Coast (2005) s06e06 Episode Script

Welcome to the Baltic Sea and the sublime shoreline of Sweden.
For centuries Britons have charted a course to this glorious coast for its treasure trove of riches.
From bustling capital to sleepy village, the sea is in the soul of the Swedes.
The Baltic weaves its way around the myriad of inviting isles.
Britain is an island nation, but Sweden is a nation of islands.
The coast runs deep in their soul.
They come here to let their hair down, to unleash their inner Viking.
And now we're here to meet the Swedes.
To investigate the last days of sail, Dick reaches dizzying new heights.
lt's a very long way up.
Now l know why l didn't join the navy.
NlCK: Timber! Alice learns how Sweden keeps Britain's builders beaming.
So much for the forest being an oasis of calm.
This one's absolutely deafening.
NlCK: Mark's aboard the world's most stunning shipwreck.
This is the Tutankhamen of maritime archaeology.
NlCK: And l toast farewell to summer.
Skal.
Swedish style.
This is Coast and beyond.
Sweden, a country in love with its coast.
An elegant capital built on the water dances to the rhythms of the sea.
For centuries Britons have partnered the Swedes in a love affair with their shore.
From the island that inspired ABBA to a mysterious connection between Britain's Highlands and Sweden's High Coast, we're all linked to this majestic landscape.
Long before the flatpack furniture boom, we came here for wood to build our houses.
And Swedish iron was at the cutting edge of our industrial revolution.
Like us, the Swedes treasure island life, a land of adventure with a wild spirit.
We're in search of our bonds with a people who know how to party.
(Singing in Swedish) Skal! We've crossed to the Baltic Sea for an adventure along Sweden's shore.
Our destination is Stockholm, but we begin at Hogbonden in the wild north.
The Swedes call this their High Coast.
l'm on Hogbonden, a rocky outpost on the edge of a vast Nordic wilderness.
Europe doesn't get much more isolated than this.
And what splendid isolation it is.
- Hello there.
- Oh, hi.
This is absolutely wonderful, isn't it? Now, l've heard that Sweden can be quite cold in winter.
But now its warm, it's sunny.
ls this when you come out of hibernation? Yes, it is.
We love the summer.
lt's the feeling of freedom.
lt's lots to do by the sea.
We go to the beaches.
We go out in the nature.
We take saunas.
NlCK: Sauna? l've only just arrived and we're about to strip off.
Still, the picturesque steam house is irresistible.
Not sure l like the look of the plunge pool, though.
Last year, the sea between here and the mainland froze solid.
Fortunately, it's summer now.
Looks deceptively blissful, doesn't it? Time to get changed.
- lt's hot up here.
MAN: Yes.
- My specs are gonna start melting soon.
MAN: lt's a matter of humidity.
You can put some beer on the stones, get a nice smell and raise the temperature to about 70 degrees.
And then l guess there's a You can smell the kind of hoppy You feel it first now, being on top.
(Sighs) lt's a kind of beer massage.
lt's wonderful.
After steaming in alcohol, a sobering experience awaits.
We're 350 miles further north than Aberdeen.
This'll be chilly.
(Yells) l'm turning into a human iceberg, so l am getting out.
Well l've had my ritual sauna and dip in the Baltic, and l feel suitably Swedish, ready for an epic journey.
When the Swedes aren't in the Baltic Sea, they're either on it or they're beside it.
From north to south, this coast is peppered with islands, a paradise of private hideaways.
The lsle of Viggso was the perfect refuge for a world-famous pop group.
Hi.
My name is lngmarie Halling.
Waterloo Couldn't escape if l wanted to Back in the '70s l used to do make-up and hair for a group called ABBA.
Promise you'll love me for ever more Here comes this band dressed in costumes that no one ever had seen before.
They were really crazy.
During these hectic tours they did, they really needed a place to be, a place to hide out, so they found this place called Viggso a gorgeous place, and this is where they could be, just hanging out, drive around with their boat, swimming and fishing and having a good time.
Not doing anything in particular.
We're good at that, just being.
Knowing me, knowing you Ah-ha A lot of good inspiration came from this island.
Knowing me, knowing you Ah-ha This little writing hut, which belongs to Bjorn, was a good place for them to sit and find the songs.
Knowing me, knowing you lt's the best l can do So welcome to this little famous house out on Viggso, the writing hut.
There used to be a little piano here.
That's what they needed to be able to write songs like Dancing Queen.
