The claim that China's Great Wall is the only man-made object that can be seen from the moon with the naked eye is one of our more tenaciously incorrect \"facts,\" a bit of erroneous speculation which was spawned decades before we had the means to demonstrate it true, and which continues to have currency despite having long since been proved false. Some less specific versions of the Great Wall claim maintain it is the only man-made object that can be seen from \"space,\" but although the term \"space\" is rather non-specific, it is not difficult to show the Great Wall claim to be false for any reasonable definition of the term.

According to Snopes, visual images of the wall are totally dependant on the height at which you try to view it. Visual recognition starts to diminish at 150 miles.
