Argh! I'd worry about early senility if I couldn't remember making stupid
mistakes like that even when I was young.

So figure around 125 miles away, for a mile high Wall just visible from a
300 ft torturers' tower. I guess that's probably too far, so you'd probably
have to cut the down the Wall height even further.
