Astronauts — including China's Yang Liwei — have said they couldn't see the Wall unaided from orbit. It's long but only ~5–10m wide and roughly the same color as the land around it; the eye resolves width, not length.

The kernel of truth: it CAN show up in low-orbit photos with a zoom lens, and airports/cities are far more visible. But 'visible to the naked eye from space,' as the claim is usually told, is false.
