Fifty-five hectares (136 acres) at the time of the 1855 classification, fifty-five hectares today: the walled vineyard of Calon Ségur is a rare example of consistency of terroir throughout the centuries.

Behind the thick stoned wall, the single block of vines stretches around the Chartreuse with the eternal parcels of L’Enclos right at its feet. For the specialists, this is historical heritage.
