This famous citadel combines the visual and spiritual force of magnificent natural scenery with a historic sanctuary, and was recently recognised as one of the 'New 7 Wonders of the World'. The ruins themselves are situated on the eastern slope of Machu Picchu in two separate areas - agricultural and urban. The latter includes the civil sector (dwellings and canalisations) and the sacred sector (temples, mausoleums, squares and royal houses). The history of Machu Picchu says that only the Inca and his noblemen, priests, priestesses and chosen women (Acllas) had free access to the premises of the Machu Picchu sanctuary.
