Origin and history

The castle of Miolans, built in the 11th century by the Miolans family on the remains of a Roman oppidum of the 4th century, stands on a rocky spur at 550 meters altitude, controlling the alpine roads towards the Maurienne and Tarentaise. Initially center of a seigneury and then a barony (1497), it became a Savoyard chestnut in the 14th century. Its architecture, reinforced by ditches, towers and defensive chestnut, makes it a remarkable example of medieval fortress adapted to military progress until the 15th century.

Transformed into a state prison in 1564 by Duke Emmanuel-Philibert de Savoie, Miolans was nicknamed the Savoyard Bastille. Organized in twelve symbolic cells (Hell, Paradise, etc.), the prison welcomed political figures or criminals, such as the Marquis de Sade in 1772, who escaped in 1773. The fortress, partially destroyed in 1792 during the French invasion, was sold as a national property before being restored in the 19th century by the Guiter family, with the help of architect Jules Formigé.

The site, classified as Historical Monument in 1944, illustrates the evolution of military and prison functions in Savoie. Its remains, including the St. Peter's Tower (XII century), the quadrangular dungeon (XIII century) and the castral chapel (XV century), offer a unique testimony of feudal and ducal history. Today a private property, part of the castle is open to visit, revealing its strategic role and complex defensive architecture.

The excavations and archives reveal an earlier Roman occupation, with traces of tiles and pottery near the old track from Lyon to Aosta. The family of Miolans, close to the Counts of Savoy, retained its influence there until 1523, when the Duke took over to make it a strong place. The castle, besieged several times (1536, 1690), lost its military role after 1559, marking the beginning of its prison vocation.

Among the famous prisoners were the historian Pietro Giannone (1736–37) and Abbé Lavini, a banknote counterfeiter. The prison, organized in thematic cells, reflects a strict prison hierarchy. After 1792, the site fell into ruins before being saved by private restorations, thus preserving its architectural heritage and its link to Savoyard history.

The castle of Miolans, with its three enclosures and successive ditches, embodies the adaptation of medieval fortresses to political and military issues. Its panorama, stretching from Mont-Blanc to Vercors, recalls its role as a strategic lock between the Savoy and the Alpine valleys, while symbolizing the power of the lords of Miolans and the Dukes of Savoy.
