Ollantaytambo (Quechua: Ullantaytampu) is a town and an Inca archaeological site in southern Peru some 72 kilometres (45 mi) by road northwest of the city of Cusco. It is located at an altitude of 2,792 metres (9,160 ft) above sea level in the district of Ollantaytambo, province of Urubamba, Cusco region. During the Inca Empire, Ollantaytambo was the royal estate of Emperor Pachacuti who conquered the region, built the town and a ceremonial center. At the time of the Spanish conquest of Peru it served as a stronghold for Manco Inca Yupanqui, leader of the Inca resistance. Nowadays, located in what is called the Sacred Valley of the Incas, it is an important tourist attraction on account of its Inca ruins and its location en route to one of the most common starting points for the four-day, three-night hike known as the Inca Trail.
