The mountain was considered to be sacred by the ancient inhabitants of the region. Pichu Pichu is visible from the Wari site at Cerro Baúl and some buildings at that site are constructed in such a way as to point to Pichu Pichu. Processions along the hillside staircase of Cerro Baúl would have the mountain in view. Stone structures are also found on Pichu Pichu itself, including a high altitude staircase that overcomes a steep pitch. Human sacrifices, so-called capacochas, were performed on Pichu Pichu. Mummies were found on the mountain in 1964 along with various archeological findings, but the findings were not published out of fear to avoid attracting graverobbers. An additional body was found in 1996. Overall, three mummies were found on Pichu Pichu. They were probably two females and one male, all 15 years old.
