For the first time, researchers have pinpointed Sui Dynasty Great Wall ruins within Beijing, offering fresh clues regarding the evolution of ancient military fortifications in the area.
According to HeritageDaily, the find took place at Changping Gudalinggou, where specialists from the Beijing Institute of Archaeology carried out excavations at a primitive Great Wall fortification zone from August to October 2026. Excavations covering approximately 800 square metres uncovered more than 60 artefacts, including pottery, porcelain and metal objects.
The discovered objects include building materials, daily-use goods, and weaponry that cover multiple eras, extending from the Northern Dynasties via the Sui and Jin dynasties. According to Shang Heng, deputy researcher at the Beijing Institute of Archaeology, the defensive complex was primarily constructed during the Northern Qi and Sui periods, while parts continued to be used during the Jin Dynasty.

“This is the first time that Great Wall remains from the Sui Dynasty have been discovered in Beijing,” Shang said, as reported by HeritageDaily.
The attribution is backed up by unearthing a Sui Wushu coin alongside ceramics featuring typical features of the Sui era. Having these time-sensitive artifacts allowed experts to link a section of the fortification network to the Sui Dynasty, an imperial Chinese regime spanning AD 581 to 618.
Rather than being a singular unbroken wall built all at once, the Great Wall consists of numerous barrier systems established, renovated, and broadened by various realms and emperors across long spans of history. Before the Sui Dynasty, the Northern Qi constructed extensive frontier fortifications across northern China.
Following this, the Sui kept up and broadened the protective infrastructure to help safeguard the northern borders of their realm. Consequently, the ruins located at Changping Gudalinggou serve as a vital historical benchmark for grasping the evolution of these older defensive systems throughout the Beijing area.
According to scientists, the find can assist in determining the building timelines, geographical placement, and alignment of initial Great Wall segments, while also shedding light on how related military defense operations were structured. Furthermore, the location can enable experts to draw comparisons between early Beijing defensive structures and Sui-era Great Wall ruins uncovered in other parts of northern China, such as Hebei and Shaanxi.
The find was made public at the conclusion of the 4th Beijing-Tianjin-Hebei Archaeological Exchange event, alongside the 2026 Beijing Public Archaeology Season. Up to this point, no sections of the Great Wall within Beijing had been scientifically verified as belonging to the Sui Dynasty.
The Changping Gudalinggou site provides a new chronological reference for reconstructing the development of the Great Wall and the military defenses surrounding ancient Beijing.
