How come the Great Wall of China was built?

The Great Wall originally existed as segments of walls between

rival factions. When these were united around 221 BC (by emperor

Qin Shi Huang), the wall was joined, lengthened, and fortified to

keep out invaders from the north of China.

There are small forts at intervals that could be used for

defensive forces, and ramparts and turrets from which weapons could

be fired.
