What happened
Though wall-building along China's northern frontier began under Qin Shi Huang in the 3rd century BCE, the fortification visible today is almost entirely the work of the Ming dynasty, which rebuilt and extended the line using brick and stone rather than the rammed earth earlier dynasties had relied on. Most of this reconstruction took place between roughly 1560 and 1640, spanning the reign of the Wanli Emperor (1572-1620), and added the distinctive watchtowers that mark the wall's present appearance. Bricks let builders work more quickly on rough terrain than earlier rammed-earth methods allowed, and the Ming extended the wall's line through difficult mountainous stretches that earlier dynasties had left unfortified.
Why it matters
The Great Wall people visit and photograph today is fundamentally a 16th and 17th century Ming structure responding to renewed threats from the north, not the original Qin-era fortification, which has largely eroded away as rammed earth. UNESCO recognized the wall as a World Heritage Site in 1987, citing Ming-era construction as the point when it became the world's largest military structure.
How we know
Archaeological surveys of the wall's construction materials and inscriptions distinguish Ming brick-and-stone sections from earlier rammed-earth sections, and Ming court records document the building campaigns under commanders such as Qi Jiguang.
