Pisac Adventure Tours
The hillside is lined with agricultural terraces constructed by the Incas. These terraces are still used today. With military, religious, and agricultural structures, the site served at least three different purposes. Besides a country estate, it is thought that Pisac defended the southern entrance to the Sacred Valley, while Choquequirao defended the western entrance and the fortress at Ollantaytambo protected the northern entrance.
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.
