With less than three months to go before the opening of the Paris Olympic and Paralympic Games, the conditions of this global event are finally taking shape. But does the reality of the Games match the promises made when Paris submitted its bid 8 years ago?

Several metro lines, which were due to be extended or opened to traffic, will also not be ready until after the Games.

From the opening ceremony to sporting venues and swimming in the Seine, Le Monde takes a look at how the promises of the Paris Olympics stack up against the reality of the upcoming Games in our 4-minute video.
