About
Established in the Western Han Dynasty, it paired with Yangguan as the two vital frontier passes controlling the northern Silk Road route, named for jade transported from the Western Regions through this checkpoint. Immortalized by the famous line Beyond Yumen Pass no warm spring breeze can reach, the scenic area is a heritage cluster covering three sites: the Small Square City (the main Yumen Pass ruin rammed with loess), the ruins of the Han Dynasty Great Wall, and Hecang City (ancient military granary). It is a fixed stop on Dunhuang’s classic west line one-day tour together with Yangguan and Yardang Geopark.
