This engineering feat built for the 1889 Exposition Universelle was intended to be a temporary structure and is now one of the most recognizable landmarks in the world. It was saved as it was the location of the first electric telegraph on November 5, 1898 by Edouard Branly, a respected physics professor. Every seven years the Eiffel Tower gets a touch up and requires 60 tons of paint to cover over 250,000 square meters. Now that is a lot of paint!
Over 7 million people visit the tower each year, some like the day view and others are mesmerized by the beauty in the night.
Tip: Reserve tickets online in advance (2-6 months) if you want to get to the top.
