The Nordic region is
a collection of countries

located in northern Europe.

It stretches from Finland

and the Scandinavian countries
in the east

to the Faroe Islands, Iceland
and Greenland to the west.

The Nordic nations are built
on lands of fire and ice.

Today, engineers in this region
are united in a battle

to build
in extreme environments

and work with nature
to forge the future.

From bridges spanning
frozen fjords in Norway

to geothermal power plants on
Iceland’s dramatic lava fields.

For centuries, Nordic engineers
have tamed

some of the world's
most extreme environments

with extreme engineering.

From deep fjords to
snow-covered mountains,

engineers have conquered these
lands with pioneering projects.

The Svalbard Global Seed Vault
is built

130 meters into
a frozen mountain

in the outer reaches
of the Arctic Circle.

It’s designed to safeguard
the world’s food plants.

Engineers battled the elements
to build this wind farm

on a desolate mountain range

inside the Arctic Circle
in Norway.

On Iceland's
Reykjanes Peninsula,

a pioneering engineering
project is underway

to combat an extreme threat.

♪ ♪

Iceland's volcanic landscape
is dotted

with critical infrastructure,

including the world famous
Blue Lagoon tourist resort

and its neighboring
geothermal power station.

The power station generates
electricity and hot water

for 30,000 people, and
the lagoon is one of Iceland's

top tourist destinations.

Engineers in monster machines
are working around the clock

here to build
a unique superstructure.

Colossal barriers,
the height of office blocks.

The barriers perform
a crucial role

protecting these
vital economic cogs

from the imminent threat
of volcanic eruptions.

Six volcanic systems lie
across the peninsula.

They became active in 2021,

having lain dormant
for the last 800 years.

Engineers immediately
began a colossal

barrier-building project to
divert searing hot lava flows

away from key locations.

♪ ♪

Horn Hrafnsdóttir is
the driving force

behind the barrier project.

[Horn Hrafnsdóttir] What we are
trying to protect

is the Blue Lagoon and
the geothermal power plants

that we can see over there.

[Narrator]
Horn uses state-of-the-art
computer simulations

to predict the path
of future lava flows,

so she knows where
to build the barriers.

Now, the team is racing
to raise the height

of this barrier and plug gaps
along the route

before the next
eruption strikes.

To do this, the team's
first job is to collect

the raw material they need.

The landscape here is filled
with solidified lava

from thousands of years
of eruptions.

It’s perfect for building
durable barriers.

So the engineers use explosives
to break it up.

Giant bulldozers then scoop
and fill huge dumper trucks

with the lava and soil mix and
transport it to the worksite.

Here, an enormous excavator
piles the tough, rocky mix

on top of the key barrier,
protecting the Blue Lagoon.

The hot lava from
the recent eruption

still steams on the other side
of the slope.

Horn uses an aerial camera
to track the team’s progress.

[speaking Icelandic]

The drone gives Horn
a bird's-eye view

of the entire worksite.

The lava field from the last
eruption is easy to spot,

because it’s still too hot
for snow to settle on it.

[Horn] So this was the critical
point, so we are closing that.

We need the slopes to be good.

So when we have earthquakes,
nothing breaks away.

The barriers should work,
but it’s always the question,

does Mother Nature intend
to change something

and do something else?

[Narrator] Work filling
the last gap in the barrier

is now almost complete.

[Horn] I'm very happy
with the work

that’s been done here today.

So we are trying to do our best,

is in good shape.

Now it's a waiting game
until the next eruption

to see if their work is enough

to save these vital cogs
in Iceland’s economy.

♪ ♪

Today, the only way to travel

This new 121 million-euro

♪ ♪

Building this structure is
a Herculean challenge.

The bitterly cold Arctic waters
around Hailuoto Island

create a unique problem
for engineers.

The causeway's two bridges
will stretch

700 meters across
the Baltic Sea.

When the water freezes over,

it forms a sheet of shifting
sea ice up to a meter thick

that can wreak havoc with
structures like bridge pillars.

To prevent this, the team must
anchor massive concrete bumpers

called ice breakers
into the seabed

that surround each pillar.

[ice creaking]

The bumpers' special shape
forces the ice up,

so it breaks under its own
weight, protecting the bridge

A chemical reaction occurs
when concrete begins to set.

It generates heat, which
workers must control

to ensure the concrete sets
without cracks.

The team pumps liquid coolant
through a network of tubes

installed inside the mold

to keep the concrete cool
