Sacsayhuamán stands as a testament to the architectural ingenuity of the Inca Empire. Constructed without the use of mortar, the walls are comprised of massive stones that have been cut and stacked with precision. This fortress, which overlooks the city of Cusco, was an important site for the Incas, both strategically and ceremonially. Today, it is recognized as a UNESCO World Heritage Site and continues to draw visitors from around the world, fascinated by its history and the skillful craftsmanship of its builders.
