when the eiffel tower was built
Quick Answer. The Eiffel Tower was built to serve as a gateway into the World's Fair held in Paris in 1889. Initially only built as a temporary structure, meant to last less than 20 years, it has since become one of the world's architectural wonders. It is rigorously maintained for safety and to preserve the integrity of the structure.
The Eiffel Tower is not just a monument to aerodynamics and aesthetics, it is a model of organization and management. Completed in just two years, two months and five days, the project finished ahead of schedule. Slated to open on May 6, 1889, the Eiffel Tower was ready on March 30 of that year.
