Eiffel Tower Saved by Radio

Paris, France’s Eiffel Tower was built for the 1889 Paris Centenniel Exposition, but was destined to only stand 21 years. Artists and other critics who called it a giant lamppost wanted it demolished immediately despite its popularity with visitors. However, in 1907 it was found to be an excellent transmitter of radio waves, which even reached America. It's functionality as a giant antenna saved the tower.
