Eiffel Tower, a wrought-iron skeleton structure on the Champs de Mars, a former parade ground in Paris, France. It is often considered to be the symbol of Paris. The tower itself is 984 feet (300 m) high; a television antenna, installed in 1957, added about 67 feet (20 m). Until the Empire State Building in New York City was completed in 1931, the Eiffel Tower was the world's tallest structure.

The tower rests on four masonry piers. An arched and latticed column rises from each pier. The columns meet about 620 feet (189 m) above the ground to form a single shaft. There are observation platforms at the 187–foot, 377–foot, and 899–foot (57–m, 115–;m, and 274–m) levels. Stairways and elevators are used to reach the platforms, which give breathtaking views of Paris. Restaurants, shops, a theater, and meeting rooms are on the first two levels.

The tower was completed for the Paris Exposition of 1889. It was designed by Alexandre Gustave Eiffel (1832–1923), a French engineer, who also designed the dome of the Nice observatory and the framework of the Statue of Liberty. The first year's admissions nearly paid the construction cost of more than $1,000,000. The tower was completely renovated in 1982–83.
