That is interesting. It is such an iconic landmark. I heard that there are elevators in the base to go up the tower.

Thank goodness there are elevators, otherwise we would have to walk so many stairs to get to the top of tall buildings!

Similar to the elevator is an escalator.is a type of vertical transportation in the form of a moving staircase which carries people between floors.
