Outside the city of Xi’an in China’s Shaanxi province lies one of the most extensive funerary complexes ever built, an underground army of thousands of life-sized clay soldiers created more than two thousand years ago to guard the tomb of the man who first unified China. Farmers digging a well in 1974 stumbled onto the buried pits by accident, uncovering what would turn into one of the most significant archaeological finds of the twentieth century. Even now, the tomb the army was built to protect has never been opened.
An Army Built for the Afterlife
The terracotta figures were commissioned by Qin Shi Huang, who unified the warring states of China under a single empire in 221 BCE and ruled as its first emperor until his death in 210 BCE. Historical and archaeological evidence indicates the army was intended to protect the emperor in the afterlife, continuing a long tradition of burying rulers with symbolic protection and provisions, though on a scale and level of craftsmanship far beyond anything built before it.
Roughly Eight Thousand Individual Soldiers
Excavations across several pits have so far revealed an estimated 8,000 soldier figures, along with hundreds of horses and dozens of wooden chariots, according to the overview maintained on Wikipedia’s Terracotta Army entry. Each soldier was assembled from separately molded components, including the head, torso, arms, and legs, then finished with individualized facial features, hairstyles, and armor details so that no two figures in the army are identical. Ranks are distinguishable by uniform and posture, with infantry, archers, cavalry, and officers arranged in battle formation exactly as a real Qin-era army would have deployed.
A Tomb Still Sealed by Choice
The soldiers stand roughly a mile from the emperor’s actual burial mound, which remains unexcavated more than two thousand years after his death. Ancient accounts written by the historian Sima Qian describe a subterranean palace beneath the mound filled with replica rivers of flowing mercury, a description long treated as legend until modern soil surveys around the tomb detected unusually high concentrations of mercury, lending the ancient account new credibility. Archaeologists have deliberately left the central tomb untouched, citing both the risk of damaging fragile contents on exposure to air and the practical hazard posed by any mercury still present underground.
Color That Faded Within Minutes
When first unearthed, many of the terracotta figures still carried traces of the vivid lacquer paint that once covered them, in shades of red, green, blue, and purple. Exposure to the dry air of the excavation site caused that paint to curl and flake away within minutes in many cases, a loss that pushed conservators to develop new techniques for stabilizing pigment on more recently excavated figures. Ongoing excavation proceeds slowly and carefully in acknowledgment of that early damage, with large sections of the site still left buried until better preservation methods are available.
Bronze Weapons That Never Rusted
Alongside the soldiers, excavators recovered thousands of real bronze weapons, including swords, spears, crossbow triggers, and arrowheads, many of which were found remarkably free of corrosion after more than two thousand years underground. Researchers have credited that preservation to a combination of the weapons’ bronze alloy composition and burial conditions, and some blades were found still sharp enough to cut when they were first lifted from the soil. The find gave historians an unusually direct look at Qin-era military technology, since organic materials like the wooden shafts and leather fittings that once accompanied the metal components had largely decayed, leaving the durable bronze pieces as the clearest surviving evidence of how the army was actually equipped.
Farmers Who Found More Than a Well
The 1974 discovery began when a group of farmers digging a water well in a drought-stricken area southeast of Xi’an struck fragments of a clay figure a few feet underground. Local archaeologists were called in soon afterward, and what began as a routine agricultural project quickly turned into a full excavation as it became clear the fragments belonged to a much larger buried formation. The farmers received little immediate recognition for the find, though the site has since grown into one of China’s most visited archaeological attractions, and some of the original well-diggers later worked at the site or signed replicas of the figures for visiting tourists.
A World Heritage Site Still Being Uncovered
The Terracotta Army was added to UNESCO’s World Heritage List in 1987, and the site now draws millions of visitors each year to view the excavated pits near the emperor’s mausoleum complex. Archaeologists estimate that significant portions of the surrounding pits remain unexcavated, meaning the current count of roughly 8,000 figures could still grow as work continues. More than four decades after the initial discovery, the site continues to yield new figures, weapons, and details about the empire that built them.
