The Ming Great Wall, 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.

The "Stairway to Heaven" stretch of the Simatai Great Wall runs through precipitous terrain. Reinforced after the raid of 1576 so as to "not let a single horse in" (匹馬不入), as noted by a Ming official.
The Great Wall of China is a series of fortifications that were built across the historical northern borders of ancient Chinese states and Imperial China as protection against various nomadic groups from the Eurasian Steppe. Several walls were built from as early as the 7th century BC, with selective stretches later joined by Qin Shi Huang (220–206 BC), the first emperor of China. Little of the Qin wall remains. Later on, many successive dynasties built and maintained multiple stretches of border walls. The best-known sections of the wall were built by the Ming dynasty (1368–1644).
