Eiffel Tower

Eiffel Tower, structure designed by A. G. Eiffel and erected in the Champ-de-Mars for the Paris exposition of 1889. The tower is 984 ft (300 m) high and consists of an iron framework supported on four masonry piers, from which rise four columns uniting to form one shaft. Three platforms at different heights (the intermediate platform just above the junction of the columns is 644 ft/196 m high) are reached by stairs and elevators. On the top of the tower are a meteorological station, a wireless station, and a television transmission antenna.

Parisian landmark built for the Centennial Exposition of 1889. Conceived by the bridge engineer Gustave Eiffel (1832–1923), the 984-ft (300-m) tower of open-lattice wrought iron was a technological masterpiece. Making use of advanced knowledge of the behaviour of metal arch and truss forms under loading, the structure presaged a revolution in civil engineering and architectural design. The tower was the world's tallest building until the Chrysler Building in New York City was topped off in 1929.
