Of course, apart from the universe itself, there is a super-cluster of galaxies with hundreds of thousands of galaxies, each trapped by the gravitational effect of the whole. Our own "Local Group" of galaxies consists of only about 10 or 20 (?) galaxies.

The Universe.

The whole universe? There appears to be some sort of filimentary structure to the universe. Try looking up 'superclusters of galaxies' or the 'Harvard stick man'.
And that thing about the great wall isn't true. From space (not near-earth orbit), you can't make out any man-made structures on the earth. From near-earth orbit, you can make out several, not limited to the great wall.

I'm not sure what category: natural or man-made?
I have read that the Great Wall of China is the only man-made structure visible from space.

man made structure?
obsevered from space? during construction? personally?
my first guess would be the great wall of China
However some natural stuctures of various planets may be bigger.
