Santuário Arqueológico de Ollantaytambo

Ollantaytambo is an Inca archaeological site and living town in Peru's Sacred Valley, at 2,792 m elevation. Built around 1450 by Emperor Pachacuti as a royal estate, it features 17 imposing agricultural terraces leading to a fortress crowned by the Temple of the Sun, composed of six enormous pink granite monoliths. In 1536-37, Manco Inca used the fortress as his stronghold, defeating Spanish forces by flooding the valley floor in one of the rare indigenous victories of the conquest. It is the only Inca town still continuously inhabited, with original stone streets and canal systems preserved alongside colonial-era architecture.
