It was first built in 1889 for the 100th anniversary of the French Revolution; now it’s one of the greatest tourist attractions in the world.
The design of the tower was actually based from a competition. Many architects had designed proposals for what the building would look like, but in the end the Eiffel Tower design (which was made by Alexendre-Gustave Eiffel, who was a chemical engineer) was selected. After its construction, it was to be dismantled; however due to the many protests from the civilians and tourists, it was decided that the structure was to stay. Starting from the 1900’s, the tower was used as a transmission tower once radios and televisions were widespread. Also, it was used for several scientific experiments involving temperature, pressure and more.
During the construction of the tower, the Eiffel Tower was the tallest man-made structure in the world (986 feet at the time. The height was later increased to 1052 feet because of an addition of a television antenna), and was able to stand against wind pressure of 82 PSF (at the top). During this time, people had thought that the look of the structure was unappealing; “an eyesore”. Once the structure was made, it took up 328 feet of space for each side of its square base, and weighed approximately 7300 tons.
