Ancient Bunkers in China Created more than 2,000 years ago!

The #Longyou Caves also called the Xiaonanhai Stone Chambers are a group of 24 artificial sandstone caverns located at Fenghuang Hill, near the village of Shiyan Beicun on the Qu River in Longyou County, Quzhou prefecture, Zhejiang province, #China. Created more than 2,000 years ago, they were not recorded in any historical documents and were rediscovered by farmers in 1992. In June 1992, four farmers in Longyou #discovered the caves by accident when they drained the water of five small ponds in their village. The ponds turned out to be five large manmade caverns. Further investigation revealed 19 more caverns nearby. They have been determined to be more than 2000 years old, and their construction is not recorded in any historical documents.
