All language subtitles for Italys Invisible Cities Series 1 2of3 Venice 720p HDTV

Italy. I just love this country.

The people, the places, a history
that reaches back over 2,500 years.

From the birth of the Roman Empire,

through the glories of
the Middle Ages,

to the flowering of the Renaissance,

its achievements are
just breathtaking.

But behind its glorious facades,

so much of that invention and
creativity still remains invisible.

Look at that.

I'm exploring three of my favourite
Italian cities to discover how their

hidden treasures played their part
in the making of Italy,

and of Western civilisation.

I'll be working with historian
Dr Michael Scott

to uncover the invisible layers
of Italy's past in Venice,

in Florence and in Naples.

You've got Nero murdering his mum...

Using the latest
3D scanning technology,

we'll reveal the secrets of
how these cities made Italy

a powerhouse of the Western world.

This time, I'm exploring the hidden
secrets of one of the world's most

remarkable cities - Venice.

Our scans will strip back the layers
of history to reveal how Venice's

beauty once masked
a ruthless secret state

and a world of excess and vice.

The city was devoted to
erotic pleasure.

Wahey, whoa, wahey, there we go!

We'll see how the Venetians
battled the plague...

Welcome to the island of
the Black Death.

Right, we're off, OK,
back, back, back.

..how they build their city around
money-making...

We were the biggest traders and
marketers in the world.

..to create one of Europe's
mightiest empires.

The smell of power is
reeking in the air.

And for the first time,
we'll use virtual reality.

And see how the Venetians
turned a muddy swamp...

I'm sinking, you can see that.

..into this watery wonderland.

The second leg of our journey
through invisible Italy begins at

the airport taxi rank.

Benvenuto a Venezia! Grazie!
How are you doing? You all right?

Look at this beautiful boat.
Welcome, shall we take that?

'My expert guide, Dr Michael Scott,
is travelling in style.'

How do you do? Come on in,
welcome aboard.

It's a hell of a way to arrive,
isn't it?

This is the way to arrive in Venice.

There it is, there it is, the most
famous cityscape in the world.

Certainly one of the most unique
places in the world.

Absolutely. I mean, unless
we've got some sort of sub-aqua kit,

what are we going to be
looking at here?

Well, we're certainly going to be
going underwater,

but we're going to be also,
crucially...

I'm just going to stop you right
there. We're going underwater,

are we? Oh, we're going underwater,
yeah. OK. You know. But we're going

to be exploring what it is that
makes Venice possible.

Venice is built in 210 square miles
of shallow lagoon.

Most of its 118 islands are just
inches above sea level.

To get us started,

Michael's going to show me what this
corner of north-east Italy looked

like when the first Venetians
came here.

We're just two miles from
the centre of the city.

You have your feet on
the origins of Venice.

This is Venice, this mud,

this is what Venice
really stands on.

Crab, big crab.

We're in a lagoon. Yes. Protected by
a big sand bar and to sea.

But 80% of it is this stuff - the
salt marshes that are either just

above... I'm sinking,
you can see that.

I am sinking. And I weigh marginally
less than a city.

The first Venetians were Romans, who
started building here in the fifth

century AD, when the empire was
in a state of collapse.

This strikes me

as a crazy place to build anything,
let alone a city.

You have to be pretty desperate...
You do.

..to want to make it here.
That is due to huge invasions that

are coming in from people
like the Visigoths,

people like Attila the Hun,

are coming in and sweeping through
the northern Mediterranean.

And so, in northern Italy, people
are looking for somewhere safe.

This muddy marshland inspired the
Venetians to develop new engineering

skills. They created one of the
finest cities on earth,

that would inspire poets
from Byron to Shakespeare.

I don't think you arrive anywhere
else in the world with this much

drama all around you. Byron called
Venice the paragon of landfalls,

and he's absolutely right.

There's so much drama,
histrionic level of drama,

as if a, sort of, mad genius
has come up with the idea.

'By the ninth century,

'while Alfred the Great was fighting
off the Vikings in England,

'Venice was emerging as a new power
in the Mediterranean.'

