Machu Picchu amazing place to visit.

Machu Picchu is a 15th-century Inca citadel located in the Eastern Cordillera of southern Peru on a 2,430-meter (7,970 ft) mountain ridge. Often referred to as the "Lost City of the Incas", it is the most familiar icon of the Inca Empire. The Urubamba River flows past it, cutting through the Cordillera and creating a canyon with a tropical mountain climate.

The Inca civilization had no written language and following the first encounter by the Spanish soldier Baltasar Ocampo. As far as historical knowledge extends, there are no existing written records detailing the site during its period of active use.

 Machu Picchu was built in the classical Inca style, with polished dry-stone walls. Its three primary structures are the Temple of the Sun, the Temple of the Three Windows, and the Intihuatana. Most of the outlying buildings have been reconstructed in order to give visitors a better idea of how they originally appeared.

By 1976, 30 percent of Machu Picchu had been restored and restoration continues. Most recent archaeologists believe that Machu Picchu was constructed as an estate for the Inca emperor Pachacuti (1438–1472). The Incas built the estate around 1450 but abandoned it a century later, at the time of the Spanish conquest. According to the new AMS radiocarbon dating, it was occupied from c. 1420–1532.

Machu Picchu was declared a Peruvian Historic Sanctuary in 1982 and a UNESCO World Heritage Site in 1983. In 2007, Machu Picchu was voted one of the New Seven Wonders of the World in a worldwide internet poll.
