Machu Picchu is an Incan citadel located in the Andes Mountains in Peru, and is considered one of the New Seven Wonders of the World.
Machu Picchu was rediscovered in 1911 by American explorer Hiram Bingham and has since become a major tourist attraction.
The citadel is made up of more than 200 structures, including temples, terraces, and plazas, and is believed to have been a sacred site for the Inca people.
Machu Picchu was built using a technique known as "ashlar masonry," in which stones are cut to fit together perfectly without the use of mortar.
Machu Picchu is believed to have been used for religious and ceremonial purposes, and many of the structures are aligned with astronomical events.
Machu Picchu is a UNESCO World Heritage Site and is considered a symbol of Inca civilization and Andean culture.
