Killke

The Killke were a highland people of the Cusco basin before the Incas; their archaeological culture dated from about 900 to 1200. In the twelfth century they built early fortifications, a temple and canals at Sacsayhuamán above Cusco.

The Inca state formed in the Cusco valley in the thirteenth century, incorporating Killke lands and traditions. In the fifteenth century the Incas expanded Sacsayhuamán over the earlier site, building walls of huge stones without mortar.
