Ollantaytambo (called by locals Ollanta) is a town and an Inca archaeological site in southern Peru. This is where the Incas retreated after the Spanish took Cuzco. Much of the town is laid out in the same way as it was in Inca times. Today it is an important tourist attraction on account of its Inca buildings and as one of the most common starting points for the four-day, three-night hike known as the Inca Trail.
