The region around Parinacota has been inhabited for about 7,000–10,000 years. Politically, since 1,000 years ago first Tiwanaku and then the Inka ruled over the region. In contrast with many other local mountains, no archeological findings are reported from the summit of Parinacota. Several legends concern Parinacota and its sister mountain Pomerape, which are often portrayed as unmarried sisters. Some involve a dispute with or between the mountains Tacora and Sajama, often resulting in Tacora being driven off.
