Sacsayhuamán

Climbing the stone steps from Calle Suecia, leading off of Plaza de Armas, brings intrepid tourists to the large ruins of Sacsayhuaman. Unlike much of the ancient Incan city of Qosqo, the walls here weren't completely decimated by the conquistadores. The interlocking stones (some measuring more than 3m or 10ft in height) make for mightily imposing walls and demonstrate the Incan talent for engineering. After a decisive battle with Spanish conquistador Francisco Pizarro in 1536, many of the stones were carried down to Cusco below for building work.

Ascend a little way up the hill and you'll come to the site's 20th century addition, Cristo Blanco, a huge statue of Christ with outstretched arms à la Rio de Janeiro's Christ the Redeemer.
