And stone? I've seen buildings made out of stone, but this much stone? How did they mine it? There must be so many stairs. That wouldn't be a problem for me but I can't imagine how they get to the top. I'll look forward to night-time now, though. The view from the top must be something.
And yes, I know exactly what you mean and the air and space. I miss the sky, there's so little of it available with all the buildings in the way.
