DgcityFor more than a decade the crumbling stone fort at Dalinggou, high in the Changping hills north of Beijing, was listed simply as a Northern Qi dynasty wall. Excavations this summer and autumn have now shown that soldiers from a second, much rarer dynasty served there too. Investigators say the garrison is the first confirmed stretch of Sui dynasty Great Wall ever found within the Beijing area.
The dig ran from mid-August to early October across 800 square metres of the mountain post. Teams recovered more than 60 objects in pottery, porcelain and metal, ranging from building components and everyday vessels to weapons, with material spanning the Northern Qi, Sui and later Jin periods. Two finds did the decisive dating work: a Sui wuzhu coin, the standard bronze cash of the short-lived dynasty, and a porcelain vessel whose shape and workmanship match known Sui pieces closely.
The Sui lasted only 37 years, from 581 to 618, yet it reunified China after centuries of division and poured labour into frontier walls as it did so. Written records mention Sui building campaigns in the northern passes, but physical evidence around the future capital had remained elusive. The garrison’s main occupation is now placed in the Northern Qi and Sui, with Jin troops reusing the post centuries later.
Dalinggou sits on a forested ridge in Changping district, on the same defensive belt that guards the approaches from the steppe. Investigators say the discovery helps pin down the date, position and route of Beijing’s early walls, and should also clarify where Sui frontier lines ran through neighbouring Hebei and Shanxi. The announcement came as this year’s Beijing public archaeology season closed, alongside finds from several other sites across the capital region.
Sui wall-building deserves the attention. The dynasty’s founder, Emperor Wen, and his successor Yang ordered repeated frontier works to fend off the eastern Turkic khaganate, conscripting hundreds of thousands of labourers in single campaigns and linking older Northern Qi and Northern Zhou defences into longer lines. Those ramparts foreshadowed the grander Ming walls familiar to visitors today, yet little Sui masonry had been identified around the capital, which is what makes a datable garrison with coins and weapons so useful to researchers.
