Ollantaytambo is a town and an Inca archaeological site in southern Peru some 72 km (45 mi) by road northwest of the city of Cusco. It is located at an altitude of 2,792 m (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, and 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. Located in the Sacred Valley of the Incas, it is now 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.

The Inca Empire, called Tawantinsuyu by its subjects, was the largest empire in pre-Columbian America. The administrative, political, and military center of the empire was in the city of Cusco. The Inca civilization rose from the Peruvian highlands sometime in the early 13th century. The Spanish began the conquest of the Inca Empire in 1532 and by 1572, the last Inca state was fully conquered.
