Aaah Paris! The Eiffel Tower, Notre-Dame, Montmartre, the Arc de Triomphe! Without forgetting the sumptuous avenue of the Champs-Elysées! Symbol of the Parisian decor, it sees thousands of people wandering every day enjoying the beautiful restaurants, strolling through the theatres and cinemas or strolling in the shade of Haussmann-style buildings and going to the department stores. However, the "most beautiful avenue in the world" is nowadays in the grip of the century's evil: cars, noise, pollution, mass tourism, globalization of the commercial offer, neglected gardens are detrimental to its use. The "Champs-Elysées" exhibition retraces the history of the avenue, from its creation by Le Nôtre in 1664 to its major tourist role in Paris today. It questions this evolution and its current problematic state. As part of an awareness of the need for change in the context of the environmental crisis, demographic acceleration and growing inequalities, it re-examines the potential of the area. Thus, thanks to this exhibition, the Champs-Elysées Committee invites everyone to question the reconciliation between local use and contemporary urban issues and the actions to be implemented to improve the practice of this emblematic avenue.
