Machu Picchu

Machu Picchu ("Old mountain") is a pre-Columbian Inca site located 2,400 meters (7,875 ft) above sea level. It is situated on a mountain ridge above the Urubamba Valley in Peru, which is 80 km (50 mi) northwest of Cusco. Often referred to as "The Lost City of the Incas", Machu Picchu is probably the most familiar symbol of the Inca Empire.

The Incas started building the estate around AD 1400 but it was abandoned as an official site for the Inca rulers a century later at the time of the Spanish conquest of the Inca Empire. Although known locally, it was unknown to the outside world before being brought to international attention in 1911 by the American historian Hiram Bingham. Since then, Machu Picchu has become an important tourist attraction.

Machu Picchu was declared a Peruvian Historical Sanctuary in 1981 and a UNESCO World Heritage Site in 1983. Since it was not plundered by the Spanish when they conquered the Incas, it is especially important as a cultural site and is considered a sacred place.

Machu Picchu was built in the classical Inca style, with polished dry-stone walls. Its primary buildings are the Intihuatana, the Temple of the Sun, and the Room of the Three Windows. These are located in what is known by archaeologists as the Sacred District of Machu Picchu. In September 2007, Peru and Yale University reached an agreement regarding the return of artifacts which Hiram Bingham had removed from Machu Picchu in the early twentieth century.

Machu Picchu was constructed around 1460, 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. Hiram Bingham, the credited discoverer of the site, along with several others, originally hypothesized that the citadel was the traditional birthplace of the Inca people or the spiritual center of the "Virgins of the Suns".

The Citadel

Another theory maintains that Machu Picchu was Inca "llacta": a settlement built to control the economy of the conquered regions. It may also have been built as a prison for a select few who had committed heinous crimes against Inca society. Research conducted by scholars, such as John Rowe and Richard Burger, has convinced most archaeologists that rather than a defensive retreat, Machu Picchu was an estate of the Inca emperor, Pachacuti. In addition, Johan Reinhard presented evidence that the site was selected based on its position relative to sacred landscape features. One such example is its mountains, which are purported to be in alignment with key astronomical events.

Although the citadel is located only about 80 kilometers (50 miles) from Cusco, the Inca capital, it was never found and consequently not plundered and destroyed by the Spanish, as was the case with many other Inca sites. Over the centuries, the surrounding jungle grew over the site, and few knew of its existence.

On July 24, 1911, Machu Picchu was brought to the attention of scholars by Hiram Bingham, an American historian then employed as a lecturer at Yale University. He was led there by locals who frequented the site. Bingham undertook archaeological studies and completed a survey of the area. Bingham coined the name "The Lost City of the Incas", which was the title of his first book. He never gave any credit to those who led him to Machu Picchu, mentioning only "local rumor" as his guide.

Bingham had been searching for the city of Vitcos, the last Inca refuge and spot of resistance during the Spanish conquest of Peru. In 1911, after years of previous trips and explorations around the zone, he was led to the citadel by Quechuans. These people were living in Machu Picchu, in the original Inca infrastructure. Even though most of the original inhabitants had died within a century of the city's construction, a small number of families survived so by the time the site was 'discovered' in 1911, there were still mummies (mostly women) in Machu Picchu and some families still living on the site. Bingham made several more trips and conducted excavations on the site through 1915. He wrote a number of books and articles about the discovery of Machu Picchu in his lifetime.

Simone Waisbard, a long-time researcher of Cusco, claims that Enrique Palma, Gabino Sanchez, and Agustin Lizarraga left their names engraved on one of the rocks at Machu Picchu on July 14, 1901. This would mean that they 'discovered' it long before Bingham did in 1911. Likewise, in 1904, an engineer named Franklin supposedly spotted the ruins from a distant mountain. He told Thomas Paine, an English Plymouth Brethren Christian missionary living in the region, about the site, Paine's family members claim. In 1906, Paine and another fellow missionary named Stuart E McNairn (1867-1956) supposedly climbed up to the ruins.

In 1913, the site received significant publicity after the National Geographic Society devoted their entire April issue to Machu Picchu. In 1981 an area of 325.92 square kilometers surrounding Machu Picchu was declared a "Historical Sanctuary" of Peru. In addition to the ruins, this area includes a large portion of the regional landscape, rich with flora and fauna.

Machu Picchu was designated as a World Heritage Site in 1983 when it was described as "an absolute masterpiece of architecture and a unique testimony to the Inca civilization". On July 7, 2007, Machu Picchu was voted as one of New Open World Corporation's New Seven Wonders of the World. As a result of environmental degradation resulting from the impacts of tourism, uncontrolled development in the nearby town of Aguas Calientes (including a poorly-sited tram to ease visitor access), and the construction of a bridge across the Vilcanota River in defiance of a court order and government protests (which would most likely bring even more tourists to the site), the World Monuments Fund placed Machu Picchu on its 2008 Watch List of the 100 Most Endangered Sites in the world.


