The history of Château d’Issan consists primarily of a long list of property transmissions and legacies. By inheritance and marriage, the estate has been handed down from owner to owner, and all of them have contributed in their own way to its renown and helped to forge its unique character. In the 12th century, the property was a fiefdom with the name at that time of La Mothe-Cantenac, before becoming Théobon Manor, when a female heir married a lord with the same name.
