About the location (from Wiki):
The Arc de Triomphe is one of the most famous monuments in Paris. It stands in the centre of the Place Charles de Gaulle, at the western end of the Champs-Élysées. There is a smaller arch, the Arc de Triomphe du Carrousel, which stands west of the Louvre. The Arc de Triomphe (in English: “Triumphal Arch”) honours those who fought and died for France in the French Revolutionary and the 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. The monument stands 50 metres (164 ft) in height, 45 m (148 ft) wide and 22 m (72 ft) deep. The large vault is 29.19 m (95.8 ft) high and 14.62 m (48.0 ft) wide. The small vault is 18.68 m (61.3 ft) high and 8.44 m (27.7 ft) wide. It is the second largest triumphal arch in existence (after Arch of Triumph in Pyongyang). Its design was inspired by the Roman Arch of Titus. The Arc de Triomphe is so colossal that three weeks after the Paris victory parade in 1919, marking the end of hostilities in World War I, Charles Godefroy flew his Nieuport biplane through it, with the event captured on newsreel.
