Machu Picchu: The Citadel

Posted on September 1, 2020 by Lark

Now that we’ve talked about Inka Pachakuteq and the history of Machu Picchu and have explored the outskirts of the site, it’s finally time to explore the citadel! That’s what they call the main area of buildings onsite even though “citadel” gives more of a fortress vibe, and we’ve already covered the fact that historians think Machu Picchu was most likely a royal estate. That, at least, is the assumption that we’re going to go with as we walk through the site and learn about what the different buildings were potentially used for. Again, everything I say may or may not be true. Thanks to the Incas’ lack of a written language, best guesses are sometimes all that historians can make. So, here are a bunch of best guesses about the ruins at Machu Picchu! Just insert a “maybe” before each statement I make from here on out.

Everyone looking tired but happy after finishing our morning hikes!

The site can be divided into two main sectors, farming and urban. The farming sector consists of the terraces, many of which are still unexcavated. Vegetation grows quickly in the cloud forest! There are also some buildings around the terraces that may have been used to house farmers, but the majority of the buildings are located in the urban sector/citadel.

After you enter through the ticketing area, you walk up lots of stairs and past lots of farming terraces until you finally get your first glimpse of the urban sector. There are a bunch of different viewpoints from which you can get a low-flying bird’s eye view, and at one of these is the “watchman’s post” or maybe “the hut of the caretaker of the funerary rock” or “call it whatever you want because who knows”. This three-walled structure has a great view of the citadel and the surrounding valley and is one of the few buildings with a restored thatch roof. Remember that this type of roof would have been standard, so based on that alone, the urban sector would have looked very different. Just outside, there’s a large “funerary rock”, carved into an altar and used for embalming and mummification… or maybe used for animal sacrifices. In the nearby field, a number of skeletons were excavated which is part of the reason for the mummy theory. In that case, the hut would have potentially been used in the mummification process as well.

The “upper cemetery” where they found a bunch of graves. You can see the funerary rock at the far end of the field, plus the “whatever it is” hut just behind the rock. (Side note, some of the pictures in this post, including this one, are from my first trip to Machu Picchu. There were a few things that I wanted to show that I didn’t have pictures of from this visit, so if you notice that the weather randomly appears to have changed between pictures, that might be why.)

I’m going to give you a little preview of our route. We started at the hut that’s out of frame to the upper right. We’ll enter town through the main gate, which is where that big group of people is gathered. From there, we’ll walk through that first group of buildings and then stay to the left to visit the plaza (the dirt patch), go up the Sacred Hill behind it (with all of those narrow terraces). Next, we’ll cross the main grassy plaza to the very back of the site where we’ll see a Sacred Rock, and then we’ll head back towards the starting point through the buildings on the far side of the main plaza. (If that made no sense, sorry! I tried. Ignore me and just continue reading.)

A dry moat separates the outer buildings and farming areas from the urban sector. Through the main gate (that used to have a door with a locking mechanism!), you enter into the upper part of town which contains support buildings like storehouses and public buildings and the remnants of a quarry that likely supplied much of the stone for the buildings. What an exciting welcome to town, right? But it makes sense not to put the really important stuff right next to the city gate, just in case (Lara speculation).

The dry moat runs along that staircase in the front, and the main gate is just out of frame to the left.

The rock quarry as viewed from the Sacred Plaza

Downhill from these structures is where things start getting interesting. Not surprisingly, the most unique building in the city is the Sun Temple. It has a curved wall with that classic imperial stonework, and it’s built above a giant boulder. The top of that boulder was carved into an altar that was used for animal sacrifices (to read the future in their entrails… ick). This was also where the Inka would come to drink chicha (corn beer) with his “father” the sun, as the Incas believed that the Inka (king) was descended from the sun god, Inti (side note: to keep the royal bloodline pure, each heir had to be a son of the Inka and his sister).

The Sun Temple. There are windows facing to the north and to the east. The east window is aligned to the sun position on the winter solstice.

See the carved rock that makes up the floor? That was used as an altar.

The Incas mummified their dead and treated them a bit like they were still living, so underneath the temple is a “royal tomb”, basically a cave where it is believed that the Inka’s mummy was kept. Even after Inka Pachakuteq died, it is likely that his mummy was brought back to Machu Picchu, kept beneath his father’s temple, and given food and drink (not quite sure about the logistics of that).

