The Arc de Triomphe de l'Étoile is one of the most famous monuments in Paris, standing at the western end of the Champs-Élysées. Commissioned by Napoleon in 1806 after his victory at Austerlitz, it honors those who fought and died for France in the French Revolutionary and Napoleonic Wars. The names of all French victories and generals are inscribed on its inner and outer surfaces. Beneath its vault lies the Tomb of the Unknown Soldier from World War I, where the first eternal flame in Western Europe was lit in 1923. The arch is the center of a 'star' (étoile) of twelve radiating avenues. A little-known fact is that the arch is so large that in 1919, pilot Charles Godefroy successfully flew his Nieuport fighter plane through the center of it to honor the end of WWI.
