Situated next to the Three-Windowed Temple, this magnificent three-walled building derives its name from the immense foundation stones and fine stonework that comprise its three high main walls. The wall facing furthest east looks onto the Sacred Plaza. In contrast to most ancient temples in the Americas, whose entrances face east, the Principal Temple's entrance faces south. White sand found on the temple floor suggests that the temple may have been tied symbolically to the Río Urubamba, a theory that is not too farfetched considering the importance of water in the ancient Inca culture. The kite-shaped sacred stone sitting in the small square around the temple is thought to represent the Southern Cross constellation. A short stroll uphill from here brings you to one of the most spectacular sites of Machu Picchu, the Intihuatana, or Hitching Post of the Sun.