The communities living in the lagoon
had joined together to form the Most

Serene Republic of Venice -
La Serenissima.

CHURCH BELLS CHIME

Michael has me up at dawn
to avoid the crowds.

We are off to the most famous place
in Venice, the Piazza San Marco.

What you see before you is only
possible because of a whole set of

invisible magic tricks.

And we're going to have to employ
some of our own magic tricks

to make sense of this place. We're
going to have to use our scanning

team to the utmost to be able to
produce some really good scans

linking together the places that
we're going to be looking at

in some detail.

'Scanning this aquatic city is going
to be one of our team's most

'difficult jobs yet, but it means
they get to play

'with a whole bunch of new kit.'

We've definitely got quite an
ambitious amount of scanning that is

happening here in Venice. We've got
our mobile mapping team, who are

hoping to capture the whole of
the Grand Canal.

We've got our underwater team,

and then we've got
the terrestrial scanning

that we're doing for some of the
squares and churches that pepper

their way across Venice.

So, all of these should hopefully
kind of come together as, you know,

a monumental map of Venice.

Michael's taking me up to see
his favourite view of the

Basilica di San Marco...

Ah, here we are.

..the cathedral
at the heart of Venice.

Goodness me.

I'm tempted to say, "It's a mess!"

I mean, it's beautiful, of course
it's beautiful, very striking.

But, if somebody built something
like that today,

they wouldn't really
get away with it.

They've certainly gone to, sort of,
maximise every square inch.

The Venetians first built a basilica
here in the year 829,

to house the bones of
the gospel writer Mark.

Two Venetian merchants
stole his body from Alexandria

and brought him home
to be their patron saint.

And poor old Saint Mark wasn't the
only thing the Venetians pinched.

The ninth century is when Venice is
really starting to come together as

a city. And it's getting, sort of,
a sense of itself

and it wants all the trappings.

And then in the 11th century,
this magnum opus is consecrated.

But then, they add to it
over the years.

So, when Venice is, kind of, really
in full flood of... Mm. Well,

frankly, grabbing staff, they come
and slap it on St Mark's.

The horses that dominate
the centrepiece,

they're nabbed from Constantinople.

All these columns that you see
along the front,

they're all kind of Oriental columns
from the east that they brought back

from different parts of the world.

Every bit of this building screams
the fact that Venice went elsewhere,

grabbed stuff and
brought it back to Venice.

And displays it proudly, this is
looting as proof of dominion.

There's stolen booty
all around Venice,

from its conquests in Greece,
Croatia and Cyprus.

Even the symbol of St Mark,
the bronze Lion of Venice,

was originally an ancient winged god
taken from eastern Turkey.

'Everywhere you look in this city
reminds you just how powerful

'and wealthy Venice became
in her heyday.'

Our first scans capture the smallest
details of the loot on St Mark's,

and build out from there to the
grandeur of the Piazza and beyond.

The scanners are going to create
a giant 3D model

of the heart of Venice.

They'll build it onto
the existing digital map.

When complete, this will be an
accurate snapshot of this slowly

disintegrating city.

An invaluable tool for
archaeologists,

engineers and conservators.

And it'll help us reveal the
invisible secrets of Venice.

While the scanners get on with
their epic assignment,

I'm off to meet Michael.

He's going to show me how the
Venetians managed to build their

city in this muddy marsh.

He is with a team of
underwater archaeologists

and restorers repairing
a section of canal wall.

Sadly, I'm not qualified to dive,

so the intrepid professor will be
slipping into neoprene

for both of us.

Michael. Ah, good morning.
Good morning. Shall I hop on?

Come on board, come on board,
welcome.

What are you doing down here? OK.

So, the newest member of our
presenting team is here.

What is this, Blue Peter? So, you'll
be going down to the bottom of the

canal, basically, just to look at
the bed, see what's there.

And you're examining foundations,
are you?

We're going to be looking at
some foundations.

What's all this, "we"?
You keep saying "we".

Well, "we", because of the wonders
of modern technology.