ABBA: Dancing Queen Well, back in the '70s, the trees weren't this high.
No matter what, this is a very inspirational view.
Even today, l think.
lt's great.
You can dance, you can jive Having the time of your life Ooh, see that girl Watch that scene Dig in the dancing queen NlCK: We're travelling along the edge of the Baltic Sea, heading down Sweden's coast making for Stockholm.
But l can't resist stopping off to explore the High Coast.
These spectacular highlands don't just resemble Scotland.
There's a mystery locked in this landscape that links the Swedes to the Scots.
Cliffs, headlands, islands, pretty villages, the Hugge Kusten, the High Coast, is everything l could have hoped for.
lt's wonderfully picturesque, but there's more to it than meets the eye.
This shoreline is on the move, rising from the sea.
This coast is lifting upward at a rate of nearly one centimetre a year.
Within a few generations, the coast has risen up, cutting off villages from the sea and turning bays into lakes.
At the peak of a mountain, there's the highest beach in the world, 286 metres above the water and still rising.
To unravel this geological puzzle, l'm crossing one of the largest boulder fields on earth, down to sea level to meet park ranger Milly Lundstedt.
What a wonderful beach.
lt's got these typical wave-smoothed boulders on it, hasn't it? - Worn by the accent of the water.
- So rounded.
- Here you have a really nice stone.
- That's a classic example, isn't it? This is a huge beach.
lt goes back such a long way.
l'm taking my smooth sea-worn rock to compare it with the stones further inland, pebbles of an ancient shoreline left stranded as the ground rose up.
MlLLY: And you can feel that this is like an older beach.
You can see the likeness between those stones.
lt's smooth, rounded.
NlCK: So this one too came off a beach? Yeah.
lt's both beach stones, actually.
But far several thousand years ago.
NlCK: Heading away from the coast, we're still striding over the old sea bed.
Odd.
This beach is going on forever.
We've been walking for at least 1 5 minutes since we left.
How far up this cliff did the water use to come? MlLLY: Well, actually, the water, the sea was covered whole of this cliff.
You're kidding? This was completely underwater? Yeah, it was completely underwater.
NlCK: To reach the only land that wasn't once at the bottom of the sea we've got to climb a mountain, a ride to the highest beach in the world in style.
Great.
This is the strangest trip to the seaside l've ever taken.
lt's really nice to take a ride, no? NlCK: To see why this land's rising, we're taking a trip back to 20,000 years ago.
Then Scotland and Sweden were covered in ice.
The frozen straitjacket over Sweden's High Coast was two miles thick, pressing down on the earth.
When the ice melted, that weight lifted and this landscape started to spring back upwards.
Because the ice was so thick here, northern Sweden's now rising almost six times faster than Scotland.
These hills grow about a centimetre a year, but once the peaks were at sea level, surrounded by water.
So we're about to land on top of a former island.
Exactly.
9,600 years ago, actually.
What a strange sensation.
What an enormous view we have.
lslands, peninsulas, forests, little village down there.
lt's beautiful, isn't it? But what did this all look like 1 0,000 years ago? lf we were standing exactly here 1 0,000 years ago, we're actually standing on a beach.
- Right here? - Yeah.
On the highest shore line in the world, actually.
And when you look out, you see the sea and small islands, a few of them only.
Which have become the tops of mountains now.
Yeah, exactly, because of the land uplift, so And how much has it come up in total, where we are now? Well, from the sea level today and what we're standing today is 286 metres, and we're still rising.
NlCK: This landscape's still recovering from the lce Age.
These hills really are alive, springing upwards from the sea.
We're standing on the bounciest beach in the world.
Yes, correct.
NlCK: The Baltic is a curious sea all round.
lt's almost land-locked, more of a lake, really.
Rivers pour fresh water into the Baltic, diluting the seawater.
Because it's not very salty, unlike the seas off Britain, it ices up.
For months, much of the Baltic is frozen, so Sweden employs a fleet of icebreakers.
They forge on through the almost endless winter nights, keeping the Baltic Sea open for trade.
For centuries they've been shipping one of Sweden's greatest natural resources to Britain from the Port of Sundsvall.
ln a nearby forest, Alice is exploring why there's more to Swedish timber than flatpack furniture.
ln the second half of the 1 9th century, Britain was Sweden's biggest customer, so if you live in a Victorian house, there's a very good chance that the beams and floorboards are made of Swedish timber just like this.
