Origin and history

The Château de Saint-Denis-en-Bugey is a former 13th century castle, the centre of the seigneury and then the Barony of Saint-Denis-le-Chosson. Located in the Ain, it remains today only its square dungeon, restored at the beginning of the twentieth century. The fortress, originally built of wood and land, was rebuilt in stone from 1326, after its destruction by Savoyard troops in 1325. She played a strategic role in the Delphino-Savoyard conflicts, controlling the entrance of the Albarine cluse.

The tower, classified as a historical monument in 1899, is the main vestige of this medieval fortress. It was erected by the dolphins of Vienna to monitor neighbouring Savoyard territories, notably after the Treaty of Chapareillan (1335), which established the Albarine as a border. The castle changed hands several times, passing from the sires of Coligny to the dolphins, then to the Counts of Savoie, before being infused to various vassals from the fourteenth century.

Over the centuries, the castle was partially destroyed, especially around 1600 by the Biron troops during the conquest of the Bresse. The current tower, restored in 1905, preserves architectural elements typical of the 14th century dungeons, such as a summital terrace equipped with a DIY (jet weapon) and windows for archetra. Courtines, now partially visible, linked the tower to a quadrangular enclosure.

The site, owned by the commune, is now enhanced by a historical trail with educational terminals. Animations, such as sound and light shows, are organized to revive its medieval past. The tower is also represented in local frescoes, demonstrating its importance in regional history.

Excavations and archaeological studies revealed that the site was occupied from ancient times, with Gallo-Roman traces. However, the current fortress finds its origins in feudal rivalries between Dauphiné and Savoy, marked by successive reconstructions and property changes, reflecting the political stakes of the region in the 13th and 14th centuries.
