Olympic Paris is an Olympic city for the third time since the Games were reinstated in 1896. The challenges facing the French capital are not exceptional and there is much to learn from previous experiences in organizing this type of mega-events.

The key to successful Games is planning, not only of the event itself, but of its legacy in the medium and long term. Many cities take advantage of the planned Olympic works to rehabilitate sensitive or disused areas, seeking to provide them with better housing and services.
