Hidden within the Himalayas, 155 feet from the ground, these man-made caves are one of the World’s greatest archaeological mysteries.
Thousands of holes are carved into the fragile, sandy-colored cliff in a gorge so large it dwarfs the Grand Canyon.
The astonishing number of caves, some dug into the cliff side, others tunneled from above are thousands of years old but who built them and why remains a mystery.
