Located at an altitude of 2,792 meters (9,160 feet) in Peru’s Sacred Valley, Ollantaytambo was rebuilt in the 15th century by Emperor Pachacuti, who turned it into a royal estate, enhancing its architecture and agricultural systems. During the Spanish conquest, it served as a stronghold of Inca resistance under Manco Inca Yupanqui, who defeated a Spanish contingent there in 1536 before retreating.
