château des Allymes

The Château des Allymes is a medieval fortress located in the hamlet of Brey-de-Vent within the Ambérieu-en-Bugey commune in the Ain department of France. Constructed initially in the early fourteenth century and later rebuilt and restored in the sixteenth and nineteenth centuries, it stands as the only example of a medieval fortress in the Bugey region. Built on a hillside at an altitude of approximately 650 meters, it commands an exceptional view of the plain of Bresse, the Dombes, and the Ain river plain. The site was classified as a monument historique on July 20, 1960, and has been the property of the commune of Ambérieu-en-Bugey since 1984.

The fortress originated as an earth and wood fortification constructed around 1305 by Dauphin Humbert I of Viennois to counter a similar Savoyard structure built at Luisandre. Between 1312 and 1318, Dauphin Jean II of Viennois replaced it with a stone castle, a project interrupted by a papal truce from 1314 to 1315. The master masons, brothers Perronet and Guillemet de Hières, oversaw the construction. In 1335, following the Treaty of Chapareillan, the last Dauphinois chatelain, Guy de Lutrin, surrendered the castle to the Count of Savoy, moving the frontier and stripping the site of its strategic border value. Amadeus VI of Savoy later granted the castle to François Nicod in 1354. Through the 1477 marriage of Claudine François to Humbert de Lucinge, the Lucinge family took possession. Partially demolished in 1557 due to a conspiracy led by Charles de Lucinge, the castle was restored and fitted with a Renaissance residence around 1565 after the Duke of Savoy recovered the territory. The 1601 Treaty of Lyon permanently returned the castle to France, prompting René de Lucinge, the Savoyard ambassador, to swear allegiance to Henri IV. The castle subsequently passed through the Suduyrand, Estienne, and Dujat families before the French Revolution. Adolphe de Tricaud d'Ambérieu inherited the deteriorating site and began restorations in 1847. The De Tricaud family sold the property to a Mr. Peyre in 1959, just before its historical monument classification in 1960.

The castle functions as a historical and cultural site open to visitors year round, hosting both temporary and permanent exhibitions. Its primary interpretive focus centers on the history of the fortress itself and the legacy of René de Lucinge, a Renaissance era historian, man of letters, and Savoyard ambassador. A permanent exhibition within the castle walls details his life, diplomatic career, and literary contributions, utilizing the historical environment to contextualize the regional shifts between the Dauphiné and Savoy.

The most significant historical artifacts held at the site are the architectural elements and written records left by René de Lucinge. His writings, which document his life and work, are a central feature of the permanent exhibition. Architectural holdings of note include the Gothic living quarters, the Romanesque style cylindrical donjon, halls featuring well preserved woodwork, and a restored barbican defending the main entrance.

Representative of a medieval stone stronghold, the castle is predominantly constructed from rubble stone. Its quadrangular enclosure is flanked by a large cylindrical donjon, begun around 1351, and a round tower, all connected by four curtain walls. A substantial outer wall measuring 90 meters in length terminates in a lookout tower that once protected an adjoining town. The interior features a sixteenth century residential wing connected by a spiral staircase, Gothic quarters, and a restored barbican at the main entrance. Situated to the southwest of Mount Luisandre, the hillside site provides a commanding defensive position over the surrounding plains.

The Château des Allymes is located in the hamlet of Brey-de-Vent, accessed via the hamlet of Les Allymes, within the Ambérieu-en-Bugey commune. It has been owned by the village of Ambérieu-en-Bugey since 1984 and is managed and maintained by an association of friends of the castle. The site is open to visitors throughout the year. Ongoing restoration programs, including work on the keep and Gothic quarters in 1964, the round tower roof in 1977, the four curtain walls in 1984, and the barbican in 1991, have preserved the structure for public access.
