The Château de Commarin in the commune of Commarin in the Côte-d'Or département, Burgundy, France, has passed through 26 generations in the same family; never sold, though it has often passed through heiresses, Commarin today is a seat of the comte de Vogüé. It has been classed a Monument Historique since 1949.
Though the site probably has its origins in a Gallo-Roman villa, Commarin is first mentioned, as a maison forte, in a document of 1214. Its seigneurs were a cadet branch of the seigneurs of Sombernon, from the lineage of the first Dukes of Burgundy. In 1346 Jean and his son Jacques de Cortiamble, chamberlain to Philip the Bold, duke of Burgundy, rebuilt Commarin as a fortified seat; the size and disposition of this moated stronghold established the placement and size of the future rebuildings.
