It may come as a surprise that at the most recognizable monument in Paris, there are Untapped things to do. But the Eiffel Tower is actually full of amazing little finds if you look closely enough.
Like many architectural gems built for World’s Fairs, the Eiffel Tower wasn’t intended to be a permanent structure. A plaque in the military bunker states that since Eiffel knew he needed to attach functional uses to the tower, he allowed it to be used for many experimental, scientific purposes. Wireless transmission turned out to be the key, and the Eiffel Tower became the site of the first radiotelegraph broadcasts.
