Ollantaytambo (Peru) – 10,000 years old
At the northern end of the Sacred Valley, Ollantaytambo is rare if not unique in Peru. Ollantaytambo is a massive citadel located 50 kilometers from Machu Picchu. The citadel served as both a temple and a fortress. At some time unknown, and for reasons unknown, work mysteriously stopped on this huge project.
The main quarries of Ollantaytambo were located at Kachiqhata, in a ravine across the Urubamba River some 5 kilometers from the town. The site features three main quarrying areas: Mullup’urku, Kantirayoq, and Sirkusirkuyoq; all of them provided blocks of rose rhyolite for the elaborate buildings of the Temple Hill. An elaborate network of roads, ramps, and slides connected them with the main building areas.
“How were such titanic blocks of stone brought to the top of the mountain from the quarries many miles away? How were they cut and fitted? How were they raised and put in place? Now one knows, no one can even guess. There are archaeologists, scientists, who would have us believe that the dense, hard andesite rock was cut, surfaced and faced by means of stone or bronze tools. Such an explanation is so utterly preposterous that it is not even worthy of serious consideration. No one ever has found anywhere any stone tool or implement that would cut or chip the andesite, and no bronze ever made will make any impression upon it.”
