One obstacle with the "several leagues" description is that that would 
make the wall at *least* 4.5 miles high. That's the height of the 
Himalayas -- not Everest but the higher peaks in the range. Meanwhile, I 
think it is safe to presume that the citadel is not far above sea-level.

Someone recently mentioned this quote by Severian:

"No. I've spent my life so near the middle of the city that the Wall was 
no more than a dark line on the northern horizon when we looked from the 
glass-roofed room at the top of our tower. I am astounded, I admit." 
SHADOW XXXV

What would the radius of the city need to be for a wall of that height 
to disappear beyond the horizon at ground level?
