The origin of the domain dates back to Gallo-Roman times. In the 14th century, English Guyenne period, it was owned by Sir Robert de Knolles, Governor of Guyenne, and remained in the Canolle family (Frenchization of Knolles) until it was acquired by Edouard Dubois-Challon, then owner of Ausone . The wine, cru "Canolle" then "Bélair", ranks first among the wines of St Emilion in the 18th century. The 1802 vintage is bottled at the Château, a first for the great Bordeaux wines .
