Sacsayhuaman, the Royal Eagle Inca ruins in Cusco, Peru

Together with the city of Cusco, this monumental complex is considered the first of the new seven wonders of the world. This huge construction was planned and built by Andean Man. The Incas called it the House of the Sun and the Spaniards called it a fortress because of its zig-zag shape and the 1536 revolution. The construction, which is made up of three platforms one on top of the other, was one of the most important religious complexes of its time.
