A. Sutherland - AncientPages.com - Fascinating and mysterious underground Longyou Grottoes (also known as Longyou Caves) must have been some kind of an extraordinary man-made project of the ancient skilled builders, who created them more than 2000 years ago.
They have long been the subject of great fascination for both scholars and laymen alike but until now, no one was able to solve the mystery of their creation.
Researchers from several countries around the world visited and investigated the Longyou Grottoes, which are believed to date to a period before the creation of the Qin Dynasty in 212 BCE
Description Of The Caves
The caves are very large considering their man-made origin: the average floor area of each cave is over a 1,000 square meters(11,000 sq ft), with heights of up to 30 meters(98 ft), and the total area covered is in excess of 30,000 square meters (320,000 sq ft).