Yes. You, too, are going to be able
to share in what I see down there.

I'm so pleased to hear that,
the "we" has been worrying me.

Not in the water... Well, the "wee"
could still be worrying you.

We are going to take
some precautions.

So, we are going to be spraying
medicated olive oil.

Oh, the last defence
against the superbug, good.

I have to admit to having been
in Venetian canals once or twice

before, sort of, in my youth.

Byron used to swim the Grand Canal
every morning before breakfast.

And look what happened to him.
Yes, died aged 36 of a fever.

So, yeah, there we are.

Listen, good luck. I shall be right
here, I shall be gunning for you.

Thank you.

Well, I can tell you, I've never
been more grateful that I've not

done a scuba diving course,

which means I'm exempt from
going down into the canal.

I am looking forward to this,
though.

I'm intrigued to see what Michael's
going to find down there.

Michael, just checking
you can hear me.

RADIO: 'I can hear you.

'I have to say, Xander, visibility
is not currently fantastic.

'You, literally, cannot see a thing.

'It's incredibly disorientating.'

The team has timed Michael's dive
at the turning of the tide.

As the water starts
to rush out of the lagoon,

it takes some of the silt with it.

'We're starting to get a little bit
of clarity now down here,

'which is really exciting.

So, I'm pressed up just against
the canal wall,

'the deep stone foundations
under the building.'

As the water clears,

it reveals the invisible foundations
of the Venetians' amphibious city.

'What we're looking at here is
there's some exposed tops

'of tree trunks.

'These ones here are
in fantastic condition.

'It's hard to believe this is wood
that is hundreds of years old.'

I can see them, I can see them.

A bit of sediment now,
but I got a clear glimpse

just about five seconds ago.

'The early Venetians took massive
wooden trunks between one and a

'half, two to three metres long,

'and they pounded them into the mud
along the boundaries of the area

'they wanted to build on.

'Now that secured the mud and gave

'them the beginnings of
a strong foundation.

'But, obviously, normally, wood
would not survive and yet,

'thanks to the anaerobic conditions
deep in the mud, where there

'is no oxygen -
these tree trunks don't rot.'

There's just tree trunks
holding all this up.

The exterior walls of
Venice's palazzos

are supported by thousands of
tightly packed wooden piles thrust

into the mud of the lagoon to
shore up the city's precious land.

It's an ingenious piece of
engineering that's kept the city

afloat for hundreds of years.

But Venice is under attack
by rising sea levels.

And the 30,000 boats rushing around
Venice every day

are making the problem worse.

The wash and the underwater waves
from their propellers are destroying

the canal walls and exposing
the ancient tree trunks.

They very quickly start to rot,
putting Venice in greater danger.

I'm leaving Michael to peel off
the neoprene to go and meet other

inhabitants of the lagoon, and
a genuine Venetian contessa.

Happily, Enrica Rocca is also
one of Italy's favourite chefs.

Bite into the head and
eat the tail.

'We meet in an area known as Rialto,
in one of Venice's oldest markets.'

We're going to buy a couple a few
ingredients and then we'll go to my

house and we'll cook a few things.
Fantastic. So, Xander,

you're going to have not only a food
lesson, but you're also going to see

how food relates to history,
to the history of the Serenissima.

Fantastic, to justify it,
there we are.

Brilliant, history through food.

Can we do history through booze
as well, I wonder?

Yes, of course. Oh! Come on,
we're going to have lots of booze.

Allora, Damiano. Mi da piacere
mezzo chilo di vongole.

Si. So, we're going to
get some vongole,

We're going to make you a nice pasta
with clams.

With the vongole of the lagoon.

Wonderful. OK. And the vongole
come from the lagoon?

From the lagoon. The lagoon was
the first source of food

for Venice.

Andiamo! You lead on.

Here we go, welcome to my home.

I feel like I've broken something!

This is my piece of craziness.

May I introduce you to Morella?
Nice to meet you. Piacere.

And Aldo. Piacere.

Piacere. Cheers. Cheers.

So, here we have sardines. Yeah.

We're going to make it taste
a little bit of the sea.

