Chachapoyas in the north central highlands of Peru
This fortress is the largest stone structure of South America. It contains more than 450 stone houses. It is located on a mountain higher than Machu Picchu, is much older than the Inca Empire. This Machu Picchu of the North was found in better condition than the one in the South. The Kuelap complex remains relatively unknown in this remote zone, which only thirty years ago took two months to walk out to from the nearest road. The fortress is filled with a million air plants, bromeliads and orchids, high on a mountain top, in this mysterious cloud forest.
