Two million people visited it the first year it was built, and almost 6 million people a year today.
The Eiffel Tower was designed by the French engineer Alexandre Gustave Eiffel for the Paris Exposition of 1889. People spent 2 years, 2 months and 5 days (1887 to 1889) building it. It was the highest building in the world at that time.
The Eiffel tower has been painted 17 times since it was built. 50 tons of dark brown paint are needed to cover the tower every 7 years. The names of the 72 French scientists are written on the sides of the tower.
