The Lost City of Chan Chan | Lost Cities with Albert Lin

[music playing]

ALBERT LIN: I'm headed to the lost city

of Chan Chan, once the beating heart

of the mighty Chimu empire.

Is that a pyramid?

I think that's a pyramid.

A pyramid at Chan Chan.

Can I find the answers inside the city walls

as to why the children had to die?

Built over a thousand years ago, amazingly much of the city

has survived.

And I've been told to expect something spectacular.

Look at these walls.

They stretch as far as the eye can see.

I got my drone up, taking a closer look right now.

Looks like a labyrinth of walls.

I'm using photogrammetry data with graphic modeling

to rebuild the city and these extraordinary walls.

Here they are restored to their full glory, a truly awe

inspiring sight rising out of the desert

like something out of a fable.

At its dazzling peak in the 15th century,

the city was a bustling home to 60,000 people,

about the size of London at the time,

and covering 14 square miles.

This is one of the greatest cities of human history.

So why did it collapse so suddenly?

I'm here to meet Peruvian archaeologist,

Arturo Paredes Nunez, who's been working here for years.

Ironically his last name means wall.

[speaking spanish]

This is Chan Chan.

Look at all these carvings here.

It's-- it looks like digital fish.

The Chimu covered the city with carvings of the ocean.

Wow.

Look at these.

They're everywhere.

But among all these artworks is one Arturo

really thinks I need to see.

An entire wall in the central palace

is devoted to a giant mural over 170 feet long.

Wow.

Look at this.

What is this?

ARTURO PAREDES NUNEZ: [speaking spanish]

ALBERT LIN: Fish.

Yes.

[speaking spanish]

And each one of these is actually a wave moving

down towards the coastline.

Are these currents?

[speaking spanish]

ALBERT LIN: All these fish, they're going in a direction.

They're traveling from south to north.

They're actually following the course of a current,

the Peruvian current.

But a closer look reveals that the mural also depicts a moment

of great change, another current coming back

in the other direction, fish swimming in the opposite way,

north to south.

Incredible.

Is this right?

Did I get this?

Did I get this right?

It looks like the Chimu are recording a dramatic shift

in the ocean currents.

And when that happens, something else dramatic happens, too.

A violent shift in the climate.

Were the Chimu recording a huge natural disaster

on those walls?

Were they chiseling a premonition

of their own destruction?

I need to check the data to see if they were right.

This is a dry, arid desert.

But a sudden switch in the Pacific Ocean current

can trigger violent change and devastating rain.

Look at this.

Everything flips.

Because the ocean currents are tied to the weather currents.

Everything's tied together.

I know this kind of thing.

I live on the Pacific coast myself, just in North America.

This climate shift is called an El Nino.

These days, it happens about once every five years.

But once in a generation, you get a really

big or long lasting event.

That's called a Super El Nino.

And the impact can be catastrophic.

Wait a minute.

Look at this, the data right here, this rainfall data.

Every year for the last decade, less than half an inch of rain.

And then boom, 2017, one big spike,

four inches of rain in a single year

completely out of the blue.

It happened as recently as 2017, destructive floods in Peru

caused by torrential rains triggered by a severe El Nino.

Maybe there's clues in the experiences in that El Nino

that'll tell me what might have happened to the Chimu.

I'm gonna go try to meet some people.

In 2017, the city of Trujillo, just three miles from Chan Chan

and also sandwiched between the sea and the mountains,

was one of the worst hit.

[dog barking]

I'm here to meet some people who almost lost everything.

One local family filmed the flood

as it tore through their home.

Never seen anything like this before,

this much moving material, water just rushing

down through the streets.

This whole thing would have been a river.

You can actually see the storm in the background.

[inaudible]

The more I talked to people in Trujillo,

the more I hear this word, [inaudible]..

It doesn't sound like Spanish to me.

[inaudible] is Quechua or is--

Quechua.

It is?

Quechua is an ancient language of Peru, predating the Spanish.

Wow, that's incredible.

This has happened so many times for so long

that there's an ancient word.

It's something that's embedded in the memory.

[inaudible]

[speaking spanish]

An avalanche.

