Is Île-de-France really an island without a sea? Take an express dive into the history and mysteries of the name that shapes the identity of France's most effervescent region.

Mystery, history and a touch of linguistics: here's the secret behind the name ofÎle-de-France, the flagship region surrounding Paris. Let's face it, talking about an "island" when no ocean borders its 12,000 km² is intriguing, isn't it?

An island without a sea?

The most widespread explanation takes us back to the Middle Ages.Île-de-France was so named because of the rivers that surround it: the Seine to the south, the Oise to the west, the Marne to the east and the Aisne to the north. From a bird's eye view, this natural grid gives the region the appearance of an island in the heart of France.

What if it was a question of language?

Another hypothesis takes us back to the region's Frankish roots. The term comes from the expression"Liddle Franke", meaning "Little France" in the Frankish language. Over time, the pronunciation evolved into Île-de-France.

From "Pays de France" to "Île-de-France

Although the Franks left their mark on the history of the name, it wasn't until 1387 that the expression appeared for the first time, in Froissart's Chroniques, replacing the old "Pays de France". And it wasn't until 1976 that the appellation became official to designate the administrative region.

Between geography and history,Île-de-France carries with it the past of the Franks and the heritage of a strategic territory, long before it became the most populated and visited region in France!
