Eiffel Tower constructed

Engineer Gustave Eiffel designed and built the 300-meter open-lattice wrought-iron tower for the 1889 Exposition Universelle in Paris, commemorating the centennial of the French Revolution. Construction took two years, two months, and five days, using more than 18,000 iron pieces and 2.5 million rivets with no worker fatalities. The completed structure stood as the tallest in the world until the Chrysler Building surpassed it in 1929. Two million visitors ascended the tower during the 1889 fair.
