Eiffel’s concept of a 300-metre (984-foot) tower built almost entirely of open-lattice wrought iron aroused amazement, skepticism, and no little opposition on aesthetic grounds.

Following the establishment of a technological challenge that became possible with the advent of the Industrial Revolution, engineers from all countries had sought since the mid-nineteenth century to create a tower of 1000 feet high (about 300 meters). When the French government was organizing the International Exposition of 1889 to celebrate the centenary of the French Revolution, a competition was held for designs for a suitable monument. Because of their unique shape, which was dictated partly by engineering considerations but also partly by Eiffel’s artistic sense, the piers required elevators to ascend on a curve; the glass-cage machines designed by the Otis Elevator Company of the United States became one of the principal features of the building, helping establish it as one of the world’s premier tourist attractions.
