It is a spectacular fortress, or temple as it´s called now, built with huge carved rocks laid together with absolute precision. Along with Machu Picchu and Choquequirao, it is undoubtedly one of the greatest architectural works of Tawantinsuyu. Its Quechua name means "satisfied falcon". It was erected on a high hill that overlooks the entire city and this falcon was believed to stand guard over the empire. Cusco was designed in the shape of a puma with Sacsayhuaman as the head and Koricancha corresponding to the feline's genitalia. We hired a local guide who was very friendly and knowledgable about this amazing work of art.
