Machu Picchu is one of the new seven wonders of the world.
It is a 15th-century Inca citadel, located in the Eastern Cordillera of southern Peru, on a 2,430-metre (7,970 ft) mountain ridge.
Most archaeologists believe that Machu Picchu was constructed as an estate for the Inca emperor Pachacuti (1438–1472).
Machu Picchu is often referred to as the “Lost City of the Incas” due to the belief that the Spanish never found the city when they conquered the Incan Empire in the 1500’s.
The granite rocks used to construct Machu Picchu were extremely heavy with some weighing over 55 tons, it was constructed with a technique called ashlar which involves stones being perfectly shaped so that a mortar is not needed. The stones fit so well that not even the blade of a knife would fit between them.
