Carved into solid siltstone, each grotto descends around 30 meters underground and contains stone rooms, bridges, gutters, and pools. The quantity of rock that would have been removed in the overall excavation of the grottoes is estimated to be nearly 1,000,000 cubic meters.

An extensive and rare ancient underground world considered in China as ‘the ninth wonder of the ancient world’. One of the largest underground excavations of ancient times.

Scientists from around the world in the fields of archaeology, architecture, engineering, and geology have absolutely no idea how they were built, by whom, and why.

Where this gets strange:

  • No traces of construction or mention in any historical records.
  • Excavation involved almost a million cubic meters of stone but there is no evidence of where it went.
  • The caves have 100%  structural integrity with zero damage over time.
  • No evidence of any lamps or soot from torches in what would have been pitch black caves.
  • They were not connected to each other.
  • Marks on the walls resemble modern-day high-tech machine dig marks.

  3. Yet more evidence – no, PROOF – of advanced ancient technology (the lack of soot/smoke marks being because of electric lighting). I highly recommend reading “Dead Men’s Secrets” by Jonathan Gray.
