First Eiffel Tower Sketch
This is the first sketch of the Eiffel Tower before it was built in Paris, France. At the time, the project’s working title was “Pylone de 300 mètres de hauteur,” which loosely translates to pylon with a height of 300 meters. And although Eiffel had the naming rights, it was Maurice Koechlin and Emilie Nouguier who reportedly drew the tower’s original design along with Stephen Sauvestre, a French architect. Another fun fact is that it took 300 steelworkers two years, two months and five days to complete the tower.
