Statistics
The world's longest man-made structure, the 15- to 30-foot-tall Great Wall stretches approximately 4,000 miles from Shanhaiguan, China, in the east to Lop Nur in the west.
History
The first major wall was constructed during the reign of the First Emperor of the Qin dynasty in 208 B.C. Three subsequent walls were built between then and 1620 A.D.
Purpose
The wall was built to prevent foreigners from crossing the country's northern borders on horseback or easily return to their homelands with stolen property.
Tourism
Sections of the Great Wall sometimes can be packed with tourists. Summer and fall are its most popular tourist seasons. In winter the Wall is the least crowded, and the snow-covered mountains offer a stunning backdrop.
Myth
A 1932 "Ripley's Believe It or Not!" cartoon stated that the Great Wall of China is visible from the moon, and some textbooks have printed this as well. This "fact" is merely an urban legend.
