The Arc de Triomphe de l'Etoile, the world's largest triumphal arch, forms the backdrop for an impressive urban ensemble in Paris.
The monument surmounts the hill of Chaillot at the center of a star-shaped configuration of 12 radiating avenues.
It is the climax of a vista seen the length of the Champs Elysées from the smaller Arc de Triomphe du Carrousel in the Tuileries gardens, and from the Obélisque de Luxor in the place de la Concorde.
Since 1920, the tomb of France's Unknown Soldier has been sheltered underneath the arch.
Its eternal flame commemorates the sacrifices of the two world wars, and is rekindled every evening.
