The Complete History of Machu Picchu: Lost City of the Incas

Hidden high in the cloud forests of the Andes Mountains, Machu Picchu stands as one of the world’s most enduring archaeological mysteries.

Often referred to as the "Lost City of the Incas," this 15th-century citadel tells a story of imperial power, sophisticated engineering, and spiritual reverence. But how did this breathtaking wonder come to be, and why was it abandoned? Let’s journey through the complete history of Machu Picchu.

The Rise of the Inca Empire

Before Machu Picchu was even conceived, the Inca Empire—the largest empire in pre-Columbian America—was flourishing. Centered in Cusco, the empire expanded rapidly during the early 1400s under the leadership of Pachacuti Inca Yupanqui, a visionary emperor often credited with transforming the Inca kingdom into an empire.

Pachacuti was more than a conqueror; he was a builder and a planner. He commissioned grand cities, an extensive road system, and luxurious royal estates. Machu Picchu was likely one of these royal retreats, constructed for Pachacuti himself.

The Construction of Machu Picchu (c. 1450)

Built around 1450, Machu Picchu was a marvel of engineering and architecture. Its location—perched between the peaks of Machu Picchu and Huayna Picchu—was both strategic and sacred. The Incas believed the mountains were powerful spiritual entities.

Using no wheels or iron tools, Inca engineers employed a technique called ashlar, fitting stones so precisely together that not even a knife blade could slip between them. They developed complex agricultural terraces, sophisticated drainage systems, and religious shrines aligned with astronomical events.

At its height, Machu Picchu could have supported around 500 to 750 inhabitants, mainly members of the Inca elite, priests, and servants.

Purpose and Significance

The true purpose of Machu Picchu is still debated, but scholars agree on several key possibilities:

Royal Estate: A luxurious retreat for Emperor Pachacuti and his court.
Religious Site: A spiritual center aligned with sacred mountains and celestial bodies.
Agricultural Experiment Station: The terraces may have been used to test crops in different microclimates.

Its design reflects deep respect for the surrounding landscape, blending human architecture with natural forms in a harmonious relationship.

The Mysterious Abandonment (c. 1572)

Machu Picchu was likely abandoned just over a century after its construction. The reasons remain speculative:

Spanish Conquest: While the Spanish never discovered Machu Picchu, the chaos following the conquest of the Inca Empire disrupted the networks and resources necessary to sustain remote estates.
Disease and Decline: European diseases decimated indigenous populations, possibly leading to depopulation.
Internal Conflict: Civil wars among the Incas could have led to the site's abandonment.

Whatever the cause, Machu Picchu faded from memory, hidden by thick jungle for nearly 400 years.

Rediscovery by Hiram Bingham (1911)

Although local indigenous people knew of Machu Picchu, it remained unknown to the outside world until Hiram Bingham, a Yale University historian, arrived in 1911. Guided by a local farmer and a young boy, Bingham was led to the overgrown ruins.
Amazed by what he found, Bingham began excavations with the support of Yale and National Geographic, bringing Machu Picchu to international fame. Unfortunately, Bingham controversially removed thousands of artifacts to Yale, sparking a long-running dispute with Peru that was finally settled in 2011, when many items were returned.

Machu Picchu Today: A World Wonder

In 1983, UNESCO declared Machu Picchu a World Heritage Site, recognizing its cultural and natural significance. In 2007, it was voted one of the New Seven Wonders of the World.
Today, Machu Picchu is one of the most visited tourist destinations globally, attracting over a million visitors each year. Strict regulations now aim to preserve its fragile structures and ecosystems for future generations.
