Château de la Bretonnière, Historical castle in Vigneux-de-Bretagne, France.

Château de la Bretonnière is a castle northwest of the village of Vigneux-de-Bretagne, set within an expansive park. The property includes outbuildings used for events and a pond within the grounds.

The estate began as a hunting lodge of the Dukes of Rohan, possibly dating to the 15th century. It then passed to the Charette family, next to the Monti de Rezé, and later to a M. d'Izarn. During World War II it was used as an espionage school. It now belongs to the de la Grandière family.

The château's name comes from the Bretonnière estate, and the building is still owned by the de la Grandière family. It now hosts receptions, seminars and festive meals such as weddings, so the interiors are seen mainly by guests attending these events.

The château stands 1.5 km northwest of the village centre of Vigneux-de-Bretagne, reached by road through the wooded estate. The grounds cover 50 hectares of tall forest bordering a pond of more than 1.5 hectares. The building is a private residence that hosts receptions, seminars and festive meals such as weddings, so visits are tied to a booked event rather than to regular opening hours.

The source records only that the château was used as a spy school during World War II, without naming the organisation or the years. The building itself is a former hunting lodge of the Dukes of Rohan, and a tower from the 16th century survives beside the 18th- and 19th-century Neo-Gothic work.
