Megalithic Sacsayhuaman: HOW IT WAS BUILT

Historical accounts, quechua legends, academic papers, cited sources, explorer journals, mortar that disappears? a mixture that vitrifies stone? Is there some truth to myths? ...it's all in here and more.

Going well beyond what's presented in Graham Hancock's Ancient Apocalypse - analyzing what we know, don't know, what's been found, and what hasn't - without cherrypicking the material and backing things up at every possible point.

Sacsayhuaman, stones, construction methods, new Sacred Valley discoveries - this video covers a lot more ground than was initially intended as the rabbit hole just kept going.
