For those who love to travel, Machu Picchu is far from being strange, because the mysterious Inca Empire was once very prosperous. Some people say it is the last Inca city to resist Spanish. It was built to represent the Inca mythology. A particular landscape, or it is to commemorate the sacred rivers and mountains surrounding it. It is also said that the city is a sacred monastery or a royal monastery. The specific construction reasons are not available. But this unforgettable grey ruin is still the pride of this pure white granite city in the cloud, this forgotten centuries of Inca wonders, located 2,400 meters in the Andes.
