This tower is over 1000 feet tall and was built in the middle of Paris in just 2 years for the International Exposition of 1889.

It was designed by 2 people who worked with the famous engineer Gustave Eiffel.

The final shape of the Eiffel Tower was chosen by his architect.

But how did they manage to build the highest tower in the world at the time?

The genius idea was to imagine a tower made of iron that was solid but lighter than stone.
