Now one of the most recognizable structures on the planet, the Eiffel Tower underwent a major facelift in 1986 and is repainted every seven years. It welcomes more visitors than any other paid monument in the world—an estimated 7 million people per year. Some 500 employees are responsible for its daily operations, working in its restaurants, manning its elevators, ensuring its security and directing the eager crowds flocking the tower’s platforms to enjoy panoramic views of the City of Lights.
