Grignan is a small village in France which specializes in making wine and has a long history

As a result of several archaeological excavations in Grignan, it has been proven that the rocky promontory of Grignan has been occupied since the Iron Age has been recorded. A former Bronze Age society has been buried here, as well as Roman occupation in the fifth and sixth centuries. It has been argued that historians have noticed that in the year 1035, in the Cartulaire of the Abbey of Saint-Chaffre in the Haute-Loire, there was a reference to a castle called Gradignanum, which was an obscure castle. As the castle evolved over the course of the next century, its name gradually evolved into Grainan Castle (1105), then Graigna Castle, and finally Grazinam Castle ... The origins and history of the castle are little known at the moment, nor are we sure who constructed it. Some time around the year 1030, it has been established that a certain Christophe de Grignan actually existed, and in 1035, the cartulary of Saint-Chaffre, makes reference to a Rostagnus de castello Gradignano, a charter of the castle of Grignan.
