Eiffel Tower, wrought-iron tower in Paris, a landmark and an early example of wrought-iron construction on a gigantic scale. It was designed and built by the French civil engineer Alexandre-Gustave Eiffel for the Paris World's Fair of 1889. The tower, without its modern broadcasting antennas, is 300 m (984 ft) high. The lower section consists of four immense arched legs set on masonry piers. The legs curve inward until they unite in a single tapered tower. Platforms, each with an observation deck, are at three levels; on the first is also a restaurant. The tower, constructed of about 6300 metric tons (about 7000 tons) of iron, has stairs and elevators. A meteorological station, a radio communications station, and a television transmission antenna, as well as a suite of rooms that were used by Eiffel, are located near the top of the tower. |
