Oh, sorry, didn't the Eiffel tower had its safety bars and nets? Even through them it's still a little overwhelming though. Ah, yeah, a few times. But first time was the best. I had no experience with travelling, no money, lots of luggage, and I ended up in a very weird hostel with dark windows (found by chance). Another time was very close to getting robbed. There is something scary about Paris too, but I like that even more.
