It's been a year now from my last travel to Madrid(Spain)... We were at a hotel "Puerta América" ( More info) which has an amazing and scaring outer cristal corridor at the top.
I wasn't able to go further over It but I think you can get the idea looking at my shot

View from the outside...if you think it's not high enough, go check It out 😅
