Sanxingdui, whose name means “Three Star Mound,” is a Bronze Age archaeological site in Guanghan, Sichuan, China. It was first noticed in 1927 when a farmer uncovered jade relics while cleaning an irrigation ditch, but the major discovery came in 1986, when workers stumbled upon sacrificial pits. Radiocarbon dating places the artifacts from these pits in the 12th–11th centuries BC. The site is the type site for the Sanxingdui culture, and many Chinese archaeologists link it to the ancient kingdom of Shu, a civilization that existed in the region before the Qin state conquered it in 316 BCE.
The kingdom of Shu appears in historical texts like the *Shiji* and *Shujing* as an ally of the Zhou against the Shang. Local annals, such as the Jin-dynasty *Chronicles of Huayang*, describe legendary Shu rulers: Cancong, said to have protruding eyes—a feature seen in many Sanxingdui masks and figures—along with Boguan, Yufu (whose name means “fish cormorant”), and Duyu. Eye-shaped objects found at the site may indicate eye worship, while fish- and bird-shaped artifacts are thought to represent totems of Boguan and Yufu. The Yufu clan is often considered the most likely to be associated with Sanxingdui. Later discoveries at Jinsha, 40 kilometers away, show close cultural ties and may mark a relocated Shu capital, possibly under the Duyu clan.
The archaeological site itself lies about 4 kilometers northeast of Nanxing Township, Guanghan, in Deyang, Sichuan. Evidence points to a walled city founded around 1600 BCE. Its trapezoidal layout includes an east wall 2,000 meters long, a south wall of the same length, and a west wall 1,600 meters long, enclosing 3.6 square kilometers—comparable in scale to the inner city of Zhengzhou Shang City. Built on the banks of the Yazi River, the city incorporated part of the Mamu River tributary within its walls. The walls were 40 meters wide at the base, 20 meters at the top, and 8–10 meters high, with a smaller inner wall system. Canals 25–20 meters wide and 2–3 meters deep surrounded the walls, used for irrigation, navigation, defense, and flood control. The city was divided into residential, industrial, and religious districts along a central axis, where most pit burials were found on four terraces. Structures were timber-framed adobe rectangular halls, the largest being a meeting hall of about 200 square meters.
The initial 1927 discovery of jade relics led to private collectors acquiring many pieces. In 1931, Anglican missionary Vyvyan Donnithorne, stationed in Guanghan, recognized the find’s importance and contacted the local magistrate and Daniel Sheets Dye, a geology professor at West China Union University. They photographed and measured the site, and a few items were sent to the university’s museum. In 1934, David Crockett Graham, the museum’s new director, conducted the first formal excavation. In 1986, workers accidentally found sacrificial pits containing thousands of gold, bronze, jade, and pottery artifacts—many broken, burned, and carefully buried. The second pit, discovered about a month later on August 14, 1986, only 20–30 meters from the first, held roughly 800 objects. Bronze items included human and animal-faced sculptures, bells, decorative animals (dragons, snakes, chicks, birds), and axes. Gold objects included tables, masks, and belts; jade items included axes, tablets, rings, knives, and tubes. Ivory carvings and clam shells were also present. Researchers were astonished by an artistic style previously unknown in Chinese art history.
The bronze artifacts drew exceptional scholarly attention. Task Rosen, chief archaeological expert from the British Museum, considered them more outstanding than the Terracotta Army in Xi’an. First exhibits of Sanxingdui bronzes were held in Beijing in 1987 and 1990, and at the Olympic Museum in Lausanne in 1993. Despite interest in the finds, the site suffered from flooding and pollution, leading to its inclusion in the 1996 World Monuments Watch by the World Monuments Fund. Today, the artifacts are displayed at the Sanxingdui Museum near Guanghan, and the site is on UNESCO’s tentative list of World Heritage Sites, along with the Jinsha site and tombs of boat-shaped coffins.

