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

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. Travellers 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

Commonly referred to as the 'Banos del Inca' or Inca baths, Tambomachay was a site for ritual swimming. The excellent quality of the stonework suggests that its use was restricted to the higher nobility, who maybe only used the baths on ceremonial occasions. The ruins basically consist of 3 tired platforms. The top one holds four trapezoidal niches that perhaps were used as seats; on the next level an underground spring emerges directly from a hole at the base of the stonework and from here cascades down to the bottom platform, creating a cold shower just high enough for an Inca to stand under. On this platform the spring water splits into two channels, both pouring the last metre down to ground level

Today’s site is a bizarre combination of Inca and colonial architecture, topped with a roof of glass and metal. In Inca times, Qorikancha (Quechua for ‘Golden Courtyard’) was literally covered with gold. The temple walls were lined with some 700 solid-gold sheets, each weighing about 2kg. There were life-sized gold and silver replicas of corn, which were ceremonially ‘planted’ in agricultural rituals. Also reported were solid-gold treasures, such as altars, llamas and babies, as well as a replica of the sun. But within months of the arrival of the first conquistadors, this incredible wealth had all been looted and melted down.

The cathedral is one of the city’s greatest repositories of colonial art, especially for works from the escuela cuzqueña (Cuzco school), noted for its decorative combination of 17th-century European devotional painting styles with the colour palette and iconography of indigenous Andean artists. A classic example is the frequent portrayal of the Virgin Mary wearing a mountain-shaped skirt with a river running around its hem, identifying her with Pachamama (Mother Earth).