Near the sun temple are the royal apartments, aka the residence of the living, pre-mummified Inka. The spring on Machu Picchu Mountain was first directed through the Inka’s apartment so that he could have the freshest possible water, and from there, it flowed through a series of ceremonial fountains. The residence consists of a central patio area surrounded by two large and two small rooms.

Beyond the rock quarry and royal apartments is the main sacred area for the town. A small plaza is bordered by two temples and another room that could have been the priest’s dwelling. You can tell that the temples are important buildings just by looking at their quality stonework.

One of the fountains that used to flow with water from the spring. The water would still flow through here, but it’s been redirected for tourism purposes (bummer).

View from the quarry. Straight ahead, you can see the Sacred Plaza with its two temples, and behind that is the terraced Sacred Hill. Another temple, the Moon Temple, is located on the back of Huayna Picchu, the tall mountain peak that you see straight ahead.

The main temple has only three walls. They’re not sure exactly who this temple was dedicated to, especially since the Sun Temple is elsewhere, but clearly it was someone important! You can see that the collapse in the corner isn’t because the rocks shifted. The bottom rock is actually sinking into the ground, so it’s likely some sort of foundational problem. That could have been caused by an earthquake, or it could have been a water-related failure.

This is the Temple of Three Windows. Can you guess how it got its name? It likely was covered by a gabled thatch roof with the side nearest to us left open.

The sacred spaces continue up “Sacred Hill”. There are more temple-like buildings with high-quality stonework, but again, the exact use of each space isn’t really known. At the top of Sacred Hill is one of the only remaining “Intiwatana”, or “sun fastener”, stones. This carved rock was used during the winter solstice celebration, Inti Raymi, to symbolically tie the sun to the earth. Inti Raymi was a festival to ask Inti not to abandon his people, to move closer instead of farther away. Otherwise, the stone was also used to measure the solar year and keep track of important sun dates like equinoxes and solstices. It was not, however, a sundial or solar clock. The Incas didn’t have clocks as they didn’t measure days in hours and minutes. This hill was also the priest’s pulpit. He could stand high above the main plaza and address the people gathered below.

Walking up Sacred Hill. You can see the Sacred Plaza in the bottom left, with the main temple closest to us and the maybe-priest’s-house across the plaza from there. And then there’s the rock quarry, and the hut where we started is perched up on the terraces near the top of the picture.

Intiwatana. Originally, it was probably polished… the rain is giving it a decent shine in this picture. I’m imagining a granite countertop-level shine.

The entrance to the site is on the far end straight ahead, and Sacred Hill is the one to the right with all of the terraces. The terraces on Sacred Hill are very shallow. This shows that they were mostly for protecting against erosion and were also used as decorative gardens, not for actual farming.

Looking up the side of Sacred Hill. You can see those shallow terraces at the right edge of the picture. From this angle, it’s pretty clear why they decided this needed some erosion-prevention terraces!

I like this picture because I think it really shows how important the terraces are to making this site a viable location for building. Without those terraces, there’s no way that the site could have handled the weight of the buildings, and erosion definitely would have caused some serious collapses. I also like looking at the main plaza and seeing the effort that went into creating such a large, flat space.

Sacred Hill is up to the left. The main plaza, in the middle, was used for festivities and ceremonies.

Across the lawn, right in front of Huayna Picchu, is a “Sacred Rock”. It’s clearly important because a stone pedestal was built around it (it’s a natural projection of the mountain), but what were people worshipping there? It supposedly could look like a puma or a guinea pig, but personally, I don’t see it. Another possibility is that it was simply a representation of a sacred mountain peak. Mountains were believed to have spirits that were considered protectors of the people. I’m going to go with that because I can definitely see “mountain” in this rock.

You tell me… puma? guinea pig? or mountain? This rock was probably polished as well.

It seems like a pretty cushy existence to be a Machu Picchu alpaca. They just wander around, eat, and get fawned over by tourists.

Finally, moving back towards the main gate but on the other side of the main plaza, there are TONS of buildings. These were apartments for support staff, storehouses, and other utility spaces. There are various interesting features sprinkled throughout these rooms, including these two “water mirrors”. Some guess that they were used to reflect the night sky and study the stars, but that seems silly because why look down at a reflection when you could look up at the real thing? Oh well, at this point, what’s one more unsolved mystery?

