Cannes, France, a city in Alpes-Maritimes province, on the Riviera. It is a fashionable year-round resort built on low hills overlooking the Mediterranean Sea. Cannes is known for its mild climate, luxury hotels, casinos, and elegant homes and villas. A broad promenade with palm trees and sandy beaches follows the Boulevard de la Croisette along the crescent-shaped waterfront. Many cruise ships and private yachts moor in the harbor. Several prominent festivals are held in the city each year, chief of which is the international film festival in May. Cannes was a tiny fishing village for centuries before developing into a resort in the 19th century.
