THE GREAT WELL OF CHINA

The Great Well of China is the largest defence fortification. It is about 1500 miles long, this unique wall stretches from the Gulf of Cicily of the yellow sea along the northern frontier of China to kansu Province in the west. It is the only structure on earth that can be identified from the moon. In the 3rd century BC it was linked up. It is made of rubble, tamped earth and brick. Later it was modified, repaired and extended several. It was built to defend China from enemies. The wall was so constructed in such a way that troops summoned by beacon fire could be quickly transported along its top.
