What's tha Height and History of tha Eiffel Tower

The Eiffel Tower is a famous landmark in Paris and a technological marvel in the history of building construction. A competition for the creation of an appropriate monument was organized when the French government was planning the International Exposition of 1889 to commemorate the 100th anniversary of the French Revolution. Among the more than a hundred proposals that were submitted, the renowned bridge engineer Gustave Eiffel's was approved by the Centennial Committee. The idea of Eiffel, a 300-meter (984-foot) tower composed nearly entirely of wrought iron with open lattices, caused shock, skepticism, and not insignificant resistance on the grounds of aesthetics. After it was finished, the tower functioned as the exposition's entryway.

The Eiffel Tower was twice as tall as the Great Pyramid of Giza and the dome of St. Peter's in Rome, and nothing like it had ever been constructed. Unlike these older monuments, the tower was built at a minimal cost and in a few two years (1887–1889), using a tiny labor force. Utilizing his extensive understanding of how metal arch and metal truss forms behave under stress, Eiffel created a light-filled, airy, yet sturdy building that foreshadowed a revolution in architectural and civil engineering design. Furthermore, it ultimately proved to be visually correct after it was made publicly accessible on May 15, 1889.

Four lattice-girder piers support the Eiffel Tower; these piers taper inward and unite to form a single, massive vertical tower. The piers are joined to one another as they curve inward by networks of girders at two levels, which provide tourist observation platforms. The four semicircular arches at the base of the tower, on the other hand, are only decorative features with no structural significance. The piers' distinctive shape, which was influenced by both engineering and aesthetic sensibilities, meant that elevators had to ascend on a curve. The Otis Elevator Company of the United States designed the glass-cage machines, which became a key component of the building and contributed to its reputation as one of the most popular tourist destinations in the world.
