The Great Wall
of China
What is the Great Wall?
The Great Wall of China is the
world’s largest military structure.
It was built as a defense to stop
invaders from northern areas.
Those “invaders” were mostly
from China’s neighbor to the
north, Mongolia.
The Great Wall is actually a
series of walls built and rebuilt
by different dynasties over
1,000 years.
The Great Wall has a total length of over 1500 miles.
A second wall, further south from the Great Wall measures about 342
miles long. What purpose do you think that wall served?

fell to peasant uprising.
