Hatun Usnu

Hatun Usnu (also known as Qatun Ushno de Toccto) is an archaeological site in Peru's Ayacucho Region, Huamanga Province, Chiara District. The name means "big usnu" in Quechua, referring to a pyramid-shaped, terraced ceremonial platform used by the Incas for rituals involving liquid offerings poured into a sacred well. Such ushnu structures typically feature a rectangular pyramid of five terraced platforms topped with a stone throne where the Inca ruler presided over ceremonies. The site reflects the religious importance and complex ceremonial activities at Inca administrative centers in the Ayacucho highlands.
