Machu Picchu is one of the new seven wonders of the world.
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 are fit so well that not even the blade of a knife would fit between them.
