The Eiffel Tower is a wrought-iron lattice tower in Paris, designed by engineer Gustave Eiffel and constructed from 1887 to 1889 as the entrance gateway for the 1889 World's Fair celebrating the centenary of the French Revolution. It stands approximately 330 meters (1,083 feet) tall including its antenna, was the tallest man-made structure for 41 years, and is one of the most popular paid tourist attractions in the world with about seven million visitors annually.
Key Facts About the Eiffel Tower
- Design and Construction : It was designed by Gustave Eiffel and his company, with a team of about 50 engineers and architects and 500 workers contributing to the build. The tower was completed in just over two years without reported injuries, using around 18,000 metal parts held with 2.5 million rivets.
- Height and Structure : The tower is 300 meters high at the top of its structure, with a base of 5 meters tall and antenna adding to 330 meters total height. It was the first structure to surpass both 200 and 300 meters in height. It weighs about 10,100 tons and comprises lattice-girder piers that taper inward, linked by viewing platforms.
- Changes and Usage : Initially criticized for its design, the Eiffel Tower was saved from dismantling by its usefulness for telegraphy and meteorology. It hosted meteorological stations, military telegraphs, aerodynamic laboratories, and later, TV and radio antennas which increased its height.
- Tourism and Cultural Impact : It has multiple levels for visitors with restaurants, shops, and observation decks—the highest public deck is 276 meters above ground. The tower inspired artists and continues to be a symbol of Paris and modern engineering. It is repainted every seven years to protect the ironwork.
- Other Trivia : The tower sways slightly in high winds and can grow or shrink by about 15 cm depending on temperature. It offers expansive views of Paris, and it was once home to a small post office and Gustave Eiffel’s apartment.
