The Cathedral of Cusco has splendid altars of both Renaissance and Baroque style and neoclassical style. Its carved wooden pulpit and the choir stalls are magnificent works of Cusco craftsmanship. There is also an important collection of paintings from the Cusco school works by Diego Quispe Tito, Basilio Santa Cruz Pumacallo, Basilio Pacheco and Mark Zapata, who created a unique "Last Supper" in which the main dish is roast guinea pig.

According to Inca conception, the Qorikancha was the religious, geographical and political center of Cusco. It was the place where homage was paid to the highest of Inca deities, the “Inti” (Sun). Etymologically, the word “Qorikancha” is divided as follows: “Qori” means “worked gold”- its Spanish form is “cori”. “Kancha” means place enclosed or limited by walls- its Spanish form is “cancha”, which suggests that the name approximately corresponds to “fenced place that contains gold”. It is said that when the Spanish reached the Temple of Qorikancha, they had never seen so much gold in one place; the walls of the temple were covered with a layer of gold that illuminated the entire enclosure and in its extensive gardens there were representations of animals and cornfields made of pure gold. Most of the pieces were sent to Spain, as a “thank you” to the king for allowing the expeditions of conquest.

This immense ruin of both religious and military significance was built using megalithic limestone rocks, some of them weighing as much as 120 tons, The name itself can be translated as “speckled head” and some say that the city of Cusco was laid out in the shape of a puma, with Sacsayhuaman forming the head.

​It was one of the most important wak'as (holy places) in the Incan Cusco. Many wak'as were based on naturally occurring rock formations. It was believed to be a place where sacrifices and mummification took place.
