The Château de l’Hermine in Vannes, Brittany, is a historic site that has undergone significant transformations over the centuries. Originally constructed between 1380 and 1385 by Duke Jean IV of Brittany, it served as a ducal residence and was integrated into the city’s fortifications.

In the late 18th century, the original medieval structure was replaced by the Hôtel Lagorce, a neoclassical mansion built by Julien Lagorce, a local pastry chef. This building has since served various functions, including as an artillery school, the Morbihan treasury, and the Brittany Cultural Institute.

Recent archaeological excavations have uncovered remnants of the original 14th-century castle beneath the current structure, revealing parts of the ducal residence and its ornate façade. Plans are underway to transform the Château de l’Hermine into a new Museum of Fine Arts, aiming to preserve its historical significance while providing a modern cultural space.​