And you just put some egg,
breadcrumbs, deep fry it.

This is local, this is straight out
of the Adriatic. Yeah.

Straight out of the frying pan,
more importantly. Mm-hm.

That's delicious. Don't worry,
there's more coming. Yum, yum, yum!

'By the 13th century,

'Venetian merchants were exploring
far beyond the lagoon.

'They returned with fabulous tales

'and even more fabulous
things to eat.'

The most famous was Marco Polo,
who explored as far as China.

Go, on the table, very strong, go.

No. More, stronger, stronger!

That's it. Now you've opened it.

So, we started off with
our lovely sardines,

which are very much locally sourced.

We have now moved into things that
have been inspired by stuff from far

afield. Spaghetti, which we think of
as just, couldn't be more Italian,

doesn't really originate from Italy.

Pasta comes from Marco Polo,
from the east, from China.

Risotto, which we think of as
quintessentially Italian also...

Doesn't originate...
..doesn't originate in Italy.

What's happening here?

Basically, we have influences coming
from everywhere, that transform

themselves in what is today...

Venetian tradition.

But that I think is the key thing,
isn't it?

You made it your own.

You've, sort of, appropriated
things...

Yes, absolutely. And turned them
into heartfelt Venetian dishes.

Absolutely. We were the biggest
traders and marketers in the world.

Phew.

Smell. Mm. Because this
comes from the east.

'Venice grew rich by cornering the
European market in exotic foods and

'spices from Asia.'

It's gloriously salty.

Exactly. Delicious black pepper
as well.

At the time of the foundation of
civilisations

was salt, pepper, saffron, spices.

So, all these things, it turns out,
have come from as well.

They're not really Italian at all,
but they've been brought here,

they've been appropriated,
like so many other things.

And this is the great thing,
the chutzpah of the Venetians,

they've been hallmarked as
quintessentially Venetian,

quintessentially Italian.

And that's how they've been sold
to the rest of the world.

Just brilliant.
And delicious.

After last night's gastronomic
history lesson,

Michael is taking me to explore
the city's canals.

I'm starting to see how everything
in medieval Venice

was geared towards buying,
selling and making money.

'As Venice's
international trade expanded,

'the commercial area of Rialto
became more and more important.

'It's connected to the political
centre, San Marco,

'by one of Venice's
most visited landmarks.'

We're coming to the oldest bridge
across the Grand Canal, at Rialto.

So, this is something like this
sixth Rialto Bridge, which,

they nailed it in the 16th century.

Yeah, baby. With this extraordinary
structure,

which the people at the time didn't
believe could possibly work,

because it has no central support.

This was the genius invention of
somebody called,

if you can believe it,

Antonio di Ponte,
Antonio the Bridge Man.

He was Antonio Smith before
he built this, I imagine, wasn't he?

The brilliance of
da Ponte's engineering

is completely hidden from view.

The elegant arch directs all the
weight of the bridge onto massive

stone foundations on either side of
the canal.

And buried beneath them, more of
those preserved tree trunks,

6,000 of them under each bank.

The design is strong enough to
support the weight of an entire

street of shops.

Those wily merchants wasted
no opportunity to make money.

The scanning team is right behind us
on the Grand Canal.

To create a perfect digital
reproduction of this watery city,

the team has enlisted Federico,
a local scanning specialist.

Our scanner is quite static,
you know,

if you knock the tripod,
you ruin the scan.

Here we are on a boat.

How does that work, how are you
getting straight data and not wibbly

wobbly data? Yeah, we have
two informations,

one with the GNSS position,
the global position,

plus, inside of the system we have
a gyroscope and accelerometer

and we know exactly
what is the position

and the angle of the equipment.

The specially adapted scanner
is going to work its magic

along the entire length
of the Grand Canal.

The data will form the backbone of
our 3D model of the city.

This waterway has been bringing the
riches of the world flooding into

the markets of Rialto since
Venice's earliest days.

So, coming to Rialto today,

being surrounded by people from
all over the world,

it's just like Venice
would have been in its heyday.

