900-year-old rocks so perfectly fitted, modern science still can't crack the code.
Sacsayhuamán, an ancient citadel amidst the Peruvian Andes, is an architectural marvel. It was built more than 900 years ago, and no living person knows how such large rocks were fitted so perfectly into walls. This documentary takes us on a tour of Sacsayhuamán, offering a brief history of the site, and clues that may help to its understand how it was made. It was edited from photos and video taken in July 2012, when Russian geophysicists conducted soil research there, at the request of Peru's Ministry of Culture.

Trivia, insights & behind the scenes
The 2012 research expedition was officially sanctioned by Peru's Ministry of Culture, yet the resulting 'documentary' has the production values of someone's vacation slideshow.
Sacsayhuamán's stones weigh up to 200 tons each, fitted without mortar so precisely you can't slide a razor blade between them — and this 40-minute film somehow makes that boring.
