The city of Cusco, the ancient capital of the Incan Empire, was placed on the World Cultural Heritage List by UNESCO in 1983, and is without a doubt one of the most important destinations in Peru. There are Incan buildings waiting for you to discover them among its cobble-stoned streets, ones like the Koricancha and the palace of Inca Roca as well as Andean Baroque structures from the Colonial Period like the Cathedral and the Church of the Company of Christ.