From the 10th-11th centuries,

Venice is getting trade concessions
with the East.

By the 12th and 13th centuries,

it is the major power
trading with the East.

And from these, can I just
quickly ask, what's coming in?

Luxury things, silks, spices?

Absolutely. But everything
from humdrum wheat

and food supplies to gems,
to dyes, to silks, to fabrics.

They talked about the way
merchandise in this period

was flowing into Venice
like water from a fountain.

I mean, it's just this continual
rush of people and things.

This was the first place
you could write a cheque,

as a result of the needs of
all the people trading.

Of course, of course.

There's something in the blood,
there's something in the water,

that makes these people
incredible innovators,

incredible entrepreneurs,
incredible businessmen.

The 3D scan of the Grand Canal shows
how prosperous merchants packed

their grand palazzos and warehouses
along every inch of the waterway.

The shadowy outlines of boats
rushing past our scanners

are ghostly reminders of
centuries of commerce

that flowed along Venice's
trading superhighway.

Michael's taking me
down a side canal,

to a place that was home to
a group of immigrants

vital to Venice's
commercial success.

What we are looking for here
is a doorway...

..to another world.

Which is here.

Here it is. Aha.

What we've walked into
is the ghetto,

the Jewish ghetto of Venice,

the first ghetto in the world.

'In the 16th century,
Jews suffered widespread

'persecution across Europe.

'Venice was relatively tolerant.

'Jews were allowed to settle here,

'but they still faced
severe restrictions.'

From 1516 onwards, the Venetians
demanded that if you were Jewish,

you had to live in
the Jewish ghetto.

As a word, it gained negative
reputation, but it didn't begin like

that. Before it was used
as a ghetto,

it was the area of foundries,
smiths.

And the word in Venetian
for that is "gheto."

Gheto? Gheto. Jews were prohibited
from marrying Christians

and could only work in
a few designated trades -

services the city most needed,
like medicine and moneylending.

In the Middle Ages, Christians were
forbidden to charge interest.

So, the Jews came in very useful.

The Venetians borrowed their money,
but many also resented them for it.

The ghetto was a way to appease
Christian mistrust.

The doors were locked at night and
guarded by Christian soldiers,

so they were... Contained?

Contained. Yeah,
but on the other hand,

they're highly valued members
of Venetian society.

They're moneylenders.

They were absolutely fundamental
to making Venice work

as such a rich environment.

This tiny enclave was soon
home to around 3,000 Jews,

arriving from all over the world.

'Professor Shaul Bassi is going to
show me one of their synagogues.

'They're hidden away behind plain
exteriors at the top of the ghetto's

'overcrowded blocks.'

It's incredible. Welcome to
the German Synagogue,

the Schola Tedescha.

The German Synagogue.

This is probably 1528 or 29,
so 12 years into the existence

of the ghetto.

The oldest and also the sign that
the Jews at that point felt stable

enough to create a place of worship.

This was where they were going to
stay? Yes.

Shaul became fascinated by the
history of the ghetto while studying

Shakespeare's Merchant of Venice
and its Jewish villain,

the moneylender Shylock.

This would have been
Shylock's synagogue.

Since moneylending was
a prerogative of the German Jews,

if Shylock had been real person,

he would have probably
prayed in this place.

In this synagogue. Yeah.

The Jews weren't allowed to be
architects or builders,

so they had to employ Christians
to construct their synagogues.

And they weren't allowed to buy
land, so they had to carve them out

of the existing buildings.

All the buildings in the ghetto were
not the palazzos of the aristocrats,

they were actually poor housing
that was made available

to the first Jews.

And then later, when the community
was probably more prosperous,

they added all the gilding and this
wonderful elliptical women's gallery

that is a kind of imitation of
a typical Venetian theatre. Mm.

So, again, one can think of the
ghetto as a place of separation,

but can also very much think of it
as a place of encounter,

dialogue and exchange.

The scanners are stitching together
data from teams across the city to

create their colossal 3D model.

I'm off to see their
work in progress.

Oh, Matt, time for
a few more treats.

