Longyou Caves
These caves, discovered in 1992, still remain largely a mystery in regards to their origin and construction. Located in thte Zhejiang province of China, about 36 underground grottoes have been discovered to date. The architecture includes bridges, gutters, pillars, and pools, among other things. There are no traces that construction ever took place, and no historical documents exist about the caves. The walls are chiseled in a parallel formation, which is uniform throughout, and seems to exist purely for decoration - decoration which would have required endless hours of work. Their purpose and who built them has never been discovered. The caves simply remain a beautiful mystery for now.
