny, heiress of the House of Faucigny, in 1234. In 1249 or 1250, Count Peter II of Savoy seized the castle of Charousse from Count William II of Geneva.^[8] In 1259, Pierre of Savoy asserted rights over the seigneury on the basis of the succession rights of his brother, Count Amadeus IV of Savoy, who held shares in the fief.^{[8][ReG 7]} He launched a military campaign and captured the castle. Rodolphe, the new Count of Geneva, refused to render homage for the castle and was dispossessed of it, with the fief being granted to Pierre Martin. A conflict between the two men continued until 1260, when the Count of Geneva accepted submission and regained control of the castle.^[8]

The peasants of the Chamonix valley, who were in conflict with the local priory, periodically sought refuge at the castle,^{[ReG 8][2]} with rebels taking shelter there in 1289.^[9]

In 1308, a new peace treaty was concluded between the Houses of Geneva and Savoy. Under its terms, the new Count of Geneva, William III, was required to acknowledge holding “the castles and jurisdictions of Charousse, Alby, Hauteville, and La Corbière” in fief from Count Amadeus V.^{[ReG 9][ReG 10]}

Béatrice of Faucigny pursued a policy of independence and opposition to her uncle, the Count of Savoy. Between 1282 and 1330, the alignment between Béatrice until her death in 1310, then her successor, her grandson Jean II of Viennois, and the Counts of Geneva remained consistent, particularly during the Delphino-Savoyard conflicts from 1310 to 1337. By this time, the castle had lost its strategic significance.^[10] During this period, however, it was pledged as part of the dowry for the marriage of Agnès of Savoy and William III, Count of Geneva, on 31 August 1297.^{[ReG 11]}

After 1330, tensions renewed between the lords of Geneva and Faucigny, restoring the castle’s strategic significance. The châtelain conducted raids on surrounding territories of Faucigny.^[11] The Treaty of 5 January 1355 formalized the acquisition of Faucigny by Count Amadeus VII of Savoy. In 1358, agreements were reached between Amadeus III, Count of Geneva, and Amadeus VI, Count of Savoy, regarding the châtellenie and other lands in Faucigny.

In 1401, the County of Geneva was acquired by Count Amadeus VIII of Savoy. Charousse and its mandement were not included in this acquisition and remained with the heirs of the House of Geneva. In 1409, Matilda of Savoy inherited the rights from her aunt Blanche of Geneva, who had previously inherited them from her mother,^[12][13][14] the dowager Countess Mathilde of Auvergne. The Count of Savoy later negotiated to acquire the remaining rights, and a contract between the heiress—then a minor under the guardianship of her uncle Louis of Savoy-Achaea^[13]—and the duke was signed on 11 January 1417.^[12][14][13]

The stones of the castle are reported to have been reused in the construction of the village of Bay.^[15]

Only fragments of the Château de Charousse’s surrounding walls remain.^[16] The fortress featured a shield wall forming an angle of approximately 140°.^[17]

Due to its location on a mountainside, the castle was accessible only from the east, above a vertical rock face over 100 meters high.^[1][2] The north side was likely defended by a square keep measuring about 10 meters per side, complemented by an enclosure with moats on the north and east sides.^[6] The walls, built on an embankment, were approximately 2.5 meters thick and protected the eastern courtyard, which contained the living quarters, including those of the châtelain.^[2] Each corner of the wall was probably reinforced with wooden defensive structures, estimated at five. Access was through a gate equipped with échauguettes,^[6][2] and the enclosure extended up to 128 meters from east to west.^[2]

Access to the castle was via a path from the village of Bay, which led toward the keep before turning along the eastern side of the enclosure to reach the entrance.^[2]

The castle belonged to:

• Counts of Geneva,^{[ReG 12][ReG 13][ReG 14]} although they remained vassals for this fief to the Counts of Savoy.
  • 1225: Guillaume de Charousse, châtelain in the name of the Counts of Geneva
• 1259: Seized by Peter II of Savoy^{[ReG 11][ReG 9][8]}
  • 1259–1260: Rights transferred to the liegeman Pierre Martin^[8]
• 1260 –?: Returned to the Counts of Geneva in exchange for renewed recognition of homage

The Château de Charousse served as the seat of a châtellenie, or mandement,^[18][19] directly under the authority of the Count of Geneva in the late 14th and early 15th centuries.^[19][20] The châtellenie was administered by a comital châtelain appointed by the count, who exercised administrative and judicial powers.^[19][21]

The châtellenie of Charousse encompassed the castle itself, the fortified house of La Frasse, the small castle (châtelet) of Le Châtelard, the fortified house of Loisin, and the fortified house of Lucinges (also known as the Tower of Lucinge).^[22]

In the 17th century, the coat of arms of the mandement was described as a silver cross on a blue field, accompanied by three red pales on a gold background.^[23]

After its incorporation into the County of Savoy from 1401, the châtelain was an officer appointed for a fixed term, with the authority to be revoked or removed.^[24][25] The châtelain was responsible for administering the châtellenie or mandement, collecting fiscal revenues, and maintaining the castle.^[26] An accounts' receiver sometimes assisted the châtelain by preparing the annual report submitted by the châtelain or his deputy.^[27]
