Château du Buron, French castle located in Vigneux-de-Bretagne

Chateau du Buron is a medieval fortress in Vigneux-de-Bretagne built between 1345 and 1385. The structure displays typical noble house architecture with stone walls and older towers characteristic of the period.

Construction began in 1345 and was completed in 1385 for the Dukes of Rohan. After centuries of family ownership, the castle passed to Madame de Sévigné in the 17th century and moved to the Hersart de La Villemarqué family around 1700, where it has remained.

The castle was linked to the Rohan family for centuries, one of the region's most powerful noble families. Its connection to Madame de Sévigné in the 17th century gave it literary significance among Breton aristocratic residences.

The château is private property of the Hersart de La Villemarqué family and cannot be visited inside; it is seen from outside, across the grass terrace facing the courtyard. The Nantes golf course, created in 1969, encloses the estate on three sides.

The estate has belonged to the Hersart de La Villemarqué family since its sale in 1700, more than three centuries. The Nantes golf course, laid out in 1969, wraps around the grounds on three sides, so the fairways now border the castle's land.
