According to a plaque in the military bunker, "Gustave Eiffel knew that in order to survive, the Eiffel Tower would have to prove its practical worth for science. The tower was scheduled to be dismantled after just 20 years. [So] he...allowed it to be used for a wide range of scientific experiments, from meteorological and astronomical observations to monitoring physical and air resistance phenomena.
"He secured the future of his tower with the installation of a huge wireless transmission antenna." The tower then became the site of the first radiotelegraph broadcasts of the early 20th century, the plaque says.
