History
Château de La Bâtie-Seyssel is a medieval fortified residence in France, above Barby at the foot of Mont Peney. Formerly called La Bâtie d’Arvey, it was first mentioned in documents in the late thirteenth century and probably replaced an earlier structure. The château became the centre of the lordship, later the châtellenie, of La Bâtie.
The Seyssel lords
The first known owners belonged to the Seyssel family, a major noble lineage of the County and Duchy of Savoy. After the death of Humbert III, Hugues de Seyssel inherited La Bâtie, while his elder brother received the principal Seyssel domain and the fortress of Aix. This division established the junior line known as the Seyssel lords of La Bâtie.
During the fourteenth century, the fief, a feudal holding with associated rights and revenues, extended somewhat beyond the parishes of Barby and Curienne. Aymard de Seyssel received its formal investiture, or confirmation of those rights, in 1343. Several members of the junior line later became involved in legal disputes with the counts of Savoy. Before the end of the fourteenth century, the death of the last member of that line brought La Bâtie back to the senior Seyssel branch.
Changes of ownership
Françoise, the widow of Gabriel de Seyssel, baron of Aix, received the fief in 1517. Charles-Emmanuel de Seyssel, marquis of Aix, later sold it to his mother, Isabeau de La Roche-Andry. After Maurice de Seyssel, marquis of Aix and La Chambre, died on 14 May 1660, a legal judgment assigned La Bâtie to Jacques d’Allinges, marquis of Coudrée. In 1679, d’Allinges sold it to François d’Oncieu, who held offices including president of a chamber of the Court of Accounts and senator of the Savoy Senate.
By letters patent dated 25 March 1699, Victor-Amédée III, king of Sardinia, elevated the lordship of La Bâtie to a marquisate for Guillaume d’Oncieu. The château’s construction and alteration history extends from the thirteenth to the nineteenth century, with major restoration carried out in the sixteenth century.
Seat of the châtellenie
La Bâtie-Seyssel served as the seat of the châtellenie, also called a mandement, an administrative territory governed from a castle in the medieval and early-modern Savoyard system. Its châtelain was a removable officer appointed for a fixed term. He administered the territory, collected its revenues, and maintained the castle. Accounts preserved from Jean de La Fontaine cover the period from 29 September 1503 to 29 September 1504.
The château controlled an ancient Roman road connecting the Combe de Savoie with Seyssel through Chambéry, the Bourget valley, and Aix. The Seyssel lords also held the castles of Saint-Cassin and Aix, which controlled other points along the same route. A fortified house known as La Colombière was associated with the defence of the site.
Modern protection
Château de La Bâtie-Seyssel was partially listed as a historic monument by an order dated 6 April 1972, with protection also recorded in 2023. The protected elements include the façades and roofs, the great terrace, the lower room now called the great salon with its decoration, and the large fireplace of the guard room, which incorporates a relocated Gallo-Roman mosaic. The property remains privately owned.
Remains
Fortifications and western entrance
The château occupies a rocky spur above Barby, overlooking a bend of the Leysse River. Its elongated outer fortified enclosure follows the contours and limits of the spur. A lower defensive enclosure, or fausse-braie, includes an artillery platform known as a boulevard and surrounds a second enceinte. The inner enclosure contained the residential buildings and was defended by a circular master tower, probably dating from the late twelfth or early thirteenth century, together with a semicircular tower dated 1472.
Western gateway and Tour des Orgues
The western approach passes through a multi-level bastion pierced by numerous gunports and reaches an ogival gateway that retains the groove for its portcullis. South of the entrance rises the tall semi-cylindrical Tour des Orgues, built on a sloping glacis. Its summit platform is enclosed by a crenellated parapet carried on corbels and equipped with machicolations, a projecting defensive gallery with openings for dropping missiles or other materials.
An inscription on a stone in the Tour des Orgues states that Pierre de Seyssel, counsellor and chamberlain to his Savoyard lord, had the tower built in 1472. To the north of the western entrance stands the fifteenth-century castle chapel, constructed over the curtain wall and pierced by arrow slits. Its interior contains fourth-century Roman mosaics discovered at Arbin, in the Gallo-Roman villa of Mérande.
Eastern access and residential buildings
The principal entrance lay on the eastern side and was approached through three successive gateways. A square tower with arrow slits and gun loops, together with a circular tower, defended this approach. The first gateway, called the Saint-Antoine Gate, is crowned by a polychrome wooden statue of Saint Anthony. Its ogival arcade survives, as does the vault that supported a guardroom.
Eastern gateways
The second gateway was rebuilt with a semicircular arch in the seventeenth century, and a curtain wall links it to the first gate. The narrow third gateway adjoins the keep and was converted into a window set above ground level.
Residential building
The residential building was reconstructed at the beginning of the sixteenth century and is described as a restoration in a fifteenth-century style. Its façades include mullioned windows and Renaissance doorways with shouldered, decorated lintels. At the centre of the façade, a coat of arms bears the arms of Janus d’Oncieu of the Oncieu family.
An exterior wooden gallery once linked the keep with the polygonal tower and gave access to the first-floor chambers. It was later replaced by a covered gallery. A surviving pillar is topped by a fifteenth-century statue of the Virgin. The kitchen fireplace has an opening approximately eight metres wide beneath a shallow segmental arch.
Towers and keep
Northwestern tower
The northwestern tower is rectangular and dates from the fifteenth century. An attached stair turret serves three storeys of vaulted rooms above the ground floor. The walls are approximately two metres thick, and one corner bears the arms of Pierre de Seyssel.
Round keep
Opposite the northwestern tower stands the round keep, or master tower, probably built in the thirteenth century. It contains three vaulted storeys above a ground floor and has stone walls 2.5 metres thick. A pavilion roof covers the tower, while its upper defensive crown was removed in 1793.
