Wari culture
The anthropomorphous sarcophagi resemble imitations of funeral bundles provided with wooden masks typical of the "Middle Horizon", a dominant culture on the coast and highlands, also known as the Tiwanaku–Wari culture. The "mausoleums" may be modified forms of the "chullpa" or "pucullo", elements of funeral architecture observed throughout the Andes, especially in the Tiwanaku and Wari cultures.
