Great Wall Of China

The great wall of China is a place of defense for the borders
of the northern and northwestern parts of China. The wall runs
along the east to the area surrounding Goadai, Gansu Province.
On the west there is an inner wall running from the surrounding
area of Beijing almost to Hadan.
The largest portion of the wall was erected by Shih Huang Ti. He
was the first emperor of the Ch'in Dynasty. It was made for defense
against raids by nomadic people.
Work on the wall started about 221 B.C, after Shih Huang Ti had
united China. It was finished by about 204 B.C. Small sections of
the wall might have already existed, but Shih Huang Ti is supposed
to have had about 1900 km (about 1200 mi) of the wall erected
during his rein. In later centuries, especially during the period of
the Ming Dynasty (A.D 1368-1644), the Great Wall was repaired
and extended. The fortification finally reached a length of about
2400 km (1500 mi). It follows the courses of rivers instead of
bridging them. It conforms to the contours of the mountains and
valleys in its way.
The wall is built of earth and stone. There is brick on the east
side of the wall. It is from 4.6 to 9.1 m thick at the base and
tapers to about 7.6 m.
There is no wonder why I chose The Great Wall Of China as
my own wonder. Did you know that you can even see "The
Wall" from outer space?
