The Great Wall of China was built in different historical periods. The exact length of the Great Wall of China as was constructed during the Ming Dynasty (1368 AD - 1644 AD) was determined to be 8,851.8 km in December 2008, as announced by a national survey team.

According to some sources and source maps (Lonely Planet, 8th Edition (2002), Lonely Planet Publications Pty Sydney, Australia) an outer defensive layer of the Great Wall of China extends through Hebei Province above Zhangjiakou and just South of Kangbao Town, to continue through Inner-Mongolia Autonomous Region and ends somewhere at quite a distance North-East of Hohhot in the Gobi Desert. The exact location and pathway of this Great Wall of China layer in Inner Mongolia is under research by China Report Staff (March 2009 AD). So far it is established that the eastern most section of this length of Great Wall starts somewhere near or at the Shandian River in Inner Mongolia AR, which lies just across the Northern-Central Border of Hebei Province. From there it passes around and south of Baochang Town. Due South-East of lies Paotai Yingzi, at the foothills of the Damagun Shan Mountain and the location of another visible and visitable Great Wall location (China Report is trying to confirm the existence of this location + coordinates via Google Maps and other sources).
As recently as 1998 AD archaeologists working in Xinjiang-Uygur Autonomous Region found a wall that ran from Yumen Pass (Jade Gate) near Dunhuang in Gansu to the northern edge of Lop Nur, skirting one of the trajectories of the Silk Road. As with other sections of the Great Wall in the far west including the Yumen Wall remnants, these were earthen ramparts made of rammed yellow sandy soil and jarrah branches. There is little or no doubt that this is part of the Great Wall - most likely dating to the Han Dynasty Era (206 BC - 220 AD), as it comprises a complete defensive network encompassing the flowbed of the Shule River with within the Oasis that served as the water sources for Han Chinese Military encampments which are known to have existed at this early time in this particular sector. This new discovery was dubbed Han Changcheng (Han Dynasty Great Wall) and it extended the length of the Great Wall by 500 km, to bring the wall to a length of 7,200 kilometers.
