For the past four centuries, this granite fort on the Croisic peninsula has stood guard over the moods of the Atlantic Ocean and the ramparts, moats and drawbridges of this look-out post of the savage coast are all still standing since the days of Vauban. Built to resist storms and attacks, today, behind this tough exterior there is charming oak panelling, sweet-smelling gardens, a sheltered swimming pool and a kitchen garden. The chef uses herbs and vegetables from the garden in his inventive cuisine that usually includes fresh seafood. For dessert, the slightly salty homemade caramel is a real treat.