Machu Picchu is 70 kilometers northwest of Cusco, on the crest of the mountain Machu Picchu, located about 2,350 meters (7,710 ft) above sea level. It is one of the most important archaeological centers in South America and the most visited tourist attraction in Peru.

From the top, at the cliff of Machu Picchu, there is a vertical rock face of 600 meters ending at the foot of the Urubamba River. The location of the city was a military secret because its deep precipices and mountains were an excellent natural defense. The Inca Bridge, an Inca rope bridge across the Urubamba River in the Pongo de Mainique, provided a secret entrance for the Inca army. Another Inca bridge to the west of Machu Picchu, the trunk bridge, has a section across a cliff face with a 6 metres (20 ft) gap in it which could be bridged by two tree trunks. If the trees were removed, it would leave a 570 metres (1,900 ft) fall to the base of the cliffs to discourage invaders. It is above Urubamba Valley.

The city sits in a saddle between two mountains, with a commanding view down two valleys and a nearly impassable mountain at its back. It has a water supply from springs that cannot easily be blocked, and enough land to grow food for about four times as many people as actually lived there. The hillsides leading to it have been terraced, not only to provide more farmland to grow crops, but to steepen the slopes which invaders would have to ascend. There are two high-altitude routes from Machu Picchu across the mountains back to Cuzco, one through the sun gate, and the other across the Inca bridge. Both could easily be blocked if invaders should approach along them. Regardless of its ultimate purpose, it is in a highly defendable position.


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.

Temple of the Sun

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 Nustas (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.

Inca Trail

As part of their road system, the Inca built a road to Machu Picchu. Today, tens of thousands of tourists walk the Inca Trail to Machu Picchu each year, acclimatizing at Cusco before starting on a two- to four-day journey on foot from the Urubamba valley up through the Andes mountain range.

Intihuatana Stone

Shamanic legends say that if you're a sensitive person and you rub your forehead against the stone you will see the spirit world. The Intihuatana stone is one of the many ritual stones in South America. They are arranged so they point directly at the sun during the winter solstice.

The Spanish did not find Machu Picchu until the 20th century so the Intihuatana Stone was not destroyed like many other ritual stones. It is also called "The Hitching Point of the Sun" because it was supposed to hold the sun in its place.

At midday on March 21st and September 21st the sun stands almost above the pillar creating no shadow at all. It is (as they said before) believed to be an astronomic clock built by the Incas.

The Intihuatana Stone was damaged in September 2000 when a 450 kg (1,000-pound) crane fell onto it, breaking off a piece of stone the size of a ballpoint pen.

In the 1980s, a large rock from Machu Picchu's central plaza was moved to a different location in order to create a helicopter landing zone. Helicopter landings were forbidden in the 1990s. Reports circulated in February 2008 that a company, Helicusco, was able to make tourist flights over Machu Picchu, but the situation is unclear.

Concerns Over Tourism

Machu Picchu is both a cultural and natural UNESCO World Heritage Site. Since its rediscovery in 1911, growing numbers of tourists have visited the site each year, with numbers exceeding 1.4 million in 2017. As Peru's most visited tourist attraction, and a major revenue generator, it is continually exposed to economic and commercial forces.

In the late 1990s, the Peruvian government granted concessions to allow the construction of a cable car and a luxury hotel, including a tourist complex with boutiques and restaurants and a bridge to the site. Many people protested the plans, including Peruvians and foreign scientists, saying that more visitors would pose a physical burden on the ruins.

In 2018, plans were restarted to again construct a cable car to encourage Peruvians to visit Machu Picchu and boost domestic tourism. A no-fly zone exists above the area. UNESCO is considering putting Machu Picchu on its List of World Heritage in Danger.

During the 1980s, a large rock from Machu Picchu's central plaza was moved to a different location to create a helicopter landing zone. In the 1990s, the government prohibited helicopter landings.

In 2006, a Cusco-based company, Helicusco, sought approval for tourist flights over Machu Picchu. The resulting license was soon rescinded.

Tourist deaths have been linked to altitude sickness, floods and hiking accidents. UNESCO received criticism for allowing tourists at the location given high risks of landslides, earthquakes and injury due to decaying structures.

In 2014, nude tourism was a trend at Machu Picchu and Peru's Ministry of Culture denounced the activity. Cusco's Regional Director of Culture increased surveillance to end the practice.

From 1994 to 2019, the Chief of the National Archaeological Park of Machu Picchu was Fernando Astete, a Peruvian anthropologist and archaeologist, who worked for more than 30 years on the preservation, conservation and research of the site.

As a result of his research as director of the Park, the construction processes and functions of the sanctuary were acknowledged by the scientific community and a better understanding of the Inca landscape was given to the general public, who increasingly started to implement more sustainable tourism in the area, as a sign of respect for the site.

