Ming Dynasty (1368-1644)

The Great Wall of the Ming Dynasty was initially constructed to defend against the Mongols, and later it served as a defense against the rise of the later Jin Dynasty. Ming Great Wall stands as the largest, strongest and most magnificent in history. Its main line extends from Hushan in Liaoning province in the east to Jiayuguan in Gansu province in the west. This period saw extensive engineering works and significant advancements in construction materials, techniques and defensive fortifications. Furthermore, the remains of the Ming Great Wall are the most completely preserved to date.
