Ancient Chinese Caves Designed As Water Collectors That Never Dry Up!

Pre-historic China is home to some of the most incredible structures that hint at advanced civilizations long before our current historical records begin. Among these are the Yangshan Quarry, the Longyou Caves, and the numerous pyramids scattered throughout China, often shrouded in mystery and suggesting a legacy of pre-flood megastructures. All of these ancient sites and megalithic structures have some kind of machine marks that suggest they were built by an advanced civilization lost to history.

The caves were discovered by accident in 1992, when local farmers drained several ponds revealing five large manmade caverns and 19 smaller caves.

The five caverns, independent from each other measure between 18-34 meters, reaching heights of up to 20 meters with supporting pillars and distinctive shapes remarkably curved with shaking imprints across the cavern walls and ceilings.

After news of the discovery spread across China, it was first proposed that the caves were an obscure natural wonder, as the design and formation was completely distinct from other ancient caves, quarries, mines, or ceremonial caverns constructed in china throughout antiquity to draw a comparison.

Upon further study, it was found that each complete cavern has only one portal, associated with a vertical shaft with a carved stairwell that allows rainfall and surface runoff to enter the caverns. To manage the water intake, a system of drainage troughs, some drainage channels, and a water trap was carved into the cavern base to collect the water.

The caverns are also aligned along a south to southwest orientation, maximizing the use of sunlight to illuminate the interior, with inclined sidewalls that reduces the stress on the cave ceilings preventing collapse.

Archaeologists have recovered glazed clay pots in the silt soils of the cavern floor, dated to the Western Han Dynasty from 206 BC to AD 23, which suggests the caves were constructed earlier and date from around 2,000 years ago.
