Machu Picchu is by far the best known destination in Peru but for some people it may come as a surprise that Machu Picchu was not the most important city for the Incas. The most important city for the Incas was by far Cusco (also written as Cuzco or Qosqo in Quechuea). It was here that all governmental power, religious leaders and astrologers where based and it was from here that the huge empire was being organized. The most important buildings in Cusco were the 14 Inca Palaces on what is now the Plaza de Armas and the site of Coricancha at what is nowadays called Sol Avenue.