Water Mirrors. Does it not seem a bit silly to use these for astronomical purposes? To use these liiittle water pools rather than the big night sky?

I’m obsessed with the way that they integrated these ginormous boulders.

I don’t know why things like this still surprise me, considering I know how skilled the Inca stonemasons were. But it’s so seamless!

On the way out, you walk through one of my favorite parts of town. I don’t know what it was used for… maybe just more support buildings? But the reason I love it is because there are large boulders all over the place, and the buildings are built right into/onto/around them. It’s so cool! There’s one in particular that’s very important, the Temple of the Condor. There’s a huge rock at the center that somehow looks like a landing condor? Condors, pumas, and snakes were sacred animals for the Incas, so it was likely an important religious space.

This is the world’s least helpful photo of the Temple of the Condor, but clearly I was more focused on the ridiculousness of the wall on top of that slant than on the entirety of the condor-shaped rock. I’m pretty sure that the head is the part on the left side of the picture, and that crazy slanted rock is maybe one of the wings?
This is what happens when you do most of your learning about a site AFTER you visit. To be fair, though, it’s very hard to understand what anything is talking about until you’ve been there. I guess that’s one argument for taking a tour, but even so, I think I still prefer exploring on my own.

In the bottom middle, you can see the big rock in the Temple of the Condor. You can also see the hut from the very beginning of our tour in the top middle!

By the time we were about halfway through the citadel, we were all more than ready to call it a day. Mom and Dad actually said before we even entered the town that they felt like they’d already seen enough. I insisted that we walk through, but I understood their exhaustion. We had already done a lot of walking! We walked through the exit gates EIGHT hours after we walked in. Eight. Hours. But we did it! We survived! And we did/saw everything we wanted to do/see which is VERY impressive.

Farming terraces along the edge of the citadel. The buildings you see in the distance could have been housing for farmers.

Survived! Mom’s somehow still smiling after 8 hours of walking.

We took the bus back to town and then mostly hung out in our hotel until it was time to head to the train station for our ride back to Cusco. We were taking a train that went all the way back to the city, rather than the other option of having to transfer to a car in Ollantaytambo. Good in theory, but I probably should have looked more closely at the schedule. It’s insane. The train from Machu Picchu to Ollantaytambo takes about 1:45. To drive to Cusco from there would take about 2 hours. The train, on the other hand, took nearly 3 HOURS. How? Well, please direct your attention to the helpful map below. I traced the train tracks in blue.

When we felt like it was time for the ride to be over, we called over the train attendant and grilled him for answers. We could literally SEE Cusco, and he said it was still going to take at least a half-hour to arrive at the station. I was so exhausted that I almost cried. He explained that in order to get down into the valley, the train goes down a series of switchbacks. Switchbacks! For a train! It hits a dead end, they switch the tracks, the back of the train becomes the front, and it continues on until the next dead end. I ranted in delirious Spanish about how silly that was, and he excused himself/escaped at the first opportunity.

Eventually, though, we made it. Everyone was tired of sitting, so we walked the 15 minutes to our hotel and collapsed. Talk about a long day.

Manco Cápac Plaza in Aguas Calientes. Manco Cápac is the legendary first Inka, and it’s uncertain whether he actually lived or if he’s simply a legend. He’s one of the main characters in the legend that explains the beginnings of the Inca civilization.

The ride home also included some entertainment, including a fashion show of alpaca clothing products (surprisingly entertaining) and some interesting dances with this Andean folk character.

Inka Pachakuteq and the History of Machu Picchu

Posted on August 25, 2020 by Lark

Before I talk about our visit to Machu Picchu, I think it’s important to understand some of the backstory to fully appreciate its awesomeness. Visually, it’s incredible no matter how little you know, but the story is a good one! Remember, though, that the Incas had no written language, so the earliest written accounts of their history come from oral histories recorded by the Spanish. That information is far from comprehensive, so in combination with archaeological evidence, a certain amount has been extrapolated (by experts, not by me). In some cases, there are disagreements about the specifics, so just read along with a big “MAYBE” disclaimer in the back of your mind. Okay! As I was saying…

Our story begins in the 15^th century with an attack on Cusco by the Chanca people, a group with military strength comparable to the Incas. The Inka (king) at the time, Viracocha, abandoned his people. He fled the city in fear and took his heir with him. Some king! Another son, Cusi Yupanqui, decided to stay and defend the city, leading the Inca army with one of his brothers and a few other Inca chiefs. They won decisively, crushing the Chanca army and humiliating Viracocha. Having gained the support of the people during the battle, Cusi Yupanqui later declared himself the new Inka, forced his father to abdicate, and changed his name to Pachakuteq which means “earth-shaker” or “he who turns the world upside down”.

