7 Historical Facts about Machu Picchu

1.  Machu Picchu was built by Inca "Pachacuti"

Peruvian culture started somewhere around 5000 B.C. In the north of Lima, Caral is one of the oldest civilizations in Peru; they lived in the desert and survived trading with their neighbors while Mesopotamia, Egypt, China, and India were developing.

The Incas appear in the history line around the 1300s. Many Inca cities were built over the foundation of past civilizations, like Cusco, the capital. However, no traces of earlier culture were found in Machu Picchu. This means that the Incas were the first to arrive at these mountains. Machu Picchu was built between 1400 AD and 1500 AD. This period belongs to Pachacuti, the 9th Inca ruler, and his son Túpac Inca Yupanqui.

2.  Machu Picchu was abandoned after the Spanish Invasion

Despite many theories of diseases, wars, and hunger in Machu Picchu, it might have suddenly caused the people to leave the great citadel. Nowadays, we know that Machu Picchu was still inhabited during the first years of the conquest and abandoned during the retrieve into Vilcabamba, the last capital of the Incas.

3.  Machu Picchu was never the "lost" City of the Incas

Hiram Bingham arrived at Machu Picchu on July 24th, 1911. He found 3 families living at the first building right after the entrances: Bingham’s first guide was a little boy 11 years old named “Pablito,” he used to play inside Machu Picchu and knew the Inca city by hand; all this was documented in the first pictures taken in black and white.

4.  Hiram Bingham did not discover Machu Picchu

When Hiram Bingham arrived in 1911, he found a painting in the Temple Of The Three windows saying “Agustin Lizarraga 1902”. He was a farmer from Santa Teresa, a town next to Machu Picchu. Unfortunately, he fell into the Urubamba River in 1912 and died.

Everybody agrees that Hiram Bingham did not discover Machu Picchu. However, Hiram Bingham gave scientific and historical value, bringing attention to this citadel. In 1913, “National Geographic” magazine published a detailed article introducing Machu Picchu and its work, revealing the great citadel. So we can say, in fact, that Hiram Bigham is the scientific discoverer of Machu Picchu.

5.  The Inca Trail was used as a Pilgrimage path to Machu Picchu

Machu Picchu has 2 ancient access routes: One is an easy access path along the Urubamba River banks, allowing the arrival to the great citadel in just one day. The other one is the stunning Inca Trail that climbs mountains and arrives at the different temples before arriving at Machu Picchu.

Many historians suggest that the Inca Trail to Machu Picchu had a ceremonial purpose: a hike to prepare travelers for Machu Picchu, the Sacred Citadel. The Inca Trail might represent the first Inca King, Manco Inca’s journey when they exited the Island of the Sun in Lake Titicaca and traveled across the Mountains to Cusco Valley, where they found the capital of the great empire.

6.  Yale Returned Artifacts To Peru

Hiram Bingham III excavated in Machu Picchu between 1912 and 1915, and the artifact found during this time left Peru under a special governmental decree. The Materials were loaned to Yale University for research and needed to be returned. Some artifacts were returned after World War I, but most were kept in the school.

In 2008, Peru’s government filed a lawsuit against Yale, and in 2012, after a partnership agreement between Yale University and the Univerity of Cusco, all artifacts were returned.

7.  Machu Picchu was not finished

The question that everybody asks is if Machu Picchu was finished. Many Inca sites in Cusco were not completed, like Ollantaytambo, invaded by the Spaniards. Most of the rocks the Incas were transporting to build the city were left on the trail; now, these boulders are called “Tired Stones.” The rocks were transported from faraway quarries.

Machu Picchu, on the other hand, the quarry was right there, and the city was completed. However, like any other modern city, it was still growing, so we see unfinished construction in Machu Picchu.

8 Architectural facts about Machu Picchu

1.  Machu Picchu was made earthquake-resistant

Peru is a seismically unstable country situated in the Pacific Ring of Fire, and earthquakes had flattened the cities long before the Inca nation. Machu Picchu is also built between 2 geological fault lines. However, the Inca engineers knew that and made all their cities earthquake-resistant. The stones are cut so tightly that you can’t fit a needle between these spaces.

2. The best part of Machu Picchu is the underground

Modern engineers estimate that 60 percent of Machu Picchu is an underground construction site; we can only see the remaining 40 percent. This doesn’t mean tunnels. The underground structures are the drainage system and the building’s foundations on such a steep mountaintop.

3.  Machu Picchu’s water system is significantly advanced

Before building the city, Inca engineers had to plan how to bring enough water. Machu Picchu is located in the Could Forest, a warm and humid place; the reason why 60 percent of Machu Picchu is underneath is that the Incas were fighting against the humidity against the rain, and they built a vast drainage system to exit the water from the city and avoid landslides. However, they needed to bring water to the citadel and consumption; this needed to be just enough for all living in Machu Picchu.

They decided to build a 749m long canal with a 3% inclination. There were 16 fountains to distribute the water for each neighborhood; the first one at the top was reserved for the king. This inclination allowed the water to run smoothly through the city, even in the rainy season, without causing any trouble.

