The Stone Terraces or Staircases at Ollantaytambo, Peru
"Walk above the town to a formidable stone structure where massive terraces climb to the peak. It was the valley's main defense against the Antis tribes from the neighboring rainforests. Construction began during the reign of Pachacutec but was never completed.
The rose-color granite used was not mined in thi part of the Valley. The elaborate walled complex contained a temple to the sun, used for astronomical observation, as well as the Baños de la Ñusta (ceremonial princess baths), leading archaeologists to believe that Ollantaytambo existed for more than defensive purposes."
