About Pisac

The Inca constructed agricultural terraces on the steep hillside, which are still in use today. They created the terraces by hauling richer topsoil by hand from the lower lands. The terraces enabled the production of surplus food, more than would normally be possible at altitudes as high as 11,000 feet. The narrow rows of terraces beneath the citadel are thought to represent the wing of a partridge (pisaca), from which the village and ruins get their name. The birds are also common in the area at dusk.

With military, religious, and agricultural structures, the site served at least a triple purpose. Researchers believe that Písac defended the southern entrance to the Sacred Valley, while Choquequirao defended the western entrance, and the fortress at Ollantaytambo the northern. Inca Pisac controlled a route which connected the Inca Empire with the border of the rain forest