If that seems like a bold name statement, well, it is. But Pachakuteq knew that he was destined for greatness. First, as the battle against the Chanca proved, he had an aptitude for military strategy and leadership. Second, as a child, he had a vision where the sun god, Inti, called him “son” and told him that he would conquer many nations, and when he did, to honor and remember him. Pachakuteq took this to heart, elevating Inti throughout the empire as the supreme Inca god and constructing grand tributes in his honor, including Qorikancha in Cusco and other opulent temples in important cities.

Pachakuteq quickly defined himself as an Inka of great ambition. During his ~30 years as Inka, he reorganized the government structure and set out to expand the small Inca kingdom into an empire. He led with diplomacy, giving neighboring tribes the opportunity to surrender peacefully to avoid bloodshed. Those who refused were quickly overpowered by the Incas’ powerful military. To integrate the new tribes, their leaders were killed, and royal children were sent to Cusco to be indoctrinated. Sons later returned to their native lands to rule under the Inka, and daughters were married off to other leaders within the empire to build unity. Pachakuteq started an age of expansion that continued until the Spanish invasion.

In addition to growing the empire through his conquests, Pachakuteq undertook grand construction projects that showcased the Incas’ superior engineering and craftsmanship abilities. He was very involved in the design decisions and was likely shown clay models of proposed projects, approving each of them himself. The famous “imperial style” stonework, where stones are perfectly cut and fit together without mortar, was his preferred style as it highlighted the skill of the craftsmen and demonstrated the power and dominance of the empire. Besides completely overhauling Cusco, he also built several royal estates, assumed to be monuments to his victories.

Some quality “imperial style” stonework. I love it.

We’ve already visited one of these estates, Ollantaytambo. Another is at Pisac, and finally, the most impressive, Machu Picchu. The estates celebrated Pachakuteq’s successes and were luxurious retreats for him and his family. Machu Picchu was the last one built and is thought to commemorate his conquest of the Vilcabamba Valley.

So, how did this city in the clouds come into being? The first step was to choose a site, and while the reasons for the specific site selection aren’t known for certain, there are some clear advantages to this one. A major benefit is its access to clean water via a spring located on the mountain of Machu Picchu. It also has views of the Incas’ most sacred mountain peaks, and its challenging location offered the opportunity to show off what the Inca builders were capable of.

I totally support the Incas’ location choice.

You can see the Urubamba River in the bottom left corner… it actually wraps around Huayna Picchu (that peak in the middle), so it’s nearly surrounding the site.

Here’s the Urubamba River again! See how it wraps right around Huayna Picchu?
Also, can you spot the city? If you saw this landscape before it was built, would you have thought, “Now THAT’S the perfect place for a city!”?

While the site looks conveniently flat today, that’s not how it started out. The “city” is located between two mountain peaks, or “picchus” – Machu Picchu (old peak) and Huayna Picchu (young peak) (Huayna Picchu is the one that you see in the background of the classic Machu Picchu photos). Before it was even possible to build the structures, the dip between the two peaks had to be filled in and leveled off to create a flat area for building. To stabilize the ground and decrease the risk of collapse from the weight of the new city, terraces were constructed, deep foundation and retaining walls installed, and drainage systems designed. Estimates are that 60% of the construction at Machu Picchu is actually underground.

Leave it to the Incas to create flat ground on top of a mountain. Well, I guess it’s not on TOP… so leave it to the Incas to create flat ground between two mountain peaks. Yeah, that’s no less insane.

The tallest peak in the background is Machu Picchu.

The 700+ terraces at Machu Picchu create about 12-14 acres of farmable land. This likely wasn’t sufficient to support the estimated 750-1000 people who were on site when the Inka was there, and additional food was brought in to supplement the harvest. Even so, for farming on a mountaintop, it sounds pretty good to me! When the Inka wasn’t in town, a skeleton staff was left to maintain it. The remains of over 170 people were found at the site, and bone analyses indicate that people came from all over the empire to serve there.

