Machu Picchu was abandoned by the Inca civilization during the Spanish conquest in the 16th century and was largely forgotten. It is an ancient Inca citadel located in the Andes Mountains of Peru. It is one of the most famous and well-preserved archaeological sites in the world, and it is often referred to as the “Lost City of the Incas.” The site is known for its remarkable Inca stone construction, with precisely cut and fitted stones that fit together without the use of mortar. The architecture includes temples, terraces, plazas, and residential buildings. The mystery surrounding the site’s abandonment remains, although a lack of water is one possible explanation. Today, the layout of Machu Picchu impresses visitors, featuring terraced farms, aqueduct systems, plazas, living areas, terraces, a cemetery, and the main buildings, all interconnected by stone walkways.
