History:

The history of the Great Wall of China has fascinated people from all parts of the globe. The monument is considered one of the marvels of the ancient world extending over rugged terrain along China's nothern border, constructed over many dynasties. The defensive barrier may have started as early as the Spring and Autumn period that lasted from 770 BC to 476 BC.

The purpose of the Great Wall is to deal with the threat of foreign invaders, the Chinese built stone and earth barries and fortifications. The wall had to be high enough to prevent riders on horseback from scaling the structure. Armed sentries and detachments patrolled the wall for signs of an impeding invasion.

If any build up of troops were detected, the Chinese would deploy their own forces along moving along the top of the wall itself or along associated roads. Successful defence relied on the ability of the government to respond quickly and in force to any possible threat along a vast defensive perimeter.
