1889 | Eiffel Tower opens
The Eiffel Tower is 984 feet tall and consists of an iron framework supported on four masonry piers, from which rise four columns that unite to form a single vertical tower. Platforms, each with an observation deck, are at three levels. Elevators ascend the piers on a curve, and Eiffel contracted the Otis Elevator Company of the United States to design the tower’s famous glass-cage elevators.
The elevators were not completed by March 31, 1889, however, so Gustave Eiffel ascended the tower’s stairs with a few hardy companions and raised an enormous French tricolor on the structure’s flagpole. Fireworks were then set off from the second platform. Eiffel and his party descended, and the architect addressed the guests and about 200 workers. In early May, the Paris International Exposition opened, and the tower served as the entrance gateway to the giant fair.
The Eiffel Tower remained the world’s tallest man-made structure until the completion of the Chrysler Building in New York in 1930. Incredibly, the Eiffel Tower was almost demolished when the International Exposition’s 20-year lease on the land expired in 1909, but its value as an antenna for radio transmission saved it. It remains largely unchanged today and is one of the world’s premier tourist attractions.
