The Great Wall of China, known to the Chinese as The Long Wall of 10,000 Li (Pinyin: Wànlǐ Chángchéng) is emblematic of China. This UNESCO World Heritage Site has a history which dates back over 2500 years. It is now a major tourist attraction in China with sections of the wall being restored for this purpose - especially near Beijing. The total length of the wall is unknown. Its size, age, complexity and general state of disrepair mean that new sections of wall are still being identified and some sections my yet await discovery. In its last incarnation, during the Ming Dynasty, the wall reached its zenith in building quality and length measuring 5,650 km and crossing 17 provinces in North and Central China.
