Haut-Brion story starts during the 14th century. At that time this estate appears to have been centred around a manor house entitled Aubrion, a name which may relate to a long-forgotten proprietor. The estate enjoyed a number of different owners but, somewhat curiously, in 1509 it came into the hands of Jean de Ségur, a member of the same Ségur family that later would take ownership of many of the top estates of the Médoc, including Lafite and Latour. Clarence Dillon, an American banker purchased the estate in 1935. In 1975, control passed to Clarence's granddaughter Joan, who first married Charles de Luxembourg.
