Archaeologists found Beijing’s first Great Wall remains from the short-lived Sui dynasty

For years, a hillside garrison in Beijing’s Changping district sat in the national survey as a stretch of Northern Qi wall. A Sui-era coin and a piece of porcelain from the 2026 dig changed the label, and with it produced the first Sui dynasty Great Wall remains confirmed anywhere in Beijing.

Shang Heng of the Beijing Institute of Archaeology said so in plain terms at the announcement. The institute excavated 800 square meters of the site, known as Dalinggou, between August and October, and recovered more than 60 artifacts.

Dalinggou, a small military post against the wall

The Beijing Institute of Archaeology presented the results at the closing event of the 2026 Beijing Public Archaeology Season, held alongside the fourth Beijing-Tianjin-Hebei archaeological exchange on Saturday, Oct. 31, according to Ancient Origins. Global Times reports that the excavation ran from Aug. 16 to Oct. 9 and followed institute surveys of Beijing’s early Great Wall in 2022 and 2023. HeritageDaily spells the site name Gudalinggou, a variant of the same Changping location.

The site is a small military post built against the wall, with the post’s northern side formed by the existing wall. Inside, the team found building foundations and retaining walls. Construction used roughly hewn stone bonded and filled with loess around a core of mixed earth and stone, a simpler method than the Ming dynasty work (1368-1644) that most visitors to Beijing’s Great Wall see today. The wall there is therefore a rougher, older structure than the brick-faced sections on the tourist circuit, and its northern face is the early wall itself rather than a later addition.

A Sui coin and porcelain against a Northern Qi label

The 60-plus finds include pottery, porcelain and metal objects: architectural components, everyday goods and weapons. They span the Northern dynasties, the Sui and the Jin (1115-1234). The national survey had classed the wall as Northern Qi, which ruled from 550 to 577, so the site was treated for years as a single-period monument. Mixed finds from three periods in one small garrison tell a different story, of a position that kept being useful to whoever held the frontier.

The decisive evidence was small. A Sui wuzhu coin and porcelain whose shape and manufacture resemble known Sui pieces led the team to conclude that the garrison was used mainly in the Northern Qi and Sui periods, with evidence of Jin reuse later still. Medievalists.net adds that historical records point the same way. Shang said: “This is the first discovery of Sui-era Great Wall remains in Beijing.”

The Sui ruled China only from 581 to 618, about 37 years, and had until now left no confirmed Great Wall remains in the capital region. HeritageDaily notes that nothing in Beijing had previously been confirmed as Sui-era. That brevity and that gap are why one dated coin and one porcelain fragment carry so much weight here.

The same closing event announced other Beijing finds, per Medievalists.net: three wooden boats about 1,800 years old from Fengtai district, a new archaeological research station in Yanqing district, and the launch of a journal called Archaeological Science. The Great Wall result drew the attention because it revises a map, not because it adds an object to a shelf. A wall segment that had been filed under one dynasty now belongs to two, and each reclassification moves the chronology of everything built along that line.

Inscriptions in Hebei and Shanxi, and the route question

Beijing is not the only place where Sui wall building is documented. China Daily notes a 599 inscription recording Great Wall construction in Kelan county, Shanxi, a 597 inscription in Luanping county, Hebei, and a Sui beacon tower in Qianxi county, Hebei. Shang said the Dalinggou find should help trace Sui-era sections in Hebei and Shanxi, where the Sui may have reused extensive parts of Northern Qi fortifications.

That reuse is the institute’s working reading rather than a settled result. Shang also said the Beijing find will help refine the chronology, location, route and defense system of the early Great Wall in the capital, and that the scale of the work suggests early frontier walls were more substantial than previously assumed.

Preservation limits what the dig can answer. Shang said, per China Daily, that the scale of the work implies considerable labor and materials, which he reads as a sign of serious frontier investment. Residential areas near the outpost were heavily damaged by shallow burials and farming, so few well-preserved traces of daily life survived. China Daily adds one structural detail: the entrance used a jamb-column timber framework, a form Shang says was common from the Han dynasty through the Sui and Tang. Whether the Sui built new wall in Beijing, or only repaired and garrisoned a Northern Qi line, is a question the Dalinggou finds cannot yet settle on their own.
