2. Geographical Context: A Fortress in the Sky
Machu Picchu’s unique location played a crucial role in its construction and purpose. Situated in the Cordillera de Vilcabamba, about 50 miles (80 km) northwest of Cuzco, Peru, the city is perched on a narrow saddle between two peaks, Machu Picchu (“Old Peak”) and Huayna Picchu (“New Peak”), overlooking the Urubamba River valley at an elevation of 7,710 feet (2,350 meters).
2.1. Strategic Importance of the Location
The strategic placement of Machu Picchu offered several advantages:
- Defense: The city’s high altitude and remote location provided a natural defense against potential invaders. The steep slopes and surrounding mountains made it difficult to access, ensuring a secure and protected environment.
- Control: The site’s commanding view of the Urubamba River valley allowed the Incas to monitor and control the surrounding area, including trade routes and agricultural lands.
- Resources: The location provided access to fresh water sources, fertile land for agriculture, and valuable resources such as stone and timber for construction.

2.2. Geological Challenges and Engineering Marvels
Building Machu Picchu in such a challenging environment required extraordinary engineering skills. The Incas had to overcome several geological obstacles:
- Steep Slopes: Constructing structures on steep slopes required extensive terracing and retaining walls to prevent landslides and ensure stability.
- Water Management: The site’s location meant that it was prone to heavy rainfall, necessitating the development of sophisticated drainage systems to prevent flooding and erosion.
- Earthquake Resistance: Peru is located in an active seismic zone, so the Incas had to design buildings that could withstand earthquakes. They achieved this by using a technique called “ashlar masonry,” where stones were precisely cut and fitted together without mortar, allowing the walls to flex and absorb seismic energy.
3. Historical Background: The Rise of the Inca Empire
To understand why Machu Picchu was built, it’s essential to consider the historical context of the Inca Empire. The Inca civilization emerged in the 15th century, rapidly expanding from its heartland in Cuzco to become the largest empire in pre-Columbian America.
3.1. Pachacuti Inca Yupanqui: The Visionary Ruler
Pachacuti Inca Yupanqui, who reigned from c. 1438 to 1471, is widely believed to have been the driving force behind the construction of Machu Picchu. Pachacuti was a brilliant military leader, statesman, and urban planner who transformed Cuzco from a modest village into a magnificent imperial capital.
3.2. Expansion and Consolidation of Power
Under Pachacuti’s leadership, the Inca Empire expanded rapidly, conquering neighboring tribes and establishing control over vast territories. To consolidate their power, the Incas built an extensive network of roads, administrative centers, and religious sites throughout their empire.
3.3. Architectural and Engineering Achievements
The Incas were renowned for their architectural and engineering skills. They built impressive structures using locally available materials, such as stone, adobe, and thatch. Their construction techniques were characterized by precision, durability, and a deep understanding of the natural environment.
4. Theories on the Purpose of Machu Picchu
The exact purpose of Machu Picchu remains a subject of debate among scholars. However, several theories have been proposed, each supported by varying degrees of evidence.
4.1. Royal Estate or Retreat
One of the most widely accepted theories is that Machu Picchu served as a royal estate or retreat for Pachacuti Inca Yupanqui and his successors. This theory is based on several factors:
- Location: The site’s secluded location, away from major population centers, suggests that it was intended as a private retreat for the Inca elite.
- Architecture: The presence of elaborate palaces, temples, and residential quarters indicates that Machu Picchu was designed to accommodate royalty and their entourage.
- Artifacts: The discovery of high-quality ceramics, textiles, and metalwork at the site suggests that it was inhabited by people of high status.

4.2. Religious Sanctuary
Another theory is that Machu Picchu was a religious sanctuary, dedicated to the worship of the sun god Inti and other important Inca deities.
- Temples and Shrines: The presence of several temples and shrines at the site, including the Temple of the Sun and the Intihuatana (Hitching Post of the Sun), supports the idea that Machu Picchu was an important religious center.
- Astronomical Alignment: The alignment of certain structures with the sun during solstices and equinoxes suggests that the Incas had a deep understanding of astronomy and incorporated it into their religious practices.
- Sacred Landscape: The site’s location amidst towering mountains and the sacred Urubamba River valley may have been considered a particularly auspicious and spiritually charged place.
4.3. Agricultural Research Center
Some scholars propose that Machu Picchu served as an agricultural research center, where the Incas experimented with different crops and farming techniques to improve food production.
- Terraces: The extensive network of agricultural terraces at the site suggests that farming was an important activity.
- Microclimates: The variety of microclimates within Machu Picchu may have allowed the Incas to cultivate a wide range of crops.
- Water Management: The sophisticated irrigation systems at the site demonstrate the Incas’ expertise in water management and their commitment to maximizing agricultural output.
4.4. Military Outpost
Although Machu Picchu’s primary function was likely not military, it may have served as a strategic outpost to protect the surrounding region from potential threats.
- Defensive Location: The site’s high altitude and remote location provided a natural defense against invaders.
- Watchtowers: The presence of watchtowers and fortified structures at the site suggests that it was used for surveillance and defense.
- Proximity to Trade Routes: Machu Picchu’s location near important trade routes may have allowed the Incas to monitor and control the flow of goods and people in the region.
5. Unraveling the Mysteries: Key Features of Machu Picchu
Machu Picchu is a complex and multifaceted site, with numerous features that offer clues to its purpose and significance.
5.1. The Intricate Stonework
The Incas’ mastery of stonework is evident throughout Machu Picchu. The stones were precisely cut and fitted together without mortar, creating walls that have withstood centuries of earthquakes and weather.
5.2. The Temple of the Sun
The Temple of the Sun, also known as the Sacred Rock or the Mausoleum, is one of the most important religious structures at Machu Picchu. It is centered on an inclined rock mass with a small grotto, and its walls are constructed of finely cut stone.
5.3. The Intihuatana Stone
The Intihuatana, or Hitching Post of the Sun, is a unique ceremonial sundial carved from a single piece of stone. It is believed to have been used to track the movement of the sun and mark important dates in the Inca calendar.
5.4. The Three Windows Temple
The Temple of the Three Windows is a hall with three trapezoidal windows, the largest known in Inca architecture. The windows are aligned with the rising sun during the summer solstice, suggesting that they were used for astronomical observations and religious ceremonies.
5.5. The Agricultural Terraces
The agricultural terraces at Machu Picchu are a testament to the Incas’ ingenuity and their commitment to sustainable farming practices. The terraces were carefully designed to prevent erosion, conserve water, and maximize crop yields.
6. The Abandonment of Machu Picchu
The reasons for the abandonment of Machu Picchu remain a mystery. However, several theories have been proposed:
6.1. Spanish Conquest
The Spanish conquest of the Inca Empire in the 16th century may have led to the abandonment of Machu Picchu. As the Spanish advanced, the Incas may have fled to remote areas to escape their rule.
6.2. Smallpox Epidemic
A smallpox epidemic that swept through the Inca Empire in the 16th century may have decimated the population of Machu Picchu, making it impossible to maintain the city.
6.3. Internal Conflicts
Internal conflicts within the Inca Empire may have led to the abandonment of Machu Picchu. As rival factions vied for power, the city may have become caught in the crossfire.
6.4. Lack of Resources
A shortage of resources, such as water or food, may have forced the inhabitants of Machu Picchu to abandon the city in search of more sustainable living conditions.
7. The Rediscovery of Machu Picchu
Machu Picchu remained largely unknown to the outside world until its rediscovery in 1911 by Hiram Bingham, an American historian and explorer.