From the forests, logs were floated down rivers to sawmills that used to line the coast.
Swedish exports provided the planks, the pit props and railway sleepers for Britain's industrial boom.
And we still want these trees.
They grow slowly in the cold climate, making the timber strong.
So much for the forest being an oasis of calm.
This one's absolutely deafening.
And it's incredible watching the speed and the scale of this destruction, but it's sustainable.
This forest is being cleared this year.
ln a couple of years' time, it'll be replanted.
Felling 1 00 trees an hour, the high-tech harvester cuts the precise lengths ordered by the sawmill.
Today it's for doorframes and decking, much of it heading our way.
Back on the coast, the log pile grows to feed the automated production line.
Only a few people are needed to transform a forest into cut timber.
lt's extraordinary.
We're looking out at an ocean of logs.
Yeah, you know, this is a pretty large mill, so we will process around 1 ,000 logs per hour, so all the logs you will see here will be consumed in one and a half weeks.
ALlCE: Half of the output of this mill is for export to the UK.
So within the space ofjust a couple of weeks, a tree that was once standing in a Swedish forest can be brought here, converted into sawn timber and loaded onto a ship bound for Britain, to end up perhaps in a builder's merchant somewhere near you.
NlCK: Sweden's east coast is a wild frontier.
People cling on as best they can.
Rare white-tailed sea eagles hunt along these unspoilt shores.
Heat stored in the sea during summer keeps the coast relatively warm in winter, making it attractive to animals, like the moose.
ln the frozen north, scientists are studying how moose head seawards when the temperature drops.
My name is Goran Ericsson, l'm a professor in wildlife ecology, and one of my topics is studying moose above the Arctic Circle here in Sweden.
Above the Arctic Circle there's very few roads, there's rough country, a lot of mountains, a lot of creeks.
Of course, we do the field work from ground, but instead of walking for a couple of weeks, we use a helicopter for a couple of hours.
When winter comes, there will be three or four feet of snow, so then it's a real hostile environment, so many of the moose will leave this area and start the migration towards the coast.
(Whispers) Look.
Look at the female trotting to the right.
She has a calf behind her.
They haven't spotted us yet, so we're safe here.
There comes the big bull, taking it slowly, following in the scent of the female to see what's happening here.
During wintertime we put collars on the animals, and the collar units are a combination between a GPS and a cellphone that's transmitted via a link out to our computers.
This is one of the ones we use in research.
He's about six years old.
He's probably in his prime age.
l would estimate that it's about 700, 800 kilos.
The reason they load up fat is as an energy resource that it can sustain and survive the winter.
But it also helps them to conserve the heat, so they're easily handling minus 35, minus 45 Celsius.
The river valleys and rangers are extremely important.
They will funnel the moose from the mountains towards the coast.
The environment is hostile.
There's not so much food.
lf you move out from the mountainous areas to the coast, there will be less coldness and probably more food for them.
(Whispering) What a great day.
Wow.
NlCK: Continuing my Swedish journey, l'm heading for the remote Hornslandet peninsular.
They've been catching salmon and herring in the waters off Hornslandet since the lron Age.
An ancient tradition is preserved behind the fishermen's huts with a strange spiral of stones.
For centuries they've practised a mysterious pagan ritual here.
Fishermen are a superstitious lot, and this labyrinth is one of their sacred places.
lt probably dates from the centuries when Hornslandet was still an island and fishermen used to walk the stone maze to bring them good luck on their fishing expeditions to ensure big catches out at sea.
But the fishermen didn't just rely on a pagan god for a decent catch.
This weathered timber chapel has been standing on this stony beach for over 200 years.
Generations of pious fishing families have passed through this very simple sanctuary.
lt feels very quiet and calm, bit like a ship in dry dock.
We're leaving the Swedish mainland behind, travelling some 60 miles offshore to a group of rocky outcrops, the Aland lslands.
There's an extraordinary story that links these small isles not only with Britain but Australia too.
An unlikely seafaring connection between the British Empire and Aland has brought Dick here to explore.
DlCK: ln summer, Aland's hundreds of tiny islands attract Scandinavian holidaymakers by the boatload.
Charting a course around these rocky isles is tricky for skippers today, but 1 50 years ago, without navigation aids, it was treacherous.
So this pilot station was built when Aland began to emerge as a rising power in the Baltic Sea trade.
