The Alpes-Maritimes is the second most-visited region of France. Its ritzy backstory renders it awash with cultural sights, several of them once the private villas of the ostentatiously loaded. Even Nice, France’s fifth-largest city, hosts more museums than any other French town outside Paris. Throw in historic hotels and art galleries, and you have an edifying panorama like no other. Even architectural gems from government buildings to banks and train stations (like the recently renovated Nice-Ville ) have artistic merit.
Cap Moderne 
The recently reopened seaside homes of architects Eileen Gray (Villa E-1027) and Le Corbusier (Le Cabanon) highlight the avant-garde atmosphere of the 1930s and 1950s. Learn more in the exhibition area that opened next to Roquebrune station in 2016.
Villa les Camelias
The suburb of Cap d’Ail was built as a ritzy French extension of Monaco. Villa les Camelias is a recently opened local history museum dedicated to les années folles. See photos, letters and even the casino chips of the jeunesse dorée.
Villa Santo Sospir
In 1950, Parisian socialite Francine Weisweiller invited artist Jean Cocteau to her Cap-Ferrat home for dinner. He ended up staying for 12 years, daubing the villa from head to toe in dreamy frescoes, which can be visited with the villa’s kindly housekeeper Eric.

Galerie des Bains-Douches
The ramparts that ring Antibes once housed bunkers, barracks and materiel. In 1935 a section of the vaults was converted into public baths, which later became a public gallery of regional contemporary art.
Musée de la Castre
Cannes ’ artistic pretentions are strictly limited: who needs culture when you can saunter half naked into Chanel? But the Musée de la Castre, located on the heights of Le Suquet, has a fine selection of Côte d’Azur scenes painted a century ago.
