Sacsayhuaman ("satisfied hawk" in Quechua, the Inca language) is divided into three vast zig-zagging terraces and flanked by massive stone walls, some up to 300 meters long.
As it lies close to Cusco, and due to the dimension of its stones -some of which stand 5 meters high and weigh over 300 tons- the site was used as a quarry to provide stone for colonial buildings in Cusco.
