Which famous landmark of France is hidden in the picture?

The Arc de Triomphe de l'Étoile (literal translation: "Triumphal Arch of the Star") is one of the most famous monuments in Paris, France.

The monument is standing at the western end of the Champs-Élysées at the centre of Place Charles de Gaulle, formerly named Place de l'Étoile — the étoile or "star" of the juncture formed by its twelve radiating avenues. The location of the arc and the plaza is shared between three arrondissements, 16th (south and west), 17th (north) and 8th (east). The Arc de Triomphe honours those who fought and died for France in the French Revolutionary and Napoleonic Wars, with the names of all French victories and generals inscribed on its inner and outer surfaces. Beneath its vault lies the Tomb of the Unknown Soldier from World War I.

As the central cohesive element of the Axe Historique (historic axis, a sequence of monuments and grand thoroughfares on a route running from the courtyard of the Louvre to the Grande Arche de la Défense), the Arc de Triomphe was designed by Jean Chalgrin in 1806, and its iconographic program pits heroically nude French youths against bearded Germanic warriors in chain mail.
