Machu Picchu

Machu Picchu is a 15th-century Inca citadel set high in the Andes Mountains of Peru, believed to have served as a royal estate and sacred religious site for Inca rulers. [1][3]

Built during the reign of Inca emperor Pachacuti (c. 1438-1472 CE), Machu Picchu was abandoned approximately a century later during the Spanish conquest. The site was largely unknown to the outside world until American historian Hiram Bingham brought it to international attention in 1911. [1][2]

The site includes temples, terraces, and water channels that reflect Inca cosmology and their reverence for natural features including mountains (apus), the sun (Inti), and water. The Intihuatana stone is believed to have served as an astronomical observatory and ritual stone. The Temple of the Sun and the Room of the Three Windows are among the most important ceremonial structures. [1][2]

Machu Picchu is a UNESCO World Heritage Site and one of the New Seven Wonders of the World. Visitor numbers are limited to protect the site. [3][1]

Machu Picchu is reached today by railway and by the Inca Trail, a multi-day walk past subsidiary ruins that culminates at the citadel, with daily visitor numbers capped to protect the site. It draws travelers and students of Andean heritage from around the world. [1][3]

The citadel combines temples, palaces, terraces, and water channels in finely fitted stonework set dramatically on a high Andean ridge. The Intihuatana stone, the Temple of the Sun, and the Room of the Three Windows are among its principal ceremonial structures. [1][2]

Built in the fifteenth century as a royal estate and sacred center under the emperor Pachacuti, Machu Picchu reflects Inca reverence for mountains (apus), the sun deity Inti, and water. Abandoned around the time of the Spanish conquest, it was brought to international attention in 1911. [1][2]
