Situated at the Place de l’Etoile, overlooking the Champs-Elysées, the Arc de Triomphe is the biggest arch in the world. It was commissioned by Napoleon in 1806 to celebrate his victory at Austerlitz. The architects Chalgrin, Joust and Blouet all worked on the monument. Sculptures were designed by Cortot, Rude, Etex, Pradier and Lemaire. Beneath the arch is the Tomb of the Unknown Soldier, and each evening at 6:30pm its flame is rekindled. From the top of the monument, visitors benefit from a panoramic view of Paris, during the day and at night, and two viewpoint indicators. A museum retracing the history of the Arc de Triomphe, situated within the structure, completes the visit.
