The Eiffel Tower, standing tall at 324 meters, was built for the 1889 World's Fair. It was originally intended to be a temporary structure, but the French were so enamored with their metal behemoth that they decided to leave it standing.
Designed by Gustave Eiffel, the tower took over two years to complete. It was meant to be a symbol of French engineering prowess, but some say it was just a really tall metal stick with a bunch of stairs.
Today, the Eiffel Tower is one of the most visited sites in the world. It's a must-see for any tourist looking for a good Instagram opportunity.
