The City at the Edge of the Sky

On the Bolivian altiplano, at nearly four thousand meters above sea level, a civilization built one of the greatest cities of the ancient Americas. They moved stones weighing hundreds of tons across a treeless plain with no wheels and no large animals. They built a calendar so precise it could predict eclipses. And then, around 1000 CE, they abandoned everything, possibly because a drought lasting decades dried up the lake that had sustained them for centuries. Tiwanaku. The city that touched the sky. #AncientHistory #LostCities #Tiwanaku #Bolivia #Archaeology #SleepDocumentary #Andes #LostCivilization #HistoryDocumentary #AncientAmericas
