Keep Eiffel Tower as it is. Interesting: in Germany n some TV towers observation decks were closed, while tourists have to wait obviously for several hours to visit Eiffel Tower. And for those who want to get up a lattice tower I recommend the old Berlin Radio Tower. And for those who have no problems with long stairways visit Torre Faro (
