Origin and history

The castle of Boulogne, founded in the 11th–12th centuries, was originally a medieval fortress located in the commune of Saint-Michel-de-Boulogne, in the department of Ardèche. Its remains, now classified as historical monuments, bear witness to primitive defensive architecture, with a square dungeon and a chapel, later reinforced by three round towers and courtines in the 14th century. This castle was the heart of one of the twelve baronies of Vivarais, playing a strategic and political role in the region.

In the 14th century, Raoul de L'Estrange acquired the castle in 1384, then modernized it with a family heritage. The fortress underwent a major transformation around 1510 under the impulse of Marie de Langeac, wife of the Baron, who made it a Renaissance residence. This redesign includes a guard room, stables, and a portal decorated with sculptures, reflecting the artistic influence of the time. The castle, which remained intact until the Revolution, was then dismantled stone by stone.

The marriage in 1620 between the Baron of L'Estrange and Paule de Chambaud, Baroness of Privas, linked the castle to the Wars of Religion, culminating with the siege of Privas in 1629 by the troops of Louis XIII. Although the castle survived these conflicts, its ruins, now consolidated, recall its feudal and reborn past. Ranked a historic monument in 1915, the site retains remarkable architectural elements, such as the chestnut and its carved pediment.

Regular excavations and consolidations preserve this heritage, offering an overview of the evolution of castles in aristocratic residences. The remains, dominated by towers and dungeon, illustrate the transitions between the Middle Ages and Renaissance, while stressing the strategic importance of the family of L'Estrange in local history.
