Eiffel

Named after its designer, Gustave Eiffel, the iron lattice tower was initially intended as the arch entrance to the 1889 Exposition Universelle which was to celebrate the 100th year anniversary of the French Revolution. The structure is 1,063 ft tall (or 324 meters) which includes the antennas and 3 levels for visitors. It was built with about 7,300 tons of iron framework with a total weight of 10,000 tons. There are 18,000 parts connected by 2.5 million rivets. When it was completed, the tower was deemed as an eyesore for many and Eiffel had the permit to let it stand for 20 years. The city had planned to dismantle the tower but let it stand after discovering that the structure proved to have a potential for valuable communication. The tower has been a symbol of Paris and France and welcomes about 7 millions of visitors per year.
