CUSCO, Peru (INTELLIHUB) — To this day it is a mystery how the Inca built Coricancha so precisely.
In fact, the structures stones fit so perfectly that no mortar was needed in the construction.
How were the angles so precisely calculated and created?
“[Coricancha] is one of the technical marvels of the ancient world because of the exactness of the craftsmanship,” archeologist Brian Forester said.
Moreover, there a holes in various blocks which also bear score marks as if machinery was used during the construction process.
One of the archeologists concludes the hole appears to be a “core drill” which may signify the use of advanced machinery.
