Standing over 300 metres tall (324 if you include the antenna spire), (984ft, 1062ft) the Eiffel Tower is one of the most impressive man-made structures ever built. It was selected from 107 different projects as part of a competition for the 1889 World’s Fair in Paris, which celebrated the 100th anniversary of the French Revolution. The idea of the Eiffel Tower was proposed by entrepreneur Gustave Eiffel, engineers Maurice Koechlin and Emile Nouguier, and an architect called Stephen Sauvestre.

First digging work of the Eiffel Tower began on 28th January 1887 and the entire structure was completed on 31st March 1889.Taking only just over 2 years to construct such an awesome monument was an amazing achievement, even by modern construction standards. You can see how it developed over time in the picture below:

The tower is made entirely of iron (over 7,000 tonnes in total!), which Gustave Eiffel selected as it was cheaper to use than steel at the time. It’s held together by a whopping 2.5 million rivets and even though iron was cheaper than steel, it cost almost 8 million French Gold Francs to build!

Take a look at the video to learn more about the way the tower was built.
