The pride of Napoleon\'s victories, the Arc de Triomphe, whose first stone was laid in 1806 at the top of the Champs-Élysées, is, along with the Eiffel Tower, one of the most visited monuments in the French capital. Wanted by an emperor, inaugurated under the reign of a king (Louis-Philippe) and sanctuarized by the Republic, this patriotic temple polarizes the passions of a whole nation. A historical portrait before \"packaging\", which teems with anecdotes and unsuspected details.
