"Les Granges", it's first and foremost about a tradition of holidays spent in Oléron Island. This tradition finds its roots in the fifties, when Georges Charpentier takes his family to Oléron Island on summer vacaction. On foot fishing trips, beaches and dunes, childhood friendships built over the years will lead Jean-Louis, elder son of Georges, to introduce 20 years later Oléron Island to his fiance and future wife.

The young couples immediately falls under Oléron Island's irresistible appeal, which motivates them to come every year on summer vacation with their children. Oléron's charm, its fauna and flora, its regional food, its traditional architecture will overcome the small family's last hesitations: they end up moving permanently to the Island in 1981.

Their house built on a piece of land called "Les Granges" readily becomes a preferred holiday destination for their friends and relatives. A tradition of hospitality emerges from the desire to reveal Oléron's appeal to newcomers.

Almost 25 years later, François-Xavier, Jean-Louis' elder son, decides to open his house to vacationers in order to introduce them to Oléron Island's treasures.