During the 2022-2023 Peruvian protests against Dina Boluarte and the Congress of Peru, protesters blocked various routes to Machu Picchu, trapping thousands of tourists at the mountain citadel in December 2022, resulting with the government having to airlift stranded visitors. Due to the complications surrounding visitors and the protests, the Ministry of Culture closed Machu Picchu from the public indefinitely on January 22, 2023. It reopened the next month, on February 15, 2023.

Who lived at Machu Picchu? Servants hailed from distant lands conquered by the Incas, genetic study finds   Live Science - July 27, 2023

A new DNA analysis of human remains buried at Machu Picchu yields information about servants to the Incas. Men and women who served Incan royalty at Machu Picchu weren't locals; they came from distant lands conquered by the empire, a new study finds. An international team of researchers analyzed the ancient DNA of more than 30 people buried at Machu Picchu who were likely servants attending the Incan elite, and compared the genetic data with the DNA from other ancient human remains and modern people from the region. The results revealed that the servants hailed from throughout the Andean highlands, as well as from all along the coast of Peru

Machu Picchu: Ancient DNA Sheds New Light on Lost City of The Incas   Science Alert - July 27, 2023

Standing atop the mountains in the southern highlands of Peru is the 15th-century marvel of the Inca empire, Machu Picchu. Today, the citadel is a global tourist attraction and an icon of precolonial Latin American history - but it was once the royal palace of an emperor. An international team of researchers has uncovered the incredible genetic diversity hidden within the ancient remains of those who once called Machu Picchu home

Ancient and hidden, Machu Picchu's complexity uncovered by archaeologists   NBC - January 21, 2022

Hidden deep in the Peruvian jungle and shrouded beneath thick foliage, archaeologists have discovered a series of long-forgotten structures among the sprawling ruins of Machu Picchu. Cutting through the foliage isn't easy, but such discoveries are becoming more common thanks to a combination of two technologies: lasers that can "see through" obstructions and drones that help archaeologists explore places humans sometimes can't easily reach. Around a dozen small structures were identified less than 5 miles from the main remnants of the 15th century Inca city, on the outskirts of a ceremonial site called Chachabamba. The scientists used a type of remote-sensing technology known as light detection and ranging, or lidar, which bounces laser pulses off surfaces to detect features and map their contours. The laser scans also revealed stone channels running partly underground that supplied water throughout the Chachabamba site. The researchers then developed models based on the slope and depth of the canals to re-create how water may have flowed to the various ritual baths.

The Inca citadel of Machu Picchu in Peru was occupied from around 1420-1530 AD, several decades earlier than previously thought   CNN - August 3, 2021

The emperor Pachacuti, who built Machu Picchu, rose to power earlier than expected. This means Pachacuti's early conquests took place earlier, helping to explain how the Inca Empire became the largest and most powerful in pre-Columbian America. Based on historical documents, it was thought that Machu Picchu was built after 1440, or maybe even 1450. However, Burger and his team used accelerator mass spectrometry (AMS) dating of human remains to get a more accurate picture.

Machu Picchu was hit by strong earthquakes during construction   Science Magazine - October 27, 2019

The Incan citadel of Machu Picchu in Peru is known for its marvelous stonework. But several structures at the site suffered through at least two earthquakes as they were being built, a new study suggests. Those temblors not only damaged walls, but also triggered a sudden change in construction techniques. The study an archaeological survey of three of Machu Picchu's most significant temples - reveals more than 140 examples of damage. These include large blocks of stone that have shifted or whose corners have been chipped. Some of this damage can be attributed to slumping rocks or soil beneath the temples. But the movement of many damaged blocks, including substantial gaps between some formerly interlocking blocks of stone, was likely driven by seismic shaking from at least two major quakes, the team concludes. ThatŐs because the type of damage seen on the corners of blocks embedded in the stone walls only occurs as they rhythmically clatter against each other during an earthquake

Controversial gas from Peruvian Amazon arrives in UK   BBC - March 4, 2017

A tanker docking in the UK is transporting a controversial cargo of gas from the Peruvian Amazon. It is thought to be the first shipment to the UK from the Camisea project in rainforest 60 miles from Machu Picchu Supporters of fracking say the UK should frack its own gas, rather than importing from sensitive regions like the Amazon. But opponents of fracking say the practice creates disturbance and pollution and fuels climate change. The tanker Gallina, owned by Shell, is scheduled to arrive at the Isle of Grain in Kent. The gas project at Camisea field has been hugely contentious.

Using ancient DNA, researchers unravel the mystery of Machu Picchu   PhysOrg - October 1, 2015

The Inca built the site's 15th-century ruins without mortar, fitting the blocks of stone so tightly together that you still cannot fit a piece of paper between them. The design included steeped, agricultural terraces to boost planting space and protect against flooding. But despite its distinction as one of the most iconic and important archeological sites in the world, the origins of Machu Picchu remain a mystery. The Inca left no record of why they built the site or how they used it before it was abandoned in the early 16th century. One thing that makes Machu Picchu so interesting is the idea that actually the population buried there doesn't reflect just a local population.
