Paris is the French-speaking city famous for the New Year's Eve street party on the Champs-Élysées. The grand avenue, extending between the Place de la Concorde and the Arc de Triomphe, has long been associated with large public gatherings and year-end celebrations.
Revelers traditionally gather along the avenue to count down to midnight, while the Arc de Triomphe may serve as a dramatic projection or illumination surface in official celebrations. The exact program, crowd rules, and security arrangements can change from year to year, so the avenue itself is the stable identifying feature rather than one permanent fireworks format.
The Champs-Élysées is also a major ceremonial route for national events, including Bastille Day celebrations and victory parades. It is not the Eiffel Tower: that landmark is another iconic Paris setting and may appear in New Year's broadcasts, but the named street-party location is the Champs-Élysées.
