Qhapac Ñan, The Great Inca Trail - Peru - stock photo

This site is an extensive Inca communication, trade and defence network of roads covering 30,000 km. Constructed by the Incas over several centuries and partly based on pre-Inca infrastructure, this extraordinary network through one of the world’s most extreme geographical terrains linked the snow-capped peaks of the Andes – at an altitude of more than 6,000 m – to the coast, running through hot rainforests, fertile valleys and absolute deserts. It reached its maximum expansion in the 15th century, when it spread across the length and breadth of the Andes.
