History is vital to society for a better understanding of who we are and where we come from. We can use the lessons of yesterday to plan for the future and avoid making the same mistakes over and over again. We see history all around us in the structures we build and preserve but some things we just aren’t sure about. Across the globe, there are many places that were obviously constructed for a purpose but either were built pre-recorded history or the information has been lost or destroyed over time and so historians and archaeologists can only speculate, albeit with educated guesses, as to the mysterious origins of these structures. Here are just a few.
10Longyou Caves – Zhejiang Province, China
Discovered in 1922, these caves are clearly of human-made design as they are carved out of the siltstone in Phoenix Hill. Believed to be created sometime before the Qing dynasty, which started around 212 BC, they are extremely large considering the era in which they were carved as the average floor area of each of the 24 caves found to date is over a thousand square meters, with heights of up to 30 meters, and the total area covered is in excess of 30,000 square meters.
No historical records exist to suggest any reasoning behind their existence so whether they were intended as a place of residence or storage remains a mystery today.