There were four pilots stationed here, and it was the job of those guys to ensure the safe passage of the ships through these rocky outcrops, and there was plenty of traffic to keep them busy.
The Baltic is notorious for its misty moods, and ships, rocks and fog don't mix.
No wonder they invested in a warning system.
Apparently, this is the only operational steam fog horn in the world.
How's it working? Well, we have this engine that is running this air compressor, and now it's pumping into the tank.
And then we've got this pressure metre that we can see.
How do you know when it's ready? When it reaches one bar on the red and then it goes off.
- lt's quite close.
- Ten seconds and it will go off.
- Ten seconds? - Yes.
(Fog horn blares) What an amazing noise.
lmagine if you were a fog-bound scared sailor, that must have been music to your ears.
The Aland lsles are home to a proud seafaring people.
Around 90 years ago, one of those merchants hatched an ambitious plan to plug Aland into the wealth of the British Empire using some very big boats.
ln Mariehamn, one of these mighty ships still rests at anchor.
What a gorgeous vessel.
This was one of the last commercial sailing ships.
She may look like a 1 9th-century relic, but this 20th-century beauty held her own against the steamships.
This is the last word in wind-powered transport, the final hurrah of sail.
As late as the 1 940s, these vessels still managed to give steamships a run for their money.
The world knew them as windjammers.
And in the days of empire, they connected Britain to Australia.
MAN ON NEWSREEL: Australia is ready to cast its bread upon the waters.
Mountains of wheat from the outback plains stacked high in Port Victoria, South Australia, are destined to fill the granaries of the world.
Under their battened hatches are stacked the wheat cargos with which they will race round the stormy Cape Horn in their annual dash to Europe.
DlCK: South Australia was the start of the grain run, the windjammers'epic voyage to Britain.
lt took months to sail the 1 2,000 miles to Falmouth.
And yet steamships could do the trip to Australia three times faster, so why bother with these sailing ships? How did a business built on wind and sail rule the waves for so long? Henrik, hello.
Permission to come aboard, sir? Permission granted, sir.
DlCK: l'm meeting maritime historian Henrik Karlsson.
lt's an economical principle called ''just in time'' that we use today as well in logistics, because these ships were transporting grain from Australia to the UK or to Europe, and you could have loaded a steamship very quickly, like less than a month, but in order to take the grain to the mill and make flour out of it, it needs to ripen, so they used the ship as a storage during the voyage.
So it was good to be slightly slower? HENRlK: Yeah, and the voyage would take at least three months.
DlCK: They may have been slow, but these boats are more modern than they appear.
The Pommern was built in 1 903, her hull is made of steel, just like a steamship, but this windjammer's hung onto the romance of sail.
lt took age-old skills to handle them.
Those timeless traditions of the sea attracted a crew of youthful admirers.
People like Jocelyn Palmer, in search of adventure, paid for a passage on the last working tall ships.
Jocelyn lived in Australia, but she took the slow boat back to Britain where she'd been born.
We left on 1 1th March 1 948 from Port Victoria with a full cargo of wheat.
lt felt very remote being between South America and the Antarctic.
Huge waves and the ship just sailing through them, just like a little yacht in the sea.
And it got so cold, we looked out for icebergs, because a meeting with an iceberg would be pretty fatal, of course.
The sailing ships were considered something very romantic.
On a moonlight night, you could see the sails were snowy white.
And just that creaking of the timbers, you felt that the ship was alive.
And in those days, there was no other shipping there.
We were absolutely on our own except for the whales.
DlCK: Romantic it may have been, but it was no pleasure cruise for passengers or crew.
You went halfway round the world in these things, so we're talking about the elements, the weather.
- lt must have been hard to steer.
- Oh, yeah.
When a wave is hitting the rudder, you can feel it in the steering wheel, and that's why they lashed the people to the wheel.
- Tied on? - Yeah.
Well, they put the lashing around, across your shoulders, so you weren't swept overboard when a big sea came, you know.
There were also two men at the wheel in strong weather.
DlCK: Two of us? Right.
One night in the South Atlantic, Jocelyn witnessed the power of the high seas at first hand.
JOCELYN: Suddenly heard ''Bang!'' from up on deck and people running around, and some of the sails had just blown out.
That was why we heard a crack.
The sails were torn.
The wind was terrific.
lt was screaming wind and cold and it was really very unpleasant.
l think we were more worried about the crew because we knew they had to get up there and go aloft and take down the damaged sails and put up fresh sails to get the ship sailing properly again.
