Gâtinais

Gâtinais (French pronunciation: ​[ɡɑtinɛ]; or Gâtine) was a province of France, containing the area around the valley of the Loing, corresponding roughly to the northeastern part of the département of Loiret, and the south of the present department of Seine-et-Marne. Under the Bourbons, the Gâtinais had already been divided between the provinces of Île-de-France and Orléans. In the words of the modern tourist slogan for the "two Gâtinais", it lies between the Seine and the Loire.
