who is buried under the arc de triomphe de l'etoile
Arc de Triomphe Beneath the Arc is the Tomb of the Unknown Soldier from World War I. Interred on Armistice Day 1920,[14] it has the first eternal flame lit in Western and Eastern Europe since the Vestal Virgins' fire was extinguished in the fourth century. It burns in memory of the dead who were never identified (now in both world wars).