4. Machu Picchu has 2 Mountains you can climb

Almost all visitors want to climb Huayna Picchu Mountain, but few people know about the other mountain called Machu Picchu Mountain or Montaña. Huayna Picchu will sell out very fast, but you can still climb Machu Picchu Mountain, which offers even more incredible views. Machu Picchu Mountain is the highest mountain at 3,082 meters (10,111 ft.). It’s important to know that Machu Picchu citadel differs from Machu Picchu Mountain.

5.  Machu Picchu was an Astronomical Observatory

Machu Picchu is considered a holy city; there are temples and sacred places all over the town.

Recent studies have shown that most of Machu Picchu’s buildings are oriented toward the most important mountains. One of the best examples is the Intihuatana Stone; the corners of this structure point to Salkantay Mountain, Pumasillo, Yanantin, and the Sungate.

6.  Machu Picchu is divided into 2 sectors

Machu Picchu was very well planned. The town was divided into 2 main sectors divided by a vast wall.

The agricultural sector is the first part of the terraces that the Incas used for farming maize, beans, and fruits. The terraces have an advanced drainage system.

The urban sector is divided by a tall wall; inside, there are temples, palaces, houses, and plazas. There are around 200 buildings that house around 800 to 1000 people in total.

7.  The Spaniards did not destroy Machu Picchu

The conquistadors destroyed most Inca sites like Sacsayhuaman, Ollantaytambo, and Pisaq. However, Machu Picchu was never found thanks to its hidden location, making it one of the Incas’ best-preserved archaeological treasures.

8.  Machu Picchu has a Secret Temple

This is the Temple of the Moon, located behind Huayna Picchu Mountain. Unfortunately, this place is closed to the public and is only accessible to visitors during the early shift for Huayna Picchu.

Machu Picchu also has a local museum below, near the bridge crossing the Urubamba River. You will see the artifacts found in Machu Picchu and many of the first pictures taken in 1911.

7 Curious Facts about Machu Picchu

1.  Llamas are the only foreigners living in Machu Picchu

Machu Picchu has been a protected area and a World Heritage Site since 1983. No one can live inside the citadel. However, during your visit, you will see several llamas gracing freely; they are not native to the area but were brought to Machu Picchu to enhance the site’s beauty and trim the grass.

2. You can walk up to the ruins

Once in Aguas Calientes, you can take the $24 bus to Machu Picchu or follow Hiram Bingham’s 1911 route for 1.5 hours.

The hike is free and offers extraordinary views of Machu Picchu, the Urubamba River, and the surrounding mountains. However, we don't suggest this hiking trail if you are finishing a trek like the Inca Trail, Salkantay Trek, Lares Trek, or any other trekking tour.

3. Only women lived in Machu Picchu?

Among the findings in Machu Picchu, there were around 160 skeletons, most of which were short. Dr. George Eaton, an osteopath, concluded that most of Machu Picchu’s inhabitants were women. Bingham, on the other hand, believed that the site was the “Temple Of The Virgins Of The Sun. “

However, later research will prove that the number of male and female skeletons was almost equal, and the skeletons were short because that was the average height of the Incas during that time.

4.  Machu Picchu has only 2 seasons

Machu Picchu has only 2 seasons: the wet and dry seasons.

The wet season from November to March

The Dry season from April to October

5.  Machu Picchu means Old Mountain

Although there's no written evidence of the name "Machu Picchu," the Incas used their main and widely spoken language, "Quechua," to refer to any place or town around the Empire. The compound Quechua word; “Machu” means old or great, and Picchu means mountain, which can be interpreted as "Old Mountain."

6. Machu Picchu is not the real name

On July 23rd, 1911, Hiram Bingham’s expedition arrived at the small village of Mandor near Aguas Calientes. Once there, the local farmer Melchor Arteaga told the explorers about the presence of many ruins in the nearby mountains. When they asked for the name of the site, he replied, "Machu Picchu."

Unfortunately, there's no official record of that name. The first mention of Machu Picchu was found in Charles Wiener’s book “Pérou et Bolivie,” from 1880. This French-Austrian explorer wrote: “They told me about other villages, Huaina-Picchu and Matcho-Picchu, and I resolved to make one last excursion to the east before continuing south.”

More recently, historians discovered writings from the first conquistador, which included a list of the Inca kings and the cities they built. One line mentions, "Pachacuti built Picchu," which could be the actual name of Machu Picchu and proof that Pachacuti built this incredible city.

Over the years, many names have been suggested, such as Llaqtapta and Karmenqa, but the true name of Machu Picchu still remains a mystery.

7.  There are 2 ways to arrive at Machu Picchu

You can reach Machu Picchu either by train or by taking a hiking tour. There are many trekking tours available like the Inca TrailSalkantay, and Lares. If you choose the train option, you can leave from Cusco and Ollantaytambo by taking the trains from any of the two main companies: PeruRail and IncaRail.
