Arc de Triomphe de l'Étoile
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. Its design was inspired by the Roman Arch of Titus. The Arc de Triomphe is built on a large scale.
It was the tallest triumphal arch in existence until the completion of the Monumento a la Revolución in Mexico City in 1938, which is 67 metres (220 ft) high. The Arch of Triumph in Pyongyang, completed in 1982, is modelled on the Arc de Triomphe and is slightly taller at 60 m (197 ft).
Beneath the Arc is the Tomb of the Unknown Soldier from World War I. It has the first eternal flame lit in Western and Eastern Europe. It burns in memory of the dead who were never identified (now in both world wars).
A ceremony is held at the Tomb of the Unknown Soldier every 11 November on the anniversary of the armistice signed by the Entente Powers and Germany in 1918. The slab on top have the inscription ICI REPOSE UN SOLDAT FRANÇAIS MORT POUR LA PATRIE 1914–1918 ("Here lies a French soldier who died for the fatherland 1914–1918").