Llamas and alpacas aren’t native to the area but were brought by the Incas

Back to the terraces… I’ve previously talked about the integrated irrigation systems that the Incas included in some of their terraces. At Machu Picchu, it was determined that irrigation was unnecessary due to the wet and humid climate. Instead, extra attention had to be paid to water management. Analysis of the terraces revealed that they were constructed in layers to facilitate drainage with large stones at the bottom, a mix of packed sand and gravel in the middle, and topsoil on the surface, probably carried up from the more fertile valley to better support crops.

Morning mist rising up from the Urubamba River. Even when it doesn’t rain, the mornings are still nice and damp!

This is a good angle to appreciate the stabilizing terracing that was included to help level off and protect the city from collapse/erosion.

I’ll never get tired of this stonework. Please, admire.

Huayna Picchu. You can see some terraces on the top… these were likely for erosion protection rather than for farming. Can you imagine having to hike up there to take care of your potatoes? Yeah, right!

With the foundations completed, work could finally begin on the buildings. I’ll talk more about the specifics next time, but assuming the site was, in fact, a royal estate, it included royal residences, housing for nobles, ceremonial and religious spaces, and support spaces like servant housing and storage. There are about 200 buildings in total.

The city. Now imagine those buildings covered with thatch roofs!

Did you know that Machu Picchu is actually built at the intersection of two fault lines? That means lots of earthquakes, but the good news is that the Incas knew what they were doing. Here are a few construction techniques that helped their structures to survive for so long:
See how the walls are slightly inclined inward? You can see it best if you look at the corner. This slight incline at the inside corners, plus the use of L-shaped stones on the outside corners, helped to stabilize the walls.

We’ve already talked about this, but the mortar-less construction was great for earthquakes, too. Stones can wiggle around during the earthquake, and after it’s over, they settle right back into their perfectly-cut places.

See how the doorways and windows are actually trapezoidal, rather than rectangular? This helps to make stronger, more stable openings!

Beyond the construction work on the mountain, there was also a massive road-building project to link this new estate with other significant parts of the Empire. The road from Cusco winds 27 miles through the mountains, passing Ollantaytambo and continuing its way up, down, and around the peaks until reaching Machu Picchu. A much easier option would have been to construct a road along the Urubamba River, but that’s no fun! It’s possible that Machu Picchu was also a pilgrimage site for the worship of Inti, and the long, difficult journey to get there was meant to test and prepare the pilgrims.

One of the reasons Machu Picchu is so archaeologically significant is because the Spanish never visited. That means that religious structures were never defaced in their campaign to Christianize the pagan civilizations, giving valuable insight to researchers. Why did the Spanish never make it there? The site was completed in the 1450s or 60s and was abandoned less than 100 years later. What happened? No one is really sure. Perhaps the site was deserted after Pachakuteq’s death. Perhaps there was an epidemic or an attack by the jungle tribes that wiped it out. Perhaps it was simply forgotten. Likely, most people in the empire had no idea it even existed.

Part of the original Inca road. How. Cool.

The buildings transition seamlessly into the mountain!

Machu Picchu sat abandoned for hundreds of years and was only brought to the world’s attention when it was “rediscovered” in 1911 by an American historian, Hiram Bingham, as he was searching for the “lost city” of the Incas, Vilcabamba (where Manco Inka set up his remnant Neo-Inca state). Bingham gets the credit for finding it, but in reality, it was no secret. He traveled along the Urubamba River, asking if anyone knew of ruins in the area, and was shown to Machu Picchu by a farmer. There were multiple local families living there and farming on the old terraces. Also, as the site was excavated, the absence of precious artifacts suggested that treasure hunters had already plundered it.

Hiram Bingham and crew walked up the mountain. It’s an exhausting uphill trek! But nowadays, you can take a bus up these crazy switchbacks. Not recommended for sensitive stomachs, but definitely preferred to walking!

I can’t imagine walking around this place for the first time as an explorer!

Bingham and his crew excavated the site for five years and sent artifacts back to Yale, where he worked, for further research. Peru is still trying to get these items returned today. In 1981, Peru created a national sanctuary protecting Machu Picchu and its surroundings. In 1983, it was declared a UNESCO World Heritage Site as “a masterpiece of art, urbanism, architecture and engineering” and “a unique testimony of the Inca Civilization”.

Next time, we’ll take a closer look at the details of the site!
