7. There Are Names on the Eiffel Tower
Thanks to restoration on the Eiffel Tower, the engraved names of 72 French scientists and engineers from the original design are visible again. Most of the scientists were active during the French Revolution and the early 19th century. The engravings were covered over in the early 20th century and restored for the first time in 1986-1987, and again last in 2010. More details here.
