Embark on a guided sightseeing tour of Cusco that focuses on the city that was once the political, military, and cultural epicenter of the Incas until the Spanish toppled it. In fact, Inca foundations can still be found in Cusco, with the Spanish baroque structures built on top. Visit the SANTO DOMINGO MONASTERY, where these two forms of architecture are melded together with the temple of both cultures atop one another. Also see the CATHEDRAL in the Plaza de Armas, housing a magnificent collection of artwork, including a depiction of The Last Supper that portrays the apostles dining on cuy (guinea pig). Continue to the hillside overlooking Cusco for a visit to the TEMPLE OF SACSAYHUAMAN. Some of the best examples of Inca masonry can be found at this fortress, where stones weighing up to 350 tons are pieced together to form a complex that could house up to 10,000 men. Learn about the ceremonies and battles that took place here, then see the ruins of Kenko and Puca Pucara before returning to Cusco.
