In a third meaning, "France" refers specifically to the province of Île-de-France (with Paris at its centre) which historically was the heart of the royal demesne. This meaning is found in some geographic names, such as French Brie ("Brie française") and French Vexin ("Vexin français"). French Brie, the area where the famous Brie cheese is produced, is the part of Brie that was annexed to the royal demesne, as opposed to Champagne Brie ("Brie champenoise") which was annexed by Champagne. Likewise, French Vexin was the part of Vexin inside Île-de-France, as opposed to Norman Vexin ("Vexin normand") which was inside Normandy.
