====Temple of the Sun or Torreón====
[[File: Machupicchu intihuatana.JPG|thumb|Temple of the Sun or Torreon|upright=1.2]]This semicircular temple is built on the same rock overlying Bingham's "Royal Mausoleum", and is similar to the [[Coricancha#Inca Astronomy|Temple of the Sun]] found in Cusco and the one found in [[Pisac]], in having what Bingham described as a "[[Parabola|parabolic]] enclosure wall". The stonework is of [[ashlar]] quality. Within the temple is a 1.2 m by 2.7 m rock platform, smooth on top except for a small platform on its southwest quadrant. A "Serpent's Door" faces 340°, or just west of north, opening onto a series of 16 pools, and affording a view of Huayna Picchu. The temple also has two [[trapezoidal]] windows, one facing 65°, called the "Solstice Window", and the other facing 132°, called the "[[Qullqa]] Window". The northwest edge of the rock platform points out the Solstice Window to within 2' of the 15th century [[June solstice]] rising Sun. For comparison, the [[angular diameter]] of the Sun is 32'. The [[Constellation#Dark cloud constellations|Inca constellation]] Qullca, storehouse, can be viewed out the Qullqa Window at sunset during the 15th-century June Solstice, hence the window's name. At the same time, the [[Pleaides]] are at the opposite end of the sky. Also seen through this window on this night are the constellations Llamacnawin, Llama, Unallamacha, Machacuay, and the star Pachapacariq Chaska ([[Canopus]]).<ref name="torreon"/><ref>{{cite book |last1=Krupp |first1=Edwin |author-link=Ed Krupp|title=Echoes of the Ancient Skies |date=1994 |publisher=Dover Publications, Inc. |location=Mineola |isbn=978-0-486-42882-6 |pages=47–51}}</ref>[[File: 143 Intiwatana Machu Picchu Peru 2406 (14977268637).jpg|thumb|right|''Intihuatana'' is believed to have been designed as an astronomic clock or calendar by the Incas|upright=1.2]]
