The Eiffel Tower was built in Paris, France between 1887-1889 as the entrance to the 1889 World's Fair. It was the tallest structure in the world at the time at 1,000 feet tall. Some key facts are that it only took 2 years and 46 days to build, it has withstood occupying forces during both World Wars, and now receives over 250 million visitors. It was originally intended to be dismantled after 20 years but has remained as an iconic symbol of Paris.
