Peru & Machu Picchu
The Sacred Plaza is built on a series of terraces that resemble a pyramid. The principal temple is at the lower level. A stairway leads up to the top, the site of the Hitching Post of the Sun - the most important shrine at Machu Picchu. The Intiwatana was most likely used to calculate the planting seasons. The Plaza is at a central point for important solar events and sacred peaks.
