It’s incredible to witness the extraordinary architectural works of the Inca Empire, covering an area of 32,592 hectares, with a large number of ancient ruins still standing today. The Inca masons used a technique of fitting granite stones perfectly together without mortar, called Ashlar. These stones were cut using bronze tools and harder stones found in nearby quarries were used to pound the stones into shape, ensuring these structures were strong enough to withstand earthquakes and heavy rain. Smaller stones were transported by llama, whilst the heavier stones were dragged by men using rope. Some of the best examples of the Machu Picchu architecture include The Temple of the Sun, The Royal Tomb, The Sacred Plaza and The Pyramid of Intiwuatana.
