Gustave Eiffel was the main architect behind the design of the Eiffel Tower, although it was also the engineering genius of Maurice Koechlin and Émile Nouguier that contributed significantly to its groundbreaking design. Completed in 1889 for the Exposition Universelle in Paris, the Eiffel Tower was initially met with criticism but has since become an iconic symbol of architecture and engineering. Its iron lattice structure showcased the possibilities of modern materials and design, influencing future architectural projects worldwide. The tower not only serves as a tourist attraction but also represents France’s industrial prowess during the late 19th century.