Lore & Background
In 1986, workers accidentally discovered sacrificial pits at Sanxingdui containing thousands of artifacts made of gold, bronze, jade, and pottery, many of which had been broken, burned, and carefully buried. A second pit, found about a month later and only a short distance from the first, yielded bronze sculptures of humans and animal-faced figures, bronze bells, decorative animals such as dragons, snakes, chicks, and birds, as well as bronze axes. Gold objects included tables, masks, and belts; jade items comprised axes, tablets, rings, knives, and tubes. The pits also contained numerous ivory carvings and clam shells. The artistic style of these objects was completely unknown in the history of Chinese art, surprising researchers. Among the bronze artifacts, large heads with gold foil masks and a notable bronze head with protruding eyes were found, the latter possibly representing Cancong, the semi-legendary first king of the ancient Shu kingdom, as described in later Jin dynasty chronicles. Other eye-shaped objects suggest a possible worship of eyes. Fish- and bird-shaped items may relate to later Shu rulers named Boguan and Yufu. The site, located near Guanghan in Sichuan, is the type site for the Sanxingdui culture and is identified with the ancient kingdom of Shu, indicating a unique civilization predating the Qin conquest of 316 BCE.
Reader's Guide
Sanxingdui represents a major Bronze Age civilization in southern China, contemporaneous with the Shang dynasty but with a distinct artistic style. The artifacts, including large bronze masks with protruding eyes and a gold mask, suggest a strong central theocracy with trade links to bronze from Yin and ivory from South Asia. The site's walled city, with canals for irrigation and defense, and its division into residential, industrial, and religious districts, indicate advanced urban planning. The culture's end may have resulted from natural disasters or invasion. Sanxingdui's significance lies in challenging traditional narratives of Chinese civilization as solely centered on the Yellow River, highlighting a unique Shu kingdom. Its inclusion on the UNESCO tentative list underscores its global importance.

The Long Road to Discovery
Over the following years, many of these pieces drifted into private collections. The three visited the location, documented it with photographs and measurements, and secured a few items for the university museum. The story took a dramatic turn in 1986, when local workers accidentally uncovered sacrificial pits holding thousands of gold, bronze, jade, and pottery artifacts—many of which appeared to have been ritually broken, burned, and deliberately interred. A second pit, containing roughly 800 objects, was located just 20 to 30 metres away in August of that same year.
Artifacts That Defied Expectations
The objects pulled from the sacrificial pits stunned researchers with their unfamiliar artistic vocabulary. Bronze sculptures of humans and animal-faced figures, decorative dragons, snakes, chicks, and birds, ceremonial bells, and axes dominated the assemblage. Gold yielded tables, masks, and belts, while jade produced axes, tablets, rings, knives, and tubes. Ivory carvings and clam shells rounded out the collection. What struck scholars most was the complete absence of any parallel in the known history of Chinese art. Task Rosen, the British Museum's chief archaeological expert, judged the bronzes to be more outstanding than the famous Terracotta Army at Xi'an.
The Kingdom of Shu and Its Legendary Rulers
Many Chinese archaeologists have linked the Sanxingdui culture to the ancient kingdom of Shu, a polity mentioned in the Shiji and Shujing as a Zhou ally that defeated the Shang. The Chronicles of Huayang, compiled during the Jin dynasty, name a succession of legendary Shu kings: Cancong, Boguan, Yufu, and Duyu. Cancong is described as having protruding eyes—a feature echoed in many of the site's large masks and figures, leading some scholars to propose that these masks are portraits of him. Other eye-shaped objects found at the site hint at a broader cult of the eye. The fish- and bird-shaped artifacts have been interpreted as totems of Boguan and Yufu, whose name literally means 'fish cormorant.' The Yufu clan is considered the most likely candidate for the community behind Sanxingdui. A closely related site, Jinsha, lies 40 kilometres away and is thought to represent the relocated Shu capital, possibly the seat of the Duyu clan.
A Walled City and Its Modern Preservation
Excavations revealed a trapezoidal walled city founded around 1600 BCE, situated on the banks of the Yazi River and enclosing part of its tributary, the Mamu River. The east and south walls each stretched 2,000 metres, the west wall 1,600 metres, enclosing 3.6 square kilometres—an area comparable to the inner city of the Zhengzhou Shang City. The walls rose 8 to 10 metres in height, with a base width of 40 metres and a top width of 20 metres. Surrounding canals, 20 to 25 metres wide and 2 to 3 metres deep, served irrigation, inland navigation, defense, and flood control. The city was organized along a dominant central axis into residential, industrial, and religious districts, with timber-framed adobe halls, the largest being a meeting hall of about 200 square metres. Pit burials clustered on four terraces along this axis. The site now sits on UNESCO's tentative World Heritage list alongside Jinsha and the boat-shaped coffin tombs.
