Q'enko (Zigzag)

This is one of the finest examples of a rock artfully carved insitu showing complex patterns of steps, seats, geometric reliefs and a puma design. The rock is an excellent example of the Inca 'Rock Worship'. In Inca cosmological beliefs the Incas held large rocky outcrops in reverence, as if they possessed some hidden spiritual force. On top of the rock are zigzag channels which served to course chicha (local maize beer) or sacrificed llama blood for purposes of divination; the speed and route of the liquid, in conjunction with the patterns made in the rock, gave the answers to the priest's invocations.
Inside the rock are large niches and a possible altar. This may have been a place where the mummies of lesser royalty were kept along with gold and precious objects.

Puca Pucara (Red Fort)

Situated on a hill with superb views over the surrounding countryside Puca Pucara was more likely a tambo, or kind of post house than an actual fortress. Travelers may have lodged here with their goods and animals before entering or leaving Cusco. An alternative theory is that it served as a guard post controlling the flow of people and produce between Cusco and the Sacred Valley.
