 In Belgium, a strong French architectural influence is evident in the seventeenth-century Château des Comtes de Marchin and the eighteenth-century Château de Seneffe.There are many estates with true châteaux on them in Bordeaux region, but it is customary for any wine-producing estate since the 19th century, no matter how humble, to prefix its name with "Château".This term became the default way of designating an estate in Bordeaux, in the same way that Domaine did in Burgundy.
