Eiffel TowerAnother undisputed great engineering feat is the Eiffel Tower, a huge wrought-iron skeleton in Paris. Alexandre Gustave Eiffel designed the 984-foot tower for the exposition of 1889. The Eiffel Tower contains about 7,000 short tons of iron and steel and cost more than $1 million. For many years, it was the highest structure in the world and served as an important military observation station during World War I. Since 1953 it has been used to transmit television programs.
