ESA's Proba satellite here shows a winding segment of the 7240-km long Great Wall of China situated just northeast of Beijing. The Great Wall's relative visibility or otherwise from orbit has inspired much recent debate.
The 21 hours spent in space last October by Yang Liwei - China's first ever space traveller - were a proud achievement for his nation. The only disappointment came as Liwei informed his countrymen he had not spotted their single greatest national symbol from orbit.

What is for sure is that what the human eye may not be able to see, satellites certainly can. Proba's High Resolution Camera (HRC) acquired this image of the Wall from 600 km away in space. The HRC is a black and white camera that incorporates a miniature Cassegrain telescope, giving it far superior spatial resolution to the human eye.

They were up to 25 feet (7.6 meters) high, 15 to 30 feet (4.6 to 9.1 meters) wide at the base, and from 9 to 12 feet (2.7 to 3.7 meters) wide at the top (wide enough for marching troops or wagons). At regular intervals, guard stations and watch towers were established.

Why Geat Wall was Built?
The Great Wall was key to protecting agriculture and resisting cavalry of the Huns and other warrior tribes from the north. The advantages of the enormous barrier diminished with the advancement of gunpowder and other weaponry.
The wall was originally built of stone, wood, grass and earth. In the Ming Dynasty bricks were produced in kilns set up along the wall. The bricks were transported by men carrying them on their backs, donkeys, mules and even goats had a brick tied to their head before being driven up a mountain.

Best time to visit the Great Wall
The Great Wall offers a timeless charm to tourists, but scenery varies with seasons. Visit it in different time you will get a quite different scene. In spring, when trees and plants begin to turn green, the wall wonders among the lush vegetation. Every thing looks so fresh. It is a good time to avoid the crowd tourists in summer and autumn.