DlCK: Even on a calm day, going aloft is not for the faint-hearted.
lt's quite wobbly.
The boat's stationary now.
At sea this would be all over the place, and they didn't have harnesses.
Brave men.
Very good.
So you're almost on the top of the world.
That is something else.
(Laughs) lt's a very long way up.
Now l know why l didn't join the navy.
This feels relatively safe.
lf you look at where they were attaching the sail, they've got nothing below them at all.
- How do we get down? - Well DlCK: For the crew, it was a tough and dangerousjob, but there was no shortage of volunteers.
l have known many old sailors who started their seafaring life onboard ships like this, and they all said it was the best time of their life.
DlCK: Just a fortunate few are left who knew the windjammers in their pomp.
That great era of sail is passing over the horizon.
NlCK: Back on the mainland, ourjourney continues along Sweden's east coast.
Fingers of land poke out into the Baltic Sea.
lslands dot the shoreline.
lt's so peaceful here, you can almost hear your own heartbeat.
Odd to think this was once the beating heart of our industrial revolution.
Rock from near here helped lay the foundations for modern Britain.
Get it hot enough and this ore releases a metal, iron.
300 hundred years ago, this precious metal was shipped almost 1,000 miles to the mills of Sheffield and Birmingham.
But why were we coming all this way for iron? The town of Osterbybruk was well known to Britain's early engineers.
They needed a supply of iron that was pure enough to turn into steel.
ln the mid 1 8th century this foundry was producing metal of unrivalled purity.
This is the only forge of its kind in the world, and it's been making high-quality iron for 350 years.
Not a moment to trip over.
At the start of the industrial revolution, the Swedes had the technology and the premium-grade iron to hammer out a world-beating product.
Whoo! That was impressive.
Good heavens.
This Swedish iron helped put the ''great'' in Britain.
As we head further south, we reach the Stockholm archipelago.
We're about to arrive in the grand coastal capital, Stockholm itself.
A third of this city is water.
Boats and bridges unite settlements which originally grew up on separate islands.
Stockholm is a city of the sea.
The sea reaches from the heart of the inner city here all the way out to the wider world.
The power of the sea is written into the DNA of Stockholm and into the psyche of its people.
The elegant buildings of the old town bear witness to Sweden's rich history of trade.
Stockholm's heritage is almost entirely intact because the city wasn't bombed during the Second World War.
But the Swedes did play a pivotal part in the conflict.
Back in the dark days of the Second World War, the city was alive with intrigue.
Sweden was neutral and Stockholm was open for business, with both sides.
The Swedes didn't fight, but they did trade, with the Allies and the Nazis, double-dealing that has Alice intrigued.
ALlCE: l'm on the trail of a rarely told tale of industrial espionage, a connection to this coast that was crucial to victory in the Second World War.
The Swedish were the world experts in producing a vital component of the machinery of war, without which a country's war efforts would have literally ground to a halt.
Both Germany and Britain desperately needed Swedish ball bearings.
These tiny balls of specially hardened steel contained within bearings were the key components allowing moving parts in planes and tanks to rotate and not seize up.
Without ball bearings, weapons production would grind to a halt.
Churchill knew that Britain's future and the freedom of Europe revolved around these steel spheres.
The self-aligning ball bearing was invented by Swedish engineer Sven Wingquist in 1 907.
By the start of the Second World War, the British depended on the Swedes for their supply of ball bearings.
ln the 1 940s, Sweden was a neutral country caught in a vice between two power blocks.
The Nazis had surrounded Sweden.
The country could still trade, but the German stranglehold meant the Swedes were wary of doing business with the Allies.
Diplomats were sent to Stockholm in a desperate bid to get ball bearings back to Britain.
l'm with war historian Nick Hewitt.
So, Nick, these are the precious objects.
NlCK: Absolutely.
These are they.
This is the ball inside, this is the bearing and that would be used in perhaps a reasonable sized piece of equipment.
So what was the range of machinery these ball bearings might have been used in? Absolutely everything, from radar sets, to maybe the joystick of a Spitfire.
And the undercarriage wheels of the same aircraft go up and down inside the wings, and you need bearings to do that.
And you think about a turret and the way that turns around, you need bearings to do that too, so you can possibly argue that you couldn't have won the Battle of Britain without ball bearings.
ALlCE: To keep Britain's weapons production moving, the big guns weighed in to strong-arm the Swedes into playing ball and make more of their ball bearings available to the Allies.
