The document provides details about the Eiffel Tower, including its construction from 1887-1889. It was built by Gustave Eiffel and his team as the centerpiece of the 1889 World's Fair. Over 18,000 pieces of puddled iron were assembled using 2.5 million rivets to construct the 324 meter tower. The innovative design and rapid construction were engineering feats that cemented the tower as a global icon of structural design.
