The Inca’s Sacred City of Cuzco

At its height in the 14th century, the Inca ruled an Empire of 12 million people, in an area that encompasses six modern South American nations. Archaeologist Noah Corcoran-Tadd describes a ceremonial network based on the sun that allowed the Incan government to monitor its vast expanse. Using history records and GPS mapping, Corcoran-Tadd discovered sacred markers, called huacas, which formed a network defining the wider sacred world within the Empire. The huacas converge on the Temple of the Sun in Cuzco, the center of the Empire.
