The construction of the Arc de Triomphe began in 1806 on the orders of Napoleon I to honor the victories of the Grande Armée. Inspired by the great arches of antiquity, this monument combines memorial and symbolism and has always played a key role in the national Republican consciousness, as the torch of the Unknown Soldier from the Great War is lit every night. There is an exhibition explaining the importance of the symbolic arch at the national and international level. The terrace also offers great views throughout the day and night across the city and its great grand boulevards.
