Saksaywaman (aka Sacsayhuamán, Sacsahuaman) is a citadel on the northern outskirts of the city of Cusco, the historic capital of the Inca Empire.
Sections were first built by the Killke culture and the complex was expanded and added to by the Inca from the 13th century. The workers carefully cut the huge boulders to fit them together tightly without mortar. The site at an altitude of 3,701 m (12,142 ft) was added to the UNESCO World Heritage List in 1983.
