Machu Picchu Peru - a History Lesson

Everything about Machu Picchu makes you marvel that it ever came to exist. The lost city of the Incas is built on a saddle-shaped ridge slung between two giant peaks. Near vertical slopes drop away on either side, down to a massive bend in the Urubamba River. Machu Picchu was constructed around 1450, at the height of the Inca Empire. It was abandoned less than 100 years later. It is likely that most of its inhabitants were wiped out by smallpox before the Spanish conquistadores arrived.

Machu Picchu was hidden by jungle since the 16th century until it was rediscovered in 1911.

Machu Picchu is a UNESCO World Heritage site.

As Peru’s most visited tourist attraction and major revenue generator, it is continually threatened by economic and commercial forces. In the late 1990s, the Peruvian government granted concessions to allow the construction of a cable car to the ruins and development of a luxury hotel, including a tourist complex with boutiques and restaurants. These plans were met with protests from scientists, academics and the Peruvian public, worried that the greater numbers of visitors would pose tremendous physical burdens on the ruins.
A growing number of people visit Machu Picchu (400,000 in 2003). For this reason, there were protests against a plan to build a further bridge to the site and a no-fly zone exists in the area .UNESCO is considering putting Machu Picchu on its list of endangered World Heritage Sites.
The population of Machu Picchu is believed to have numbered over a thousand and the people were so distant from other settlements that they would have produced much of their own food. This accounts for the intricately terraced fields, which have survived remarkably intact thanks to the care and skill that went into their construction. Maize and potatoes were grown, and advanced irrigation techniques were used to ensure that rainwater didn’t just run off down the hill to the Urumbamba River far below.

Most of the construction in Machu Picchu uses the classic Inca architectural style of polished dry-stone walls of regular shape. The Incas were masters of this technique, called ashlar, in which blocks of stone are cut to fit together tightly without mortar. The Incas were among the best stone masons the world has seen, and many junctions in the central city are so perfect that not even a knife fits between the stones.
Other Inca buildings have been built using mortar, but by Inca standards that was quick, shoddy construction. Peru is a highly seismic land, and mortar-free construction was more earthquake-resistant than using mortar. Inca walls show numerous subtle design details that would prevent them from collapsing in an earthquake. Doors and windows are trapezoidal and tilt inward from bottom to top, corners are usually rounded, inside corners often incline slightly into the rooms, and "L" shaped blocks are often used to tie outside corners together. Walls do not rise straight from top to bottom but are offset slightly from row to row. As a result, Machu Picchu is a city that has stood up well to earthquakes over the years.

The Incas never used the wheel in any practical manner. How they moved and placed enormous blocks of stones is a mystery, although the general belief is that they used hundreds of men to push the stones up inclined planes. A few of the stones still have knobs on them that could have been used to lever them into position. After they were placed, the Incas would have sanded the knobs away.

The space is composed of 140 constructions including temples, sanctuaries, parks and residences (houses with thatched roofs). There are more than one hundred flights of stone steps – often completely carved from a single block of granite – and a great number of water fountains, interconnected by channels and water-drainages perforated in the rock, designed for the original irrigation system. Evidence has been found to suggest that the irrigation system was used to carry water from a holy spring to each of the houses in turn.

According to archaeologists, the urban sector of Machu Picchu was divided into three great districts: the Sacred District, the Popular District, to the south, and the District of the Priests and the Nobility.

Located in the first zone are the primary archaeological treasures: the Intihuatana, the Temple of the Sun and the Room of the Three Windows. These were dedicated to Inti, their sun god and greatest deity. The Popular District, or Residential District, is the place where the lower class people lived. It includes storage buildings and simple houses to live in.

In the royalty area, a sector existed for the nobility: a group of houses located in rows over a slope; the residence of the Amautas (wise persons) was characterized by its reddish walls, and the zone of the Ñustas (princesses) had trapezoid-shaped rooms. The Monumental Mausoleum is a carved statue with a vaulted interior and carved drawings. It was used for rites or sacrifices.

As part of their road system, the Inca built a road to Machu Picchu, the Inca Trail.
No one knows for sure why Machu Picchu was built. Some surmise that it was a royal or religious retreat for one of the Inca rulers. Certainly its remote location and altitude of nearly 2500 metres would seem to rule out any trade or military function. Whatever its use, the obvious effort that went into its construction indicates that it was considered important and held in high regard by those who created it.
