1) Can't see it from orbit.___2) The 7 Wonders did not not include China.___3) But Jojo's right about the Internet. It should be on any modernized list.
ARGH! You can't see the Great Wall of China from the Moon. I challenge you to look at Earthrise (http://en.wikipedia.org/wiki/Earthrise) and tell me what CONTINENT is visible. You can't even see it from orbit. You can see the landing strip at Kennedy Space Center, because it is a white strip in the middle of the green nature preserve. You can't see the Great Wall of China because it is a dun colored object on a dun colored background.
When is this stupid legend going to die?
