Château de Brangues, Heritage castle in Brangues, France

Château de Brangues is a pleasure house of the 17th and 18th centuries built over a 14th-century fortified house, whose round tower with two-metre-thick walls survives in the north-east corner. Three wings enclose a trapezoidal courtyard, giving the plan its P shape. The pale stone facades with terracotta roofs stand on a hill at the edge of the village, and an orangery pavilion borders the drive.

The Rossillon family initiated construction in the 14th century with a fortified tower that would serve as the building's core. The Bathernay family later expanded the structure in the late 15th century.

The castle is sometimes called "Domaine Paul Claudel". Since 1976 the property has hosted the Rencontres de Brangues, and today the association Les Amis du château de Brangues organises conferences, concerts, exhibitions and performances there, with troupes such as Les Tréteaux de France and the Théâtre National Populaire de Villeurbanne taking part in the annual festival.

The castle lies roughly one hour away from both Lyon and Grenoble, making it accessible for a day trip from either city. Full interior visits happen during Heritage Days, though the tomb of Paul Claudel remains accessible year-round.

Stendhal read the Gazette des Tribunaux report of the 1827 "Berthet affair" in Brangues on 28 December 1827; the case, set in the village and its rebuilt church, inspired Le Rouge et le Noir, whose château is often linked to Brangues.
