Is the Great Wall of China really visible from space?

We often hear that the Great Wall of China is the only man-made structure that is visible to the naked eye from space. Well not really! It's actually a myth based on that 18th century and was launched by the English antiquarian William Stukeley who wrote: “Hadrian's Wall is only surpassed by the Great Wall of China, which is a huge figure on top of it globedraws and could be clearly visible from the moon ”. This idea was picked up later in the 19th century.

In reality it is Great Wall of China about 6,700 km long, but not more than 6 m wide, which is several dozen or hundreds in height kilometre above the ground, making it difficult to identify.