This is a telegram, and it's a telegram to the president of the United States, President Roosevelt, from the prime minister, Winston Churchill.
These are two of the most powerful men in the world exchanging communications about ball bearings.
Such a strange story.
And what they're saying is, firstly, we urgently need to get out of Sweden ball bearings in particular.
What the British are asking the Americans, what Churchill is asking Roosevelt for, is to apply pressure using 30,000 tonnes of oil a quarter that the Swedes are getting from the Americans.
lf the Swedes refuse to supply the ball bearings, cut off the oil taps.
lt's a bargaining tool, blackmail and bribery, basically.
ALlCE: Secret deals were struck to buy more ball bearings for Britain.
But to get them out of Sweden, Allied air crews had to fly through Nazi airspace.
As the war progresses, they're being attacked by radar-equipped German night fighters which can find them at night and shoot them down.
The only defence they've got is the speed and the altitude they fly.
ALlCE: This rare film shows a top-secret mission to Sweden, an RAF Mosquito repainted with civilian markings.
These super-fast fighter bombers were converted to carry cargo, including people, strapped in their bomb bay.
But planes alone couldn't bring back enough ball bearings and Nazi control of the Baltic sea lanes seemed absolute.
One man, an unsung hero, thought differently.
There was a remarkable man called George Binney.
Which one's him? George is in the middle with the pipe.
ALlCE: Right.
NlCK: He's a civilian.
He's out here before the war.
And he's involved in the steel industry, so he knows Scandinavia, he has the right contacts.
He comes up with an alternative plan, which is to use fast military patrol boats known as motor gun boats.
ALlCE: These fast boats had a shallow draft, so they might just skirt over the German mines.
Success would demand courage.
George Binney hand-picked their crews.
Only the most able made the grade.
Many came from the merchant fleets of Hull, young men, mostly single, who might never see home again.
lt must have been incredibly dangerous sailing a boat like that through the naval blockades.
These are not built for rough weather, for a start, they're prone to mechanical failure, their engines break down a lot, and they're also vulnerable to the Germans.
Two of them are sunk out of five, which is quite a high attrition rate.
These sailors were running huge risks to get the ball bearings out of Sweden.
Very, very big risks, yeah.
lt's a dangerous covert operation.
ALlCE: Right under the nose of the Nazis, hunted by sea and air, these brave crews pulled off some of the most vital missions of the war.
lt's a sobering thought that the fate of Europe once revolved around these bearings, which kept the machinery of war running on both sides, but it was the bravery of the Allied airmen and sailors that kept the Swedish supply of ball bearings rolling into Britain.
NlCK: The Swedes love their coast and its wonderful isles.
Stockholm is part of a vast archipelago.
Thousands of rocky outcrops are scattered far out into the Baltic Sea.
Stockholmers call this their Skargarden.
''Skar'' is Old Norse for ''small island''.
So Skargarden translates roughly as Garden of lslands, and this is some garden.
Little boats ply the waters and traditional wooden houses dot the shore.
This is Stockholm's depressurisation zone, where city folk come to relax.
l'm here at the end of August.
The long winter nights are looming.
So the Swede's celebrate summer while they can, with a party to mark the passing of the season, a brief return to their Viking roots and a bit of craziness by throwing a crayfish party.
Every year they say goodbye to daylight with an outdoor feast.
l've been invited to one by Jessika Gedin.
She's offered to give me a beginner's guide to throwing a crayfish party.
The upper classes started eating it in the beginning of the 1 9th century and everybody tagged along.
And now we have all these traditions with it.
We have the lanterns, the August moon, and you have the singing and the beer and the schnapps, and it's a bit like Christmas in the end of the summer.
NlCK: Why do you celebrate the end of summer? Why is that such a big deal? lt's not a celebration, really, it's sort of a sad festival, in a way, because we've been longing for the light for such a long time.
l mean, we spend like six months in complete darkness in Sweden, so when the summer comes we go like crazy, and this is the last party.
lt's sort of melancholic but it's fun at the same time.
- Lead on.
- Sure.
Come on.
NlCK: lt seems drinking and singing matter as much as the crayfish.
(All singing) Sounds as if the party's already started, Jessika.
JESSlKA: That's good.
Wow.
(Singing) NlCK: To get me into the swing, l'm relying on Hans Rosenfeldt.
You can't have a crayfish party without the singing and you can't have the singing without the schnapps.
