The Great Wall of China is a series of stone and earthen fortification built over a millennium. Despite popular belief, the wall was not originally constructed to protect against Mongol invaders, but instead built by the various Chinese states to protect their own borders against each other during the Warring State Period in 5th century BC. Most of the original walls was destroyed after Qin conquered all opposing sates and unified the country. The remaining wall was extended into a new northern wall which would protect against the empire against the nomadic Mongols from the north.
The first walls were simple walls made up of rammed earth and stones. By the Ming dynasty in the 16th century more advance techniques were used on the rebuild the walls, bricks, tiles and cut stones.
The MOC depicts the great wall in later age as a young Emperor watches his army march to battle.
