Depends on how far away you are -- from low Earth orbit, lots of man-made objects are visible to the naked eye. From the moon, no man-made objects are discernable by the naked eye.

Depends on where "from" is measured. From the Moon, nothing manmade can be seen with the naked eye, except for maybe lights of a large city . From Earth orbit, city lights are still about it.
The Great Wall is all but invisible, see Google Earth or Virtual Earth:

The Great wall is swamped by Beijng, rivers, mountains, etc..
Bear in mind that the Great Wall is only about 10 meters across, which is narrower than most freeways in the US.

None can be seen from Earth orbit (about out where the shuttles go). Not even the great wall - it's a myth. Check out www.badastronomy.com for more info, or www.snopes. com, or www.thestraightdope.com .
