Lost Cities with Albert Lin S01 E06 Inca Island in the Sky

"A mission to discover and re-create unexcavated worlds still hidden beneath the earth."

Albert Lin travels to the mountains of Peru to discover the origins of its most famous site, Machu Picchu. Using LiDAR technology, he finds proof of the people who came before the Inca and treks into the mountains to find their homes and ceremonial sites. Lin reveals that the Inca city may have been inspired by another, even older civilization.
