Eiffel Tower history : the beginning. The most popular tourist place in Paris has stretched to the Parisian skies for 127 years. Although now symbolic of France, it wasnât meant to last. Without a doubt, the turning point in the Eiffel Tower history took place at the 1889 Universal Exposition.
In France, the Eiffel Tower is known as La Tour Eiffel or la dame de fer, which means âthe iron lady.. It's an iron lattice tower that stands 984 feet tall (1,063 feet if you include the broadcast antennas at the top). At completion, it passed the Washington Monument as the tallest man-made structure in the world. It held that title until 1930, when the Chrysler Building was built in New York City. The Eiffel Tower remains the tallest building in Paris. It is also the most-visited paid monument in the world.
