Great Wall of China...

Great Wall of China...

Construction of the Great Wall began in the 7th century BC and continued for hundreds of years. It's the longest fortification ever built, constructed to thwart invasions of Mongolian and Manchu enemies. At its height (well, length), it was more than 3700 miles (6000km) long.
