Bronze workshop unearthed along the Yangtze

Visitors to Chinese museums often admire ancient bronze wares for their beauty and their role in rigid ritual systems that shaped early Chinese civilization.

Yet, beyond their green patina and artistic refinement lies a more practical truth: bronze was once a strategic resource, central to livelihoods and the stability of the state.

Recent archaeological work at the Shenduntou site in Anhui province, near the southern bank of the Yangtze River, brings that reality into sharper focus. Over the past two years, excavations have uncovered around 1,000 artifacts linked to a bronze-casting industry dating back more than 2,500 years.

At first glance, many of the finds — simple-looking bronze knives, axes, spades, arrowheads, and broken components of furnaces and clay molds — may seem modest compared with the heavy ritual vessels displayed in museums. But these objects offer something arguably more valuable: crucial evidence of how bronze was produced, distributed, and managed on a large scale.

Located in Fanchang district of Wuhu city in southern Anhui, the site covers nearly 80,000 square meters. Archaeologists have excavated just 1,600 square meters, but the discoveries have already proved insightful. It marks the first time a large-scale bronze-casting site from the Zhou Dynasty (c. 11th century-256 BC) has been uncovered along the lower reaches of the Yangtze River.

"The discovery of numerous bronze-casting remains proves this was a high-level workshop," says Wang Zhigao, an archaeology professor at Nanjing Normal University, who is leading the project.

According to him, the site provides valuable physical evidence of a complete "state-controlled" system of bronze smelting and casting in southern Anhui. It sheds light on how governments managed metal resources, a key factor in maintaining power.

"In that era, bronze technology represented national strength, and the industry was strictly managed by governments," Wang explains.

"Whoever controlled bronze could produce superior weapons and tools."

This level of control is reflected in the site's layout. Furnaces and bronze artifacts were found within workshop areas enclosed by earthen walls and surrounded by moats, suggesting strict oversight and protection.
