Eiffel Tower, French Tour Eiffel, Paris landmark and technical masterpiece of architectural history. When the French government organized the Universal Exposition of 1889 to celebrate his centenary of the French Revolution, a competition was held to design a suitable monument.
Among his more than 100 proposals by the world's great architects, the French government chose Gustave, a French engineer best known for his contributions to the construction of metal bridges and the design of the Statue of Liberty, to his We chose the Eiffel proposal.
His proposal won for its originality and technical aspects. Assembly required 18,038 pieces of iron and 2.5 million rivets.
Aside from the controversies, associated work, and structural intricacies, the history of the Eiffel Tower is full of legends and curiosities. Among other things, this includes height variability. The tower itself is 300 meters high. It sits on a 5-meter (17-foot) high base, and the tower's television antennas bring its total height to 324 meters (1,063 feet).
The thermal expansion of the metal that occurs in the summer causes the tower to elongate an average of 15 cm during the hottest months. The largest growth on record occurred in 1976, when this heat-related expansion increased the tower's height by another 18 centimeters (7 inches) to 324 meters.
Another interesting element associated with this beautiful monument is its repainting, which takes place on average every seven years. The tower's color has changed several times, from Venetian red to ocher yellow, maroon, and finally to the current bronze, chosen in 1968.
