Some investments only make sense after they find a second purpose.

On March 31, 1889, Gustave Eiffel officially inaugurated the Eiffel Tower as the centerpiece of the Paris Exposition Universelle. Built to showcase French engineering and attract visitors to the world’s fair, the tower was originally granted only a twenty-year concession before it was expected to be dismantled.

Many critics saw the towering iron structure as an eyesore. Artists and writers protested its construction, arguing that it would scar the Paris skyline. But the tower survived its planned expiration by discovering a new role.

Its height made it useful for early radio transmission experiments and later military communications. That unexpected second business model helped justify keeping the structure in place long after the exposition ended.

Over time, the Eiffel Tower evolved from temporary spectacle into one of the most recognizable and economically valuable landmarks in the world, attracting millions of visitors each year and generating tourism revenue that far exceeds its original purpose.