So that's how it all works together.
And the schnapps is there just because you sing, and every song with a drink.
The song you were singing when we came to sit down, what was that about? - lt was actually about schnapps.
- lt was a drinking song? HANS: lt was a pure drinking song.
Let's say that everybody has it.
lf you have a crayfish party, you sing Hej Languor.
(Singing in Swedish to the tune of Twinkle, Twinkle, Little Star) ALL: Skal! NlCK: l recognised that.
HANS: You recognised that.
- Twinkle, Twinkle, Little Star.
- Yes, it is.
Nursery rhyme.
NlCK: As long as the song has the word crayfish in it, you can have a drink.
Yeah, basically.
Actually, you drink even if it hasn't got the word crayfish in it.
As soon as someone takes up a song, at the end you drink.
So, Hans, here we are sitting on the most coastal location you can imagine, on a grassy promontory with the Baltic wrapped around us.
Does the coast mean a lot to Swedes? l think it does.
We have a lot of it.
l'd say most people have a relationship to the coast.
You can light a fire, you can drink your coffee, you can eat your lunch and then you can go back in to your more square-formed life in the big city again.
So l think it's a huge freedom factor in the coast in Sweden.
(Singing) ALL: Skal! JESSlKA: We worship summer, l think we do.
We're like asleep for six months when it's dark and when we're working, and then, you know, suddenly spring comes and everything changes.
- Explodes.
- So l think this is sort of part of it.
This is sort of what we consider being Swedish, l think.
(Singing in Swedish to the tune of Ding Dong Merrily On High) NlCK: How do l go about breaking into one of these delicious-looking fish? - Would you give me a demonstration? - Yeah, sure.
You just pick them up like this, turn it over and then you just basically suck.
- You like that? - Well - l would say no.
- Perhaps with a bit more practice.
Sounds like l'm just sucking up a mouthful of seawater.
(Singing) NlCK: Blimey.
l can barely sing in English, let alone Swedish.
(Singing continues) ALL: Skal! JESSlKA: Your Swedish is pretty good.
NlCK: l got the last word anyway.
Stockholm was once the centre of Sweden's global sea trade, but today the majority of boats look for local business.
The sea's a highway here in the Swedish capital.
You hop on and off ferries, like that one there, as if you're getting on and off buses.
The water's a living space.
No wonder the Swedes take such pride in their coastal heritage and their maritime traditions.
But there are a few skeletons out there in David Jones's locker.
Mark has come to Stockholm harbour to investigate one of the world's most embarrassing naval accidents.
MARK: There's one remarkable shipwreck l've always wanted to set foot on.
Now finally l'm here.
lt's magnificent.
lt's the complete ship.
This mighty warship is nearly 400 years old, yet it's as if she was built yesterday, a wreck raised almost intact.
This isn't a re-creation, it's the actual ship.
The Vasa was meant to spearhead Sweden's navy, but she sank in 1 628 on her maiden voyage.
How did the Vasa, the king's grandest warship, keel over and sink on her first outing? l'm going to the site of Sweden's great national embarrassment with historian Marika Hedin.
MARlKA: 1 0th August, 1 628.
lt was meant to be a moment of natural pride and grandeur, and it was for about 30 minutes.
So where exactly did she go down? Well, she was found over there, where the water is about 30 metres deep.
So that meant that when she went down, you would have seen the masts sticking out of the water, flags and all.
- That was a very public spectacle.
- lt was.
lt was a public fiasco.
MARK: This magnificent ship sank in the most humiliating fashion.
The Vasa never got out of Stockholm harbour.
Shamed by the disaster, Sweden forgot the Vasa, but the Baltic Sea preserved her in its cold embrace for over three centuries.
The reason she sank was waiting to be discovered.
Finally, in 1 956, amateur archaeologist Anders Franzen went fishing for the wreck.
MARlKA: He rowed around in his little boat in the harbour looking for blackened oak, which would have been a sign that he would have found the Vasa.
And eventually he did come up and found something in 1 956, and that, of course, was the starting point for one of the greatest adventures of maritime archaeology in the world, the salvage.
lt was an extremely complex operation, no one had done anything like it before, so everything that was tried was experimental.
And the divers worked in very harsh conditions, through water, digging tunnels under the wreck, so that she eventually could be lifted through steel wires up towards the surface.
So after over 300 years, the Vasa was to break through the surface again.