This term, [inaudible],, is used to describe a combination

of water, mud, stone, debris.

Coming not from the ocean in the west,

but from the east in the mountains behind the city.

Is it possible that the same type

of event happened to the Chimu?

If it did, then there must be some way

of finding evidence that an El Nino

event happened in their time.

And the answers may be up in those mountains.

A pyramid at Chan Chan.

Can I find the answers inside the city walls Kann ich die Antworten innerhalb der Stadtmauern finden? Posso trovare le risposte all'interno delle mura della città Posso encontrar as respostas dentro das muralhas da cidade?

as to why the children had to die? perché i bambini dovevano morire? porque é que as crianças tinham de morrer?

Built over a thousand years ago, amazingly much of the city Vor über tausend Jahren gebaut, erstaunlich viel von der Stadt Construída há mais de mil anos, surpreendentemente grande parte da cidade Bin yılı aşkın bir süre önce inşa edilen şehrin şaşırtıcı bir şekilde büyük bir kısmı

And I've been told to expect something spectacular. Und mir wurde gesagt, ich soll etwas Spektakuläres erwarten. E mi è stato detto di aspettarmi qualcosa di spettacolare. E disseram-me para esperar algo espetacular. Ve bana muhteşem bir şey beklemem söylendi.

Look at these walls. Olha para estas paredes.

They stretch as far as the eye can see. Si estendono a perdita d'occhio. Estendem-se até onde a vista alcança. Göz alabildiğine uzanıyorlar.

I got my drone up, taking a closer look right now. Tenho o meu drone no ar e estou a dar uma vista de olhos mais de perto. Drone'umu kaldırdım, şimdi daha yakından bakıyorum.

ARTURO PAREDES NUNEZ: [speaking spanish]

ALBERT LIN: Fish.

Yes.

down towards the coastline. em direção à costa. kıyı şeridine doğru.

Are these currents? São correntes? Bunlar akıntı mı?

ALBERT LIN: All these fish, they're going in a direction.

They're traveling from south to north.

They're actually following the course of a current, Aslında bir akıntıyı takip ediyorlar,

the Peruvian current. der peruanische Strom.

But a closer look reveals that the mural also depicts a moment Mas um olhar mais atento revela que o mural também retrata um momento Ancak daha yakından bakıldığında duvar resminin aynı zamanda bir anı da tasvir ettiği görülür

of great change, another current coming back de grande mudança, outra corrente a regressar büyük değişimin, başka bir akımın geri gelmesi

in the other direction, fish swimming in the opposite way,

north to south.

Incredible.

Is this right? É correto?

Did I get this? Será que percebi isto?

Did I get this right? Será que percebi bem?

It looks like the Chimu are recording a dramatic shift Parece que os Chimu estão a registar uma mudança dramática Görünüşe göre Chimu dramatik bir değişim kaydediyor.

I need to check the data to see if they were right. Haklı olup olmadıklarını görmek için verileri kontrol etmem gerekiyor.

This is a dry, arid desert. Este é um deserto seco e árido. Burası kuru, kurak bir çöl.

can trigger violent change and devastating rain. pode desencadear mudanças violentas e chuvas devastadoras. şiddetli değişimi ve yıkıcı yağmurları tetikleyebilir.

Look at this.

Everything flips. Tudo vira. Her şey tersine döner.

Because the ocean currents are tied to the weather currents. Porque as correntes oceânicas estão ligadas às correntes meteorológicas. Çünkü okyanus akıntıları hava akıntılarına bağlıdır.

Everything's tied together. Tudo está ligado.

I know this kind of thing. Ich kenne so etwas. Eu conheço este tipo de coisas.

I live on the Pacific coast myself, just in North America. Eu próprio vivo na costa do Pacífico, mas na América do Norte. Ben de Pasifik kıyısında yaşıyorum, sadece Kuzey Amerika'da.

Maybe there's clues in the experiences in that El Nino Talvez haja pistas nas experiências desse El Nino Belki de El Nino'daki deneyimlerde ipuçları vardır.

that'll tell me what might have happened to the Chimu. que me dirá o que pode ter acontecido aos Chimu. Chimu'ya ne olmuş olabileceğini bana söyleyecek.
