The Great Wall of Gansu, China: A Thousand-Year-Old Pass on the Ancient Silk Road

The Great Wall of Gansu, which stretches across the Hexi Corridor, was a military barrier and transportation throat for the ancient Central Plains Dynasty to explore the Western Regions, and is mainly composed of the remains of the Great Wall of the Han and Ming Dynasties. The Great Wall of the Han Dynasty was built mainly of rammed earth, with Yumen Pass, Yang Pass and other passes along the route, witnessing the prosperity of the Silk Road; the Great Wall of the Ming Dynasty was built mostly of masonry, with Jiayuguan Pass, the "most powerful pass in the world," as the core node, with well-preserved citadels, piers and beacon flints. As an important part of the Great Wall of China, the Great Wall of Gansu not only embodies the wisdom of the ancient military defense system, but also carries the historical memory of the intermingling of civilizations between the Central Plains and the Western Regions, which was included in the World Cultural Heritage List in 1987, and has become an important physical testimony for the study of ancient border culture and the history of the Silk Road.
