Most travelers know Dunhuang for the Mogao Caves and Mingsha Sand Dunes, but about 90 kilometers northwest of the city lies a completely different landscape—Yumen Pass and the Han Great Wall ruins. These sites once formed a crucial part of the Silk Road frontier defense system during the Han Dynasty. Today, only remnants of rammed-earth walls and desert ruins remain, yet standing here still evokes the movement of ancient caravans and the life of border soldiers guarding the western frontier.
Yumen Pass Ruins – a Key Pass on the Han Dynasty Silk Road
Small Square City – Core Ruins of Yumen Pass
Small Square City is the commonly referred Yumen Pass ruins, a square earthen castle standing alone in the gobi desert. Built of rammed loess, it has weathered two thousand years of wind and rain, with some walls collapsed, but the overall outline is clear. The castle is about 20 meters long on each side, and the highest existing part is about 10 meters, showing the military garrison layout of that year. In the 1940s, bamboo slips inscribed with “Yumen Commandant”were unearthed here, confirming that this was the location of Yumen Pass in the han dynasty (it was moved east to Guazhou after the tang dynasty). There are wooden plank roads around the castle, allowing you to walk around and view it from different angles. The visit takes about 20-30 minutes. If the weather is clear, you can overlook the snow-capped peaks of the qilian mountains. The interior of the castle is not open to the public.
Visiting Highlights:
- Rammed earth city walls: a physical witness to the construction technology 2,000 years ago
- Origin of Yumen Pass’s name: jade from the western regions was imported into the central plains through this pass
- The desolate mood of “spring breeze never blows here”: perfect for taking photos

Large Square City – Han Dynasty Granary Ruins
About 10 kilometers northeast of Yumen Pass is Large Square City, also known as Hecang City. It is much larger than Small Square City, rectangular in shape, about 130 meters long from east to west and 15 meters wide from north to south, and was the granary for the border garrison troops in the han dynasty. The walls retain traces of warehouse partitions and ventilation holes. It was built beside the old course of the shule river, and grain was transported to the granary via the river in those years. Today the riverbed is dry, and the surrounding saline-alkali land is desolate and silent. Standing in front of the city, you can imagine the scene of sufficient grain and grass and stationed troops in ancient times. Compared with Small Square City, there are fewer tourists here and the atmosphere is stronger. The visit takes about 20-30 minutes.

Han Great Wall Ruins – Border Defense Great Wall of the Han Dynasty
History and Construction Technology of the Han Great Wall
The Han Great Wall in the Yumen Pass scenic area is part of the han dynasty great wall. Built by the han dynasty to defend against the xiongnu, it stretches more than 1,000 kilometers from Yongdeng in Gansu in the east to Lop Nur in Xinjiang in the west. The section at Yumen Pass is well preserved and is the best-preserved section of the han dynasty great wall in china. The section near Danggu Sui is particularly intact, 2.95 meters high, 3 meters wide at the base, 0.65 meters wide at the top, and about 300 meters long. The construction method is unique: craftsmen used local materials, alternating rammed layers of red willow, reed, poplar branches and sand and gravel – first laying a layer of plant stems, then covering with sand and gravel, and pouring alkaline water to condense them, stacking layer upon layer. This “reed wall”seems simple but extremely strong. Plant fibers act as natural “steel bars”, and alkaline water serves as a coagulant. Looking closely at the wall section, you can clearly see the layers of reed and loess, and the reeds have not completely rotted to this day.
Three Major Highlights:
- Reed interlayer structure: clear layers visible on the wall section, not rotted for 2,000 years
- Wisdom of adapting to local conditions: a model of using local materials in the gobi environment
- Well-preserved section at Danggu Sui: 5 kilometers west of Yumen Pass, the great wall is particularly well preserved
Firewood and Beacon Towers – Han Dynasty Alarm System
Along the great wall, there are “one large tower every ten li, one small tower every five li”. These yellowish square platforms are beacon towers. Garrison soldiers kept watch day and night. In case of enemy situation, they “lit torches and burned firewood”- smoking during the day and lighting fires at night, transmitting alarms layer by layer through beacon fires. Near Danggu Sui, 15 piles of “firewood”used for alarm are still preserved. The largest one is more than 2 meters long and 1.3 meters high, bound with reeds crisscross, and has condensed into fossils. This alarm method could transmit messages thousands of li a day. It took about two to three days to travel more than 4,000 li from Dunhuang to Chang’an. These firewood piles witnessed the daily life of border garrison soldiers – they not only watched for beacon fires, but also repaired cities and fortifications, dug canals and farmed, raised horses and wove shoes.

Practical Tips for Visiting Yumen Pass and Han Great Wall
Prepare for Sun and Sand Protection
There is no shade in the gobi desert, and the uv index is always 8-10 (extremely strong) all year round. The following is a list of essential items:
- Sun protection equipment: wide-brimmed sun hat, sunglasses, long-sleeved sun protection clothing, spf50+ sunscreen (reapply every 2 hours)

- Clothing choice: recommended “onion-style”dressing – quick-drying breathable long sleeves + detachable fleece jacket to cope with a temperature difference of more than 15℃
- Photo tips: solid color cotton and linen robes (khaki/ochre), matching the desolate background of the ruins
Bring Enough Water and Food
There are no restaurants in the scenic area, only a small shop at the gate with limited choices. It is recommended to prepare enough from the urban area:
