Vilcashuaman is an Inca provincial administrative center in the Ayacucho region of central Peru at 3,490 metres elevation, founded in the late 15th century after the Inca conquest of the local Chanka and Pokra populations. The site is centered on a great trapezoidal plaza measuring approximately 360 by 170 metres and dominated by the Ushnu — a stepped pyramid of fine ashlar masonry rising in five terraces, topped with a carved stone seat reserved for the Inca during state ceremony. This is the only surviving Inca pyramid platform of this configuration. Adjacent to the plaza is the Temple of the Sun, partially incorporated into the foundations of the colonial Iglesia de San Juan Bautista. Pedro Cieza de Leon estimated that 30,000 people gathered here for state functions during the imperial period.
The Ushnu pyramid still stands intact, its terrace courses tightly fitted, with the carved stone throne preserved at the summit.
