Machu Picchu

Built c. 1450 under Pachacuti at the height of Inca power. Abandoned during Spanish conquest. Hidden for four centuries. Brought to world attention in 1911.

Around 1438, a regional conflict transformed Inca history. The Chankas people attacked Cusco; the prince who would become Pachacuti rallied defense and achieved victory. His father had fled; Pachacuti stayed. The victory launched a dynasty and an empire. In the decades that followed, Pachacuti transformed the Inca from a regional power into the largest empire in pre-Columbian America. Among his constructions was Machu Picchu—a royal estate and sacred sanctuary positioned in a landscape of apus and sacred waters. The site served multiple functions that the Inca did not separate as we do: residence for elite, temple for ceremony, observatory for astronomy, agricultural experiment station. Perhaps a thousand people lived here at its height. Then came the Spanish. By the 1530s, the empire was collapsing—civil war, European disease, conquistador violence. Machu Picchu was abandoned. The reasons remain unclear: perhaps the disruption of state support systems, perhaps depopulation, perhaps the routes that sustained it becoming impossible. Whatever the cause, the jungle closed in. For four centuries, only farmers in the valley knew the overgrown ruins existed. In 1911, Hiram Bingham—American academic, explorer, self-promoter—was led to the site by Melchor Arteaga, a local farmer. Others had visited before; Bingham brought the world. His photographs and writings made Machu Picchu an icon. Subsequent archaeology revealed what Bingham had not seen: burials, offerings, astronomical alignments, a sacred landscape made stone.
