the largest triumphal arch in the world, and one of the best-known commemorative monuments of Paris, France. The arch stands at the centre of the Place Charles de Gaulle (formerly the Place de l'Étoile), which is the western terminus of the Avenue des Champs-Élysées. The arch is 164 feet (50 metres) high and 148 feet (45 metres) wide. It was initiated by Napoleon Bonaparte and was designed by Jean-François-Thérèse Chalgrin (Chalgrin, Jean-François-Thérèse). Construction of the arch began in 1806, though work was not completed until 1836. Decorative relief sculptures celebrating Napoleon's victorious military campaigns were executed on the arch by François Rude, Jean-Pierre Cortot, and Antoine Etex. Beneath the arch lies France's Tomb of the Unknown Soldier.
