The Ming Great Wall (明 長城; Ming changcheng), built by the Ming dynasty (1368 -- 1644), forms the most visible parts of the Great Wall of China today. A comprehensive archaeological survey, using advanced technologies, has concluded that the Ming walls measure 8,850 km (5,500 mi) from Jiayu Pass in the west to the sea in Shanhai Pass, then looping over to terminate in Manchuria at the Hushan Great Wall. This is made up of 6,259 km (3,889 mi) sections of actual wall, 359 km (223 mi) of trenches and 2,232 km (1,387 mi) of natural defensive barriers such as hills and rivers.