That's true, on 24th April, 1 961 .
lt was a world event.
MARK: Were the divers worried that as she came up she would break apart? MARlKA: No one knew how strong she would be, and, of course, all of the iron bolts had rusted away, and attempts had been below the surface to strengthen her, but still we didn't know if she would hold together.
But she did.
She was very well built in some respects.
- And very little used, of course.
- That's true.
MARK: So she was able to be, as it were, brought back on her own buoyancy.
MARlKA: That's true, that was the last trip that the Vasa would ever make on her own, and then she was put into the conservation process, which took some 1 7 years.
MARK: To find out why she sank in the first place, l'm stepping back in time, nearly 400 years.
She's beautiful, isn't she? And this is actually a rare privilege.
Only heads of state and the occasional maritime archaeologist are allowed on board these days.
MARK: The Vasa is so well preserved, you can still piece together the evidence of her sinking.
Be careful here.
lt's The beams come down quite low.
lt gives an impression of what it was actually like down here.
Yes, it must have been very crowded and quite dark.
MARK: So on that fateful day, they fired the cannons? Yes, they did, because they were sailing out and this was a moment of triumph, so they fired a salute, and all the cannon ports were open.
And this was probably an error of judgement, because when the ship keeled over then, the water came in.
So you can just imagine the water gushing in.
Yes, it must have been quite scary.
So she literally just fell over.
Yes, she did, straight into the mud.
MARK: The open gun ports meant water flooded in after a simple gust of wind made the ship roll over.
The fatal mistake was in the original design.
You can see she's very narrow in the stern, and this made her very unstable.
Surely there were lots of other boats sailing around of this size and they weren't capsizing all the time.
No, that's right, there actually was a sister ship to the Vasa which had almost the same dimensions, the Apple.
And she sailed off a year after Vasa sank, but she was a little more broader, she was about three and a half feet broader, and that made all the difference.
But l think the Vasa, if she had made it out into the archipelago, and then she would have been loaded with materials and with more men, she would have been heavier and more stable in the water.
So it wasn't just a bad design, but it was also bad luck.
Really bad luck, l would say.
MARK: lt's ironic that this Swedish naval disaster has left us with the most important shipwreck ever discovered.
This is the Tutankhamen of maritime archaeology.
NlCK: On ourjourney along the shores of Sweden we've discovered links between us and our coastal cousins in Scandinavia, the age-old trade in timber and iron and a passion for messing about in boats.
Once ashore in the city, the hectic traffic's also strangely familiar but somehow different.
There are many things we share with Sweden, but after 3rd September, 1 967, there was one less.
That's when Swedes switched from driving on our side of the road, the left, and changed to the right, to conform with the rest of mainland Europe.
l'm used to biking through London, but switching to the right-hand side makes things a bit hairy.
lmagine what it was like back in 1 967 when the whole country changed lanes overnight.
Potential chaos.
Well, the radio said l had to stop, l have to stop for a while here.
l shall then be shown onto the other side of the road.
l then have to stop there and at five o'clock we all move off driving on the right-hand side of the road.
Shall l go over that side? Thank you.
lt was known as H day, after the Swedish word for right, ''hoger''.
They cleverly combined the capital H with an arrow changing lane to create a logo for switchover day.
But there was more to H day than a logo.
The government embarked on a massive programme of advertising and education, from highway code lessons for children to some rather alarming stunts.
Finally, on September 3rd, everything was in place, the roads altered, the signs ready, 1 0,000 police and troops deployed onto the streets.
But still no one knew how many people might become victims of this right-hand revolution.
This is the scene at five o'clock in the morning on 3rd September, 1 967, as everybody switched lanes.
Amazingly, H day went without a hitch.
ln fact, surprisingly, the number of accidents slightly decreased.
So might we one day find ourselves switching lanes too? On the highways worldwide, sticking to the left puts us in the minority, but on the seaways it's a different story.
The rules of navigation that apply around the globe owe an awful lot to the pioneering efforts of the British to impose order on the sea lanes of the world.
lronically, when proposing navigation laws for steamships in the 1 9th century, Britain decided ships should pass each other not on the left but on the right.
Over the years this British ''keep right'' regulation became adopted as the global standard for the seas.
Britannia's rule does in fact rule the waves.
Even out here, on the edge of the Baltic Sea, some thousand miles from our own islands, you can sense the influence of Britain reaching far beyond our own coast.
We're a seafaring people, but we share our story with distant shores.
