Machu Picchu: the Lost City of the Incas

Introduction

High in the cloud forests of the Peruvian Andes, balanced on a narrow ridge between two jagged mountain peaks, sits one of the most extraordinary human achievements in the history of the world. Machu Picchu, the ancient Inca citadel that has come to symbolize the genius, ambition, and spiritual depth of pre-Columbian South America, draws visitors from every corner of the globe to gaze upon its stone plazas, terraced hillsides, and precisely fitted walls. It is simultaneously a monument to human engineering, a sacred ceremonial landscape, a royal retreat of unimaginable splendor, and a mystery that continues to reveal new secrets to the archaeologists and historians who have devoted their lives to its study.

For centuries after its apparent abandonment, Machu Picchu lay hidden from the wider world beneath a dense blanket of jungle vegetation, known only to the scattered local farmers who tended their fields among its terraces. When the American explorer Hiram Bingham III arrived at the site on July 24, 1911, guided by a local child up a steep jungle path, he encountered something that would change the course of his life, reshape the world's understanding of Inca civilization, and launch a chain of events whose reverberations are still felt in debates over cultural heritage, indigenous rights, and the ethics of archaeological exploration. Yet even the term "rediscovery" applied to that July morning carries with it layers of controversy and contested meaning that the story of Machu Picchu demands we examine honestly.

This article explores the full breadth of what is known about Machu Picchu: its geography and physical setting, the civilization that built it, the extraordinary construction techniques that allowed its builders to raise massive stone structures on a steep Andean ridge without mortar or iron tools, the key buildings and sacred spaces that make up the site, the question of who lived there and why, the circumstances of its abandonment and subsequent concealment from the Spanish conquistadors, the complex history of its modern rediscovery and the long legal battle over the thousands of artifacts removed from the site, and the profound challenges that the twenty-first century presents to the site's preservation. At every turn, the story of Machu Picchu is a story about the intersection of past and present, about what societies choose to remember and what they allow to be forgotten, and about the human impulse to seek meaning in the traces left behind by those who came before.

Location and Geography

Machu Picchu occupies one of the most spectacular and improbable settings of any human settlement on Earth. The site sits at an elevation of approximately 7,970 feet (2,430 meters) above sea level, perched atop a narrow mountain ridge in the Urubamba River valley of south-central Peru. It lies roughly 50 miles (80 kilometers) northwest of the city of Cusco, the former capital of the Inca Empire, in the region of the Andes known as the Cordillera de Vilcabamba. The citadel is flanked on two sides by the dramatic peaks from which it takes its name: to the south rises the broader summit of Machu Picchu, meaning "Old Peak" in the Quechua language, while to the north soars the sharper, more imposing spike of Huayna Picchu, meaning "Young Peak," which provides the iconic backdrop to virtually every photograph of the site. Thousands of feet below the ridge, the Urubamba River, known in Inca times as the Vilcanota or Willkamayu, meaning "sacred river," winds in an enormous bend around three sides of the mountain, carving through a deep gorge whose walls are draped in tropical vegetation.

The physical location of Machu Picchu places it at the meeting point of two dramatically different ecological zones. To the west and east lie the dense, warm, humid cloud forests of the high Amazon basin, where mist rolls in daily from the lowlands and drapes the peaks and ridges in perpetual moisture. To the south stretches the dry, cold highland plateau of the Andes, where the ancient Inca capital of Cusco sits in a broad valley. This position at the boundary between ecosystems was not accidental. The Incas were deeply attentive to the natural world and understood the agricultural, economic, and spiritual significance of controlling land that bridged the highlands and the tropical lowlands. The region around Machu Picchu, known as the montaña, offered access to exotic tropical products unavailable in the high Andes, including coca leaves, exotic birds whose feathers were prized for ceremonial use, and a variety of medicinal and edible plants.
