Arc de Triomphe / Triumphal Arch

The Arc de Triomphe (Arc de Triomphe de l'Étoile) is one of the most famous monuments in Paris. It stands in the centre of the Place Charles de Gaulle (originally named Place de l'Étoile), 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 Arc de Triomphe is the linchpin of the historic axis (Axe historique) – a sequence of monuments and grand thoroughfares on a route which goes from the courtyard of the Louvre, to the Grande Arche de la Défense. The monument was designed by Jean Chalgrin in 1806, and its iconographic program pitted heroically nude French youths against bearded Germanic warriors in chain mail. It set the tone for public monuments, with triumphant patriotic messages.

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.

The Arc is located on the right bank of the Seine at the centre of a dodecagonal configuration of twelve radiating avenues. It was commissioned in 1806 after the victory at Austerlitz by Emperor Napoleon at the peak of his fortunes. Laying the foundations alone took two years and, in 1810, when Napoleon entered Paris from the west with his bride Archduchess Marie-Louise of Austria, he had a wooden mock-up of the completed arch constructed. The architect, Jean Chalgrin, died in 1811 and the work was taken over by Jean-Nicolas Huyot. During the Bourbon Restoration, construction was halted and it would not be completed until the reign of King Louis-Philippe, between 1833 and 1836, by the architects Goust, then Huyot, under the direction of Héricart de Thury. On 15 December 1840, brought back to France from Saint Helena, Napoleon's remains passed under it on their way to the Emperor's final resting place at the Invalides. Prior to burial in the Panthéon, the body of Victor Hugo was exposed under the Arc during the night of 22 May 1885.

The sword carried by the Republic in the Marseillaise relief broke off on the day, it is said, that the Battle of Verdun began in 1916. The relief was immediately hidden by tarpaulins to conceal the accident and avoid any undesired ominous interpretations[citation needed]. On 7 August 1919, Charles Godefroy successfully flew his biplane under the Arc. Jean Navarre was the pilot who was tasked to make the flight, but he died on 10 July 1919 when he crashed near Villacoublay while training for the flight.

Following its construction, the Arc de Triomphe became the rallying point of French troops parading after successful military campaigns and for the annual Bastille Day Military Parade. Famous victory marches around or under the Arc have included the Germans in 1871, the French in 1919, the Germans in 1940, and the French and Allies in 1944 and 1945. A United States postage stamp of 1945 shows the Arc de Triomphe in the background as victorious American troops march down the Champs-Élysées and U.S. airplanes fly overhead on 29 August 1944. After the interment of the Unknown Soldier, however, all military parades (including the aforementioned post-1919) have avoided marching through the actual arch. The route taken is up to the arch and then around its side, out of respect for the tomb and its symbolism. Both Hitler in 1940 and de Gaulle in 1944 observed this custom.

By the early 1960s, the monument had grown very blackened from coal soot and automobile exhaust, and during 1965–1966 it was cleaned through bleaching.

In the prolongation of the Avenue des Champs-Élysées, a new arch, the Grande Arche de la Défense, was built in 1982, completing the line of monuments that forms Paris's Axe historique. After the Arc de Triomphe du Carrousel and the Arc de Triomphe de l'Étoile, the Grande Arche is the third arch built on the same perspective.
