The Eiffel Tower is a wrought-iron lattice tower in Paris, France, standing 330 meters (1,083 feet) tall. It was designed and built by engineer Gustave Eiffel's company from 1887 to 1889 for the 1889 World's Fair, celebrating the centennial of the French Revolution. It was the tallest man-made structure in the world for 41 years until 1930. The tower is the most visited paid monument worldwide, with millions of visitors each year. The tower has three public levels with restaurants on the first two floors and an observation deck at the top. Visitors can ascend by stairs or elevator, though the top is usually accessed by elevator. It was initially controversial but has become a global cultural icon representing Paris and France. The tower also played roles in history, such as during World War I for intercepting enemy radio communications. It stands on four lattice-girder piers forming a square base 125 meters wide and includes a private apartment at the top used by Eiffel. The tower is notable for its architectural and engineering significance and offers stunning panoramic views of Paris, best seen early morning or at dusk.
