The Mysterious Intihuatana Stone

Location

The Incas built multiple intihuatanas along their territory, but many of them were destroyed by Spaniards, who considered them to be blasphemous. Among the ones that remain, the most well-preserved are located at the archeological sites of Machu Picchu and Pisac. However, the most notable and famous Intihuatana Stone is located at Machu Picchu: it was found intact in 1911.

Machu Picchu’s Intihuatana Stone is located at the top of a natural pyramidal summit, whose slopes have been converted into terraces or andenes. A twisting stone ladder leads to the top of this pyramid.

Design and characteristics

The Intihuatana Stone is a monolithic structure carved out of the gray granite stone of the mountain top. It is 1 to 2 meters tall and 2 meters in diameter. Its base does not have a defined shape, but its crest is formed into an upright stone column whose four sides indicate the four cardinal points: North, South, East, and West. In addition, it features a granite block resembling a bench or altar, where the priest would likely have performed some type of ritual.

Function

The sacred Intihuatana Stone was used by Inca priests for astronomical observations, especially of the sun. We know that it was aligned with the sun’s position because it has been shown to be a precise indicator of the date of the two equinoxes. At midday on March 21st and September 21st, the sun stands almost directly above the pillar, creating no shadow at all. At this precise moment, when the sun aligns precisely with the pillar, the priests symbolically tied the sun to the Intihuatana Stone using a sacred cord.
