Sacsayhuamán is an impressive Inca architectural complex located on a hill near the city of Cusco, in Peru. The name of this ancient fortress, which means "satisfied falcon" in Quechua, reflects its grandeur and power. Today, it is one of the most iconic sites demonstrating the engineering genius of the ancient civilization.
Originally, Sacsayhuamán served as both a military citadel and an important religious center. In the unique city plan of Cusco, which is believed to be shaped like a puma, this complex symbolizes its sharp teeth. According to historical records, the ruler and his court lived in its towers, while ammunition and provisions were stored in deep basements.
Most visitors are struck by the three massive zigzag walls built one above the other on the hillside.
