The Eiffel Tower is a wrought-iorn skeleton in the Champ De Mars in Paris. Alexander Gustave Eiffel designed the tower for the world fair of 1889.
Elevators lead to the top.
The tower has a weather station and an area for experiments. For a while the tower was the biggest in the world. The tower helped with the Paris explosion of 1889. Not all people were happy with the tower. They thought it would fall because of all the weight.
