With the beginning of the 20th century come new luxury dream hotels such as the Miramar, the Martinez...
The city modernises with the construction of the sports centre, the installation of the street car, the opening of the post office, the appearance of educational establishments (le lycée Carnot, l'Institut Stanislas), …
All these nice projects are possible only after the terrible First World War (14-18) which changes Cannes into a gigantic hospital.
All the big establishments are then requisitioned.

After the war, the German and English clientele of Cannes diminishes, wheras the Americans are attracted by the Côte d'Azur.
In Cannes, the luxury, the elegance and the exquisiteness are very appreciated.
The number of luxury boutiques multiplies.
Sportswise, the choice is equally raising : Yachting, tennis, petanque, polo, golf, ..., fishing is somehow forgotten a bit.
Little by little, the winter tourisme is letting its place to the summer tourisme, therefore, the summer casino at the Palm Beach is constructed.
One can profit from a large choice of festivities : galas, fireworks, concerts, comedies,... ; so many unavoidable activities leading Cannes to success.

The city council has the idea of creating the " International Film Festival ", the project is started in 1946, after the Second World War (39-45), during which the inhabitants of Cannes have to endure many restrictions and sufferings.
The city comes back up, the lust is regaining its place within the community.
On September 20th, 1946 is the inauguration of the 1st International Film Festival.
It takes place in the Casino Municipal and has enormous success.
Nevertheless, the casino is considered ill-adapted to the Festival, and the Nautic Cercle is destroyed. At its place is constructed the " palais des Festivals ", finished in 1950. In 1979 it is destroyed again and replaced at the site of the Casino Municipal.
Nowadays, this " Film Festival ", second most known event worldwide (after the Olympic games) is the pride and the good reputation of Cannes, city of a thousand subtleties !
