The Sectors and Constructions of Machu Picchu. The citadel of Machu Picchu is divided into two sectors: the agricultural (terracing) and the urban, where there are main squares, temples, palaces, storehouses, workshops, stairways, cables and water fountains which run through both sectors, which measure 20 and 10 hectares respectively. It is clear that the architectural design was based on Cuzco, the Capital of the Inca Empire. Machu Picchu was built according to its natural surroundings, with its constructions following the natural curves and dips and rises in the land. The archaeological excavation that took place after Bingham discovered the ruins showed the land was previously given granite foundations with little surrounding soil. The agricultural and urban sectors of Machu Picchu are split by a dry ditch, the result of a geographic fault line. The following describe the most important constructions in both sectors. http://ping.fm/RXDOR
