The agricultural terraces, which form a distinctive part of Machu Picchu’s landscape, served multiple purposes. They prevented soil erosion, created microclimates for diverse crops, and formed part of the site’s sophisticated water management system. The terraces were constructed with layers of rock, gravel, and soil that allowed for efficient drainage and soil aeration.
Astronomical alignments: intihuatana stone and temple of the sun
Machu Picchu’s builders incorporated celestial alignments into the site’s design, reflecting the Incas’ deep connection to astronomical phenomena. The Intihuatana Stone, often referred to as the “Hitching Post of the Sun,” is believed to have been used as a solar clock or calendar.
The Temple of the Sun, with its distinctive curved wall, aligns perfectly with the summer solstice. During this event, sunlight enters through a specific window, illuminating the temple’s ceremonial stone. These alignments suggest that Machu Picchu played a significant role in Inca astronomical observations and religious ceremonies.
Unresolved mysteries of machu picchu’s purpose and abandonment
Despite extensive research, the exact purpose of Machu Picchu and the reasons for its abandonment remain subjects of debate among scholars. Various theories have been proposed, each offering a different perspective on the citadel’s role in Inca society.

One prevalent theory suggests that Machu Picchu served as a royal estate for the Inca emperor Pachacuti. This hypothesis is supported by the site’s architectural grandeur and its strategic location. The presence of high-status ceramics and exotic goods further reinforces the idea of Machu Picchu as an elite retreat.
However, recent archaeological evidence has complicated this theory. The discovery of a diverse range of artifacts and residential areas suggests that Machu Picchu may have had a more varied population than previously thought, including artisans, priests, and possibly even temporary workers.
The debate: religious sanctuary vs. military stronghold
Another ongoing debate centers on whether Machu Picchu primarily served as a religious sanctuary or a military stronghold. The presence of numerous temples and ritual spaces supports the idea of a sacred site. The Intihuatana Stone and other astronomically aligned structures further emphasize the citadel’s religious significance.
Conversely, the site’s defensible position and the presence of what appear to be guardhouses have led some researchers to argue for a military function. The truth may lie in a combination of these roles, with Machu Picchu serving multiple purposes within the Inca Empire.
Llaqta of machu picchu: evidence for an administrative centre
Recent research has proposed that Machu Picchu may have functioned as a llaqta , or administrative center, managing resources and labor in the surrounding region. This theory is supported by evidence of large-scale food storage facilities and the presence of diverse craft production areas.
The llaqta hypothesis suggests that Machu Picchu played a crucial role in coordinating economic activities, religious ceremonies, and political functions for the broader area. This multifaceted role could explain the site’s complex layout and diverse architectural features.
Hypotheses on the citadel’s sudden abandonment
The abrupt abandonment of Machu Picchu remains one of its most perplexing mysteries. Several hypotheses have been put forward to explain this sudden desertion:
- Spanish conquest and the collapse of the Inca Empire
- Outbreak of disease, possibly smallpox introduced by European contact
- Internal political strife within the Inca leadership
- Environmental factors such as drought or earthquakes
- Ritual abandonment as part of Inca religious practices
Each of these theories has its merits and challenges, and the true reason for Machu Picchu’s abandonment may involve a combination of factors. Ongoing research and new archaeological techniques continue to provide fresh insights into this enduring mystery.
