At the heart of Qiandao Lake, a submerged city captivates with its mysterious beauty and relics frozen underwater for decades. Heritage and history enthusiasts face a puzzle: how could such a vast historical site survive intact, preserved by the depths and modern technology, while the rise of tourism often threatens the authenticity of such places? My field experience, between local encounters and underwater expeditions, allows me to provide you with a precise view of the conservation challenges, architectural treasures, and innovations that are transforming the way we approach this exceptional site.
How did the city of Shi Cheng end up submerged under a lake?
The submerged city of Shi Cheng now rests beneath the calm waters of Qiandao Lake. This unique site was flooded in 1959 during the construction of a hydroelectric dam on the Xin’an River, transforming the entire region and giving birth to a vast body of water with a thousand islands.
Before this submersion, the City of Lions was a major historical site, the seat of the Sui’an county, hosting a dynamic local life. Approximately 300,000 people were relocated during the rising waters, inadvertently preserving the ancient structures under 26 to 40 meters of depth.
Main events leading to the submersion
- Construction of the hydroelectric dam on the Xin’an River
- Creation of Qiandao Lake and flooding of the valley
- Relocation of 300,000 inhabitants
- Submersion of Shi Cheng’s ruins and paved roads
- Natural protection of the submerged archaeological site
What architectural and historical treasures lie beneath the waters of Qiandao?
The remains of Shi Cheng reveal an exceptional archaeological site, preserved thanks to the protection of the deep waters. There are temples, traditional houses, paved roads, and 265 stone arches dating from the 18th century, showcasing the architectural refinement of imperial China.
The structures of the City of Lions include five entrance gates, a rare feature, and walls dating from the 16th century. This submerged historical site offers a unique insight into ancient urban life, intact underwater for more than sixty years.
