HILL IN MACHU PICCHU
The Principal Temple stands in front of this Sacred Hill.
Ascending the mound beyond this temple leads you to what was probably the most important of all the many shrines at Machu Picchu, the Intihuatana, the so-called "Hitching Post of the Sun." Nobody has ever unraveled the mystery of how this stone and others like it were used. It seems likely that the stones somehow served for making astronomical observations and calculating the passing seasons.
