Stéphen Liégeard is at the origin of the expression Côte d'Azur, which he used in his eponymous book of 1887. It replaced the name Riviera, born from the practice of winter resort established on the coast of Eastern Provence from 1750 by the English aristocracy in search of winter mildness. Liégeard then defined the Côte d'Azur as the coastal strip between Marseille and Italy. Today, its western limit is vaguer and stops in Saint-Tropez for some purists and in Bandol for the magazine Géo. The Côte d'Azur is restricted to the departments of Var and Alpes-Maritimes for the Guide du Routard but sticks to the definition of Stéphen Liegeard in the Larousse dictionary.
