Imagine the surprise of Hiram Bingham, when he discovered the city of Machu Picchu in 1911. This almost intact entire Inca city is perched on a rocky outcrop at an altitude of almost 2,400m. Now the emblem of Peru, it is also the object of continuing discussions and questions. What role did it play? Why did the Spanish never loot this city? From the terraced crops to the working-class and imperial residences, without forgetting the places of worship and astronomic observatories, the site continues to intrigue and mystify, but above all to enchant the visitor.
