Eiffel had a permit for the tower to stand for 20 years, meaning it would have had to be dismantled in 1909, when its ownership would revert to the City of Paris. The City had planned to tear it down (part of the original contest rules for designing a tower was that it could be easily demolished) but as the tower proved valuable for communication purposes, it was allowed to remain after the expiration of the permit.
To this day, the Eiffel Tower has been completely repainted every 7 years.
How long to paint it?: 15 months. 60 tons of paint, 25 painters using only brushes.
Color: "Tour Eiffel brown" in three shades, with the lightest shade at the top and the darkest at the bottom.
