Archaeologists Uncovered 573 Ancient Fortresses Concealed in the Mountains

In the mountainous region surrounding Yulin, China, researchers have identified 573 previously unknown stone fortress settlements, some dating back to 2800 B.C.E. Each fortress is positioned near important water sources, and several are linked to neighboring settlements, revealing possible social structures of the time.

The discovery follows a six-year survey conducted by Yulin's cultural heritage and archaeology team across Shaanxi Province. The team documented sites from different historical periods: the Yangshao period (starting 2800 B.C.E.), the Shang Dynasty (16001046 B.C.E.), and the Zhou Dynasty (1046221 B.C.E.).

Stone fortresses were primarily found along rivers, a strategy that guided researchers to their locations. Utilizing both ground exploration and aerial mapping, the team was able to locate and study these ancient sites in detail. Many fortresses were situated beside smaller, non-fortified settlements. According to Ma Mingzhi, the team leader, there was a clear connection between fortified and non-fortified clusters, suggesting that the stone fortresses acted as central hubs.

The complexity of the sites varies considerably. While some fortresses were simple and small, othersoften from later periodsfeatured sophisticated interior layouts and advanced construction techniques. Across all sites, Mingzhi noted visible indicators of social hierarchy, highlighting organized community structures even in early settlements.

Building walled settlements near water sources was a common practice in ancient times, and the Yulin discoveries underscore this strategic approach. Similar patterns have been observed elsewhere, including a walled city in northern Saudi Arabia, dating to 2,400 B.C.E., which supported a population of around 500 and exhibited a structured social hierarchy.

Mingzhi emphasized that the 573 fortresses provide an unprecedented opportunity to study the evolution of prehistoric settlements in China, offering insights into defensive architecture, community planning, and the movement of societies and cultures over millennia.
