Like the Berlin Wall of fond memory, the Great Wall of China has spent the better part of its existence as something like a rumour.
China was so inaccessible for so long, the wall took on the patina of myth. Among Westerners, it had only been seen by the lucky few and as a result, like Stephen King’s monster in the closet, it became an almost supernatural thing, so when China started opening up, which is still not so very long ago, the Great Wall of China shot to the top of everyone’s list of things that must be seen.
