Cusco Adventure Tours
The original Inca city, said to have been founded in the eleventh century, was sacked by Pizarro in 1535. There are still remains, however, of the palace of the Incas, the Temple of the Sun, and the Temple of the Virgins of the Sun. Among the most noteworthy buildings of the city is the cathedral of Santo Domingo.
The major nearby Inca sites are Pachacuti’s presumed winter home, Machu Picchu (which can be reached by a lightly maintained Inca trail or the train) the “fortress” at Ollantaytambo, and the “fortress” of Sacsayhuaman, which is approximately two kilometers from Cusco.
Other less-visited ruins include Inca Wasi, the highest of all Inca sites at 3,980 meters (13,134 feet), Old Vilcabamba (the capital of the Inca after the capture of Cuzco), the sculpture garden at Chulquipalta (aka Chuquipalta, Ñusta España, The White Rock, Yurak Rumi), as well as Huillca Raccay, Papallacta, Choquequirao, and Moray, among others.
