The two pictorial charts illustrate the Eiffel Tower in Paris and the outlined project for its underground extension.
The Eiffel Tower is located on the banks of the Seine River and right next to the Ecole Militaire in Paris. Five levels will be developed underneath the structure per the outlined project. Starting from the bottom two levels (fourth and fifth), visitors would park their vehicles and use the two vertical lifts to access all other floors. The third level will contain a cinema and museum for entertainment. The second level will include multiple shops and restaurants. Finally, the top-level will house the ticket office to grant access to the tower.
The structure spans 324m vertically and weighs 10,100 tonnes from the main level. The first viewing platform is at the height of 57m, and the next is 1665 steps above at 115m.
