Descrizione:

Spanning the vast majority of north China, the Great Wall was a large fortification built mainly during the Ming rule, although the early precedents of construction were as far back as 200 B.C. Hundreds of thousands of laborers over a period of many years worked on the wall in order to keep the Mongols out.