What have you got for me today? OK.
OK, so, here we are in Venice.

We're going to start today
with the Ghetto Nuovo.

We have the canals bounding
this area on all sides. Mm.

And as a result of that,

the buildings in here are
incredibly tall. Look at that, yeah.

They've ended up creating their
synagogues in these really quite

unique, quite...quite hidden away
and quite strange places.

And the upper floors.

Nestled in between facades,
in these strange shapes.

Extraordinary, isn't it?
So, we have the German one here.

And, actually, let's take you back
to street level here.

Up the passageway here, there is
another interior lurking.

This is the Levantine Synagogue.

The Levantines got a rather more
foursquare space to deal with.

They did, but it's still, you know,
quite a traditional apartment plot,

really. Complete with,
at the rear here,

just this little garden space.
Yeah. It feels very domestic.

Let's pop you inside. You know,
we just have this normal front door,

bit of a staircase...
Yeah. And then, suddenly,

we're inside this incredible
chandeliered space.

Oh, but it's beautiful, though.

It's an extraordinary privilege,
isn't it, with this technology,

to be able to go in? I mean, we look
from the street level and you see

these tenements,
people rammed into this tiny area

that they were allowed.
And yet,

here are the special spaces where
they were allowed to be themselves.

And these rooms of extraordinary
opulence. Mm-hm.

Yeah, these little jewels,
kind of hidden behind the facade,

not given any dominance
from outside. Yeah.

Suddenly, there's this one space
where they can, like you say,

be themselves and celebrate.

This is an enormously valuable tool
for just so many reasons.

We're building up this incredibly
extensive map of the city,

inside and out, from the water, from
the streets, from inside buildings.

And we're handing that over to
a team of international researchers

and it's helping inform
their knowledge of

the history of the city,

but also helping them
plan for the future.

Since medieval times,

Venice has absorbed the influences
of a fabulous melting pot of

cultures from all over the world.

When Charles Dickens
saw Venice, he said,

"Opium could not have fashioned
such a place." And he's right,

it does have this otherworldly,
hallucinatory quality.

But I'm getting a picture of
something much more determined,

much more driven, a sense of a city
pushed onwards, constantly,

by its entrepreneurial spirit.

The merchants shaped the politics of
the Venetian Republic.

The head of state
was known as the Doge.

His formal residence on
St Mark's Square

was built during
Venice's golden age.

It was begun in the 14th century

and completed over
the next 200 years.

This is the grand staircase of
entrance to the Doge's Palace,

and the smell of power
is reeking in the air.

It is just extraordinary.

I mean, one doesn't really know
where to look.

Every tiny part of it
is so exquisite.

So, as you walk up this grand,
monumental staircase,

you're greeted by Poseidon, god of
the sea, and by Aries, god of war.

And then as you head through
the portico,

you walk under the lion of
St Mark of Venice, the winged lion.

The message you're being given
is unmistakable.

It's clear, isn't it? But this is
a palace not really for a king,

the Doge wasn't really a king,

because Venice had
a very complex system

in which no-one person was
trusted with absolute power.

And it's more than a palace,
it's the government building,

it's the military HQ.

Our scans uncover the labyrinthine
internal structure of the palace.

It reflects the Venetian Republic's
complex political structure that

evolved over the centuries.

This is the room where Venetian
leaders gathered to elect the Doge.

He would then hold the position
for life.

Then there are grand halls,
for overlapping

and competing bureaucracies,
diluting his power.

There's the Senate,

the College,

the Council of Ten.

The members of these bodies and the
Doge himself were all drawn from the

most important assembly of all.

So, welcome, Xander,

to the chamber of the Great Council
of the Venetian Republic.

This is just astonishing.

53 metres long and 25 metres wide,

it is the largest room
in the Doge's Palace.

This is Venice.

This is the scale and magnificence

and the beauty with which Venice
does things.

You can tell where the big cheese is
sitting. Yeah.

The Doge is right there.

Now, who would be occupying this
space?

The Great Council. Now that is
members of every patrician

and aristocratic family in Venice
over the age of 25.

