The Côte d'Émeraude (Breton: Aod an Emrodez; lit.'Emerald Coast') is a name given to a part of the English Channel coast of eastern Brittany near the border with Normandy in France.
Etymology
Lawyer and historian Eugène Herpin coined the name Côte d'Émeraude in 1890. He was inspired by the "symphonie" of the colours of the sea and shore. The name was inspired by the branding success of the Côte d'Azur in encouraging tourism and development.[1][2]
