The Eiffel Tower was constructed between 1887 and 1889 as the entrance to the 1889 World's Fair in Paris, France. It is over 1,000 feet tall and made of over 7,000 tons of iron. Originally intended to only stand for 20 years, the tower became a symbol of Paris and is one of the most recognized structures in Europe, attracting over 200 million visitors since its opening.
