The ruins are separated along the ridge into four groups: P'isaqa, Inti Watana, Qalla Q'asa, and Kinchiraqay. Inti Watana group includes the Temple of the Sun, baths, altars, water fountains, a ceremonial platform, and an inti watana, a volcanic outcrop carved into a "hitching post for the Sun" (or Inti). The angles of its base suggest that it served to define the changes of the seasons. Qalla Q'asa, which is built onto a natural spur and overlooks the valley, is known as the citadel.
The Inca constructed agricultural terraces on the steep hillside, which are still in use today.
