English: Vilcashuamán was an Inca administrative center, established after the Incas conquered the Chancas and the Pocras. According to chroniclers, Vilcashuamán was home to 40,000 people. The city was located around a large plaza where ceremonies involving sacrifices were performed, usually camelids or libation of corn wine. Around this plaza were the city's two most important buildings: the Sun Temple (Templo del Sol) and the Usnu which remain to this day. It is believed that the city had the shape of a falcon, in which the Usnu was located in the head.
