The complex of Ollantaytambo, perched on a hilltop overlooking the town, features buildings such as the Temple of the Sun, the Mañaracay or Royal Chamber, the Incahuatana and the Princess' Baths.
The upper section os Ollantaytambo features a fortress made up of a series of carved stone terraces built to protect the valley from possible invasion by warring jungle tribes.
One of the best-preserved areas lies north of the Hanan Huacaypata square: an area of 15 blocks of houses built on top of carved stone walls.
