Eiffel Tower

The Eiffel Tower was designed by French engineer Gustave Eiffel and built by his company Eiffel et Compagnie for the 1889 Paris World's Fair. It was an ambitious project that took approximately two years and two months to complete.

Construction of the Eiffel Tower began on January 28, 1887, and was completed on March 15, 1889. It was a technological challenge for its time, as it became the tallest structure in the world at that moment. The tower is primarily made of wrought iron and was built using innovative methods and techniques.

The construction process involved the use of deep foundations to provide a solid base for the tower. Deep pits were excavated and filled with concrete to create the foundations. Then, four cast iron pillars were built rising from the foundations and joined at the top by iron beams.

The structure of the Eiffel Tower is divided into three levels. Each level was built separately and then assembled in its final place. Cranes and scaffolding were used to lift and join the different parts of the tower. The riveting technique was widely used to join the iron pieces, where the rivets were heated and placed in pre-drilled holes, then hammered to secure the connections.

The Eiffel Tower reaches a height of 324 meters, including the broadcasting antenna at the top. Originally, the tower was criticized by some as an ugly and unconventional structure, but over time it has become an iconic symbol of Paris and one of the most recognized monuments in the world.

The construction of the Eiffel Tower was an impressive achievement in terms of engineering and design, and it remains an important tourist attraction today.
