I believe so...I've just checked on Google Earth, and they have a similar thread. As they say, it's only a few metres wide and so difficult to resolve with the human eye. Look at it the other way - what can you see on the moon?
"In Earth's orbit at a height of 160 to 320 kilometers [100-200 miles], the Great Wall of China is indeed visible to the naked eye," says astronaut Eugene Cernan.A low angle of sunlight casting long shadows can help."You can see the Great Wall," confirms astronaut Ed Lu, who was the science officer of Expedition Seven on the International Space Station. The station circles Earth higher than Yang Liwei's orbit.The misconception is wrapped up in broader myths about what is and what is not visible from space. For the record: No manmade structures on Earth can be seen with the unaided astronaut's eye from the Moon. But many things -- highways, dams and even large vehicles -- are easily spotted from Earth-orbit with no optical aids.
For some reason, some urban legends tend to get stated and never disappear. This legend even appears as a erroneous Trivial Pursuit question. The legend? Many are familiar with the claim that the Great Wall of China is the only man-made object visible from space or from the moon with the naked eye. This is simply not true.The myth of being able to see the Great Wall from space originated in Richard Halliburton's 1938 (long before humans saw the earth from space) book Second Book of Marvels said that the Great Wall of China is the only man-made object visible from the moon.From a low orbit of the earth, many artificial objects are visible on the earth, such as highways, ships in the sea, railroads, cities, fields of crops, and even some individual buildings. While at a low orbit, the Great Wall of China can certainly be seen from space but it is not unique in that regard.However, when leaving the earth's orbit and acquiring an altitude of more than a few thousand miles, no man-made objects are visible at all. NASA says, "The Great Wall can barely be seen from the Shuttle, so it would not be possible to see it from the Moon with the naked eye." Thus, it'd be tough to spot the Great Wall of China or any other object from the moon. Furthermore, from the moon, even the continents are barely visible.
