The Château des Allymes is a thirteenth-century castle which was rebuilt in the sixteenth century and restored in the nineteenth. It is located in the hamlet of Les Allymes, in the Ambérieu-en-Bugey commune in the Ain department of France, in the Rhône-Alpes region.
The castle was built by the Dauphin of Viennois to protect the people from attacks that were ravaging the country. It is approached by the hamlet of Brey-de-Vent, and is the only example of a medieval fortress in Bugey.
On the 20th of July 1960 the Château des Allymes was classed a monument historique.
