Origin and history

The castle of Feissons, also called Feissons-sous-Briançon, is an ancient fortified house built in the 13th century in the heart of the eponymous seigneury. Located on a steep mound at Feissons-sur-Isère (Savoie), it was originally part of the Viscounts of Briançon, a powerful family of Tarentaise attested as early as 900. According to legend, a first castle, destroyed in 1082 by Humbert II de Savoie to suppress acts of banditry, preceded the present fortress. The current remains include a 13th century cylindrical dungeon and a 16th century quadrangular lodge, reflecting its architectural and strategic evolution.

Between the 13th and 15th centuries, the fief frequently changed hands: Briançon's family in 1250, the Conflens in 1357, and then the Duyns (teachers of Val-d In 1505 Jean de Duyn, Viscount of Tarentaise, obtained the right to erect patibular forks there, symbolizing his judicial authority. The castle was taken and dismantled twice during the Franco-Savoyard wars: in 1536 by François I, then in 1600 by Henri IV, marking the French occupation of the Duchy of Savoy.

In the 17th century, the seigneury was erected as a county (1680) for the benefit of Charles-Victor-Joseph de Saint-Thomas, before being infused with the inhabitants of Feissons in 1700. The architect Étienne-Louis Borrel (19th century) described a hybrid building, both manor and fortress, protected by a 12 metre ditch and a 26 metre high dungeon. Its defensive elements (tours, round road) and residential elements (renaissance logis) illustrate its dual military and seigneurial role in the Tarentaise Valley.

The original structure, partially destroyed, included a barlong enclosure enclosing the medieval dungeon and a house flanked by round turrets. The dungeon, which was 2.80 metres thick at its base, was home to domestic facilities (carried out, latrines) and a crenellated platform. The house, dated 1536, contained cut stone bays and internal communication with turrets. These remains, though fragmentary, bear witness to the strategic importance of the site at the borders of Savoy and Dauphiné.

Historical sources, such as the works of Stephen-Louis Borrel or Michèle Brocard, underline the role of the castle in local conflicts and its integration into the feudal tarin network. Its gradual destruction, linked to wars and the abandonment of military functions, made it a symbol of the struggles of influence between Savoy and France. Today, its ruins offer a glimpse of Savoyard castral architecture, between medieval heritage and Renaissance adaptations.

The seigneury of Feissons, built in late county, reflects the political changes of Savoy at the dawn of modern times. The alienation of the fief from the inhabitants in 1700 marked a transition to community management, rare for the time. This particular status, combined with its geographical position near Notre-Dame-de-Briançon, makes it a case of study for the history of local institutions in Tarentaise.
