Frequently Asked Questions
When was Machu Picchu built and who constructed this ancient citadel?
Machu Picchu was built around 1450 CE during the reign of Inca emperor Pachacuti. The site was constructed by skilled Inca stonemasons and laborers who transported massive granite blocks up the steep mountain terrain. The citadel served as a royal estate and religious sanctuary for Inca nobility.
How did Hiram Bingham rediscover Machu Picchu in the early 20th century?
American historian Hiram Bingham reached Machu Picchu on July 24, 1911, guided by local Quechua people who knew of the ruins. He was searching for Vilcabamba, the last stronghold of the Incas, when he encountered the partially overgrown citadel. Bingham's photographs and reports brought international attention to the site, though local inhabitants had never truly lost knowledge of its existence.
What are the main theories about why the Incas abandoned Machu Picchu?
Scholars believe Machu Picchu was abandoned around 1572 during the Spanish conquest of the Inca Empire. The remote location may have made it difficult to supply and maintain during the political upheaval. Another theory suggests the site was abandoned earlier due to smallpox outbreaks that devastated Inca populations, making it impossible to maintain the complex agricultural terraces and stone structures.
