It was built along China's northern and western borders, to keep out invading Mongols. Originally it consisted of walls built between rival Chinese factions, but was lengthened and rebuilt several times over a period of 2000 years, until the end of the 16th century. The parts built in the mountains from durable stone still exist in several places, but much of the wall has crumbled into ruins.
