Château-Dauphin is a medieval fortress located in the municipality of Pontgibaud in the Puy-de-Dôme department of France.
The castle derives its name from the heraldic emblem of its 12th-century builder, Robert I, Count of Auvergne, whose coat of arms featured a dolphin (dauphin). Originally constructed, it underwent modifications in the 15th century by Gilbert III Motier de La Fayette, who enhanced its defenses and expanded the keep. Abandoned in the 17th century in favor of a more comfortable residence and subsequently damaged during the French Revolution, the castle was eventually restored in the 19th century under the supervision of Count César III of Pontgibaud.
Since 1756, the castle has been occupied by the family of a King’s musketeer, César I de Moré. The current proprietors, Count and Countess Gabriel de Germiny, are direct descendants of this lineage. The castle, along with its gardens and museum, is accessible to the public.
