Why did they build the Eiffel Tower? At 1,063′ tall the Eiffel Tower was the tallest structure in the world until 1930 and is now the most visited paid monument in the world. It survived two world wars. It survived a destruction order from Hitler after the French cut the lift cables to deny him access. It survived a secret order from French President Charles de Gaulle to be deconstructed and moved to Montreal. Built in 1889 under much protest, it stands today as the most recognized structure in the world. The Eiffel Tower was built for one purpose, brilliant marketing, period.
