Usnu

Usnu is an archaeological site in Peru that is located in the Ayacucho region of the Vilcas Huaman Province in the Vilcas Huaman District in the town of Vilcashuaman. The site was declared a National Cultural Heritage of Peru in 2000. Excavation and research at the site took place in 1999, 2003, and from 2006 - 2010.

The site is believed to be to have been a principal part of Inca culture. It is said to be very important, a sacred space. It is believed that it was a collection of beautiful buildings and a temple that gave off the appearance of great wealth. The Inca burned most of the treasures and important buildings and removed sacred women so that the Spaniards could not get their hands on them. Many royal highways lead to this site in the Vilcas.

Inca architecture is often associated with ritual events such as performances of speech, dance and music. This particular building has a pyramid-shape and was made using different levels of steps. The ritual performances that were performed here made this specific site a very important historical site.

The structures such as the one found at Ayacucho are commonly found throughout Peru and have become an architectural signature of the Inca culture.
