Is the Great Wall of China visible from space with the naked eye?
No — the evidence does not support this claim.
The Great Wall of China is visible from space with the naked eye.
What the evidence shows
The Great Wall is generally not visible to the unaided human eye from low Earth orbit, and certainly not from the Moon. Although it is long, it is only a few meters wide and blends in color with the surrounding land. Astronauts, including China's first astronaut, have reported being unable to see it without aid.