So, we're talking
a large number of people,

somewhere between
1,200 and 2,000 people.

And these guys see themselves as the
absolute bedrock of the Venetian

Republic. Right. It's their job to
look after the laws,

make sure stuff stays on track,
not allow him, the Doge,

to get away with too much.

I was just thinking as you were
saying that,

the guy sitting in a throne up there
their isn't really sitting that

comfortably. Look along
the top line around the walls.

These are portraits of
the first 76 Doges,

but if he ever over there in his
seat got a little bit lippy,

see this guy here?

The black curtain.

The Doge who tried

to take too much power.

In ancient Rome. we would call this
"damnatio memoriae,"

you're dammed from memory,
you're obliterated.

But in a way that preserves
the memory forever.

So, that is in
the corner of the eye.

Absolutely. You know, the Doge is
the chief magistrate of the Republic

of Venice, but it's not
a hereditary position.

It's not like a kingship.

It's worth remembering, they can't
meet the foreign ambassador on their

own, they have to be shepherded.

There is a very strict chain,
if you like, kept on the Doge.

It's a very unusual
and unstable position.

'The Venetian system the government
seems absurdly complex,

'as if designed to obscure
where the real power lay.'

But every aristocrat in this room
was also a merchant and so whether

making laws for fighting wars,

the Venetians' priority was to
protect and increase their wealth.

'Venice conquered territory as far
away as Cyprus and the Crimea and

'defended her trade routes -

'from the Black Sea to Gibraltar
and beyond.

The secret of her naval success was
hidden in a city within the city,

behind 4km of eight
metre-high walls -

the Arsenale.

This enormous shipyard is still
a navy base to this day.

By the beginning of
the 16th century,

they'd built a fleet of over
3,000 ships.

The English navy, under the first
Tudor king,

Henry VII, had just five.

This is where Venice becomes
a global superpower.

This is how
they protect their trade.

This is how they keep
dominion at sea.

The Venetians invented the world's
first production line here.

There were over 100 separate areas

to produce all the different
components needed to make a ship.

Expert craftsmen churned out
anchors, ropes, oars and masts,

all in standard sizes.

Once the hull of a ship was
watertight, they floated it around

the complex and added the parts
straight out of the factory.

This was industrial production
on a scale not seen anywhere else

in the world for another 500 years.

At its height, 16,000 people
lived and worked here

and the Arsenale area
took up one tenth of Venice.

And just absolutely extraordinary
to think how far ahead they were.

Three ships a day
are being turned out here.

I mean...

It's just mind-boggling.

The Venetians celebrate their
mastery of the sea every year on the

Feast of the Ascension,
Festa della Sensa.

It dates back to 1177, where
the Pope gave the Doge a ring,

a ring that was to symbolise the
wedding between Venice and the sea

and as part of the
Festa della Sensa,

they would go to the lagoon entrance
and throw that ring into the sea.

Now, lots of people get married
in Venice,

George and Amal Clooney
most recently in 2014,

but I bet none of them had the sort
of wedding ceremony that is intended

here at the Festa della Sensa,

because this is not
a marriage of equals.

The sea and the dominions that
Venice control had no option to say

yes or no. This was a marriage
in which the wife, the sea,

was to obey her husband, Venice.

This festival is now passing Italy's
modern naval military college.

And there they are, saluting.

Italy's modern naval power,

saluting the symbol of Venice's
ancient maritime supremacy.

The city's religious leader,
the Patriarch,

would bless the wedding ring and
give it to the Doge.

Today, the mayor of Venice
takes the Doge's place.

HE SPEAKS ITALIAN

CHEERING

HORNS BLARE

While Michael's enjoying
the Venetian wedding party,

he's sending me on a mystery tour
two miles across the lagoon.

We've come to this island here.

It has the appearance of a sort of
penal colony with these high barred

windows and...

I'm going to say not very
decorative structures on it.

But I guess all will be revealed
to me when we dock.

I'm not quite sure
where we are docking.

Hi!

Ciao! Ciao.

Welcome to the Island
of Black Death.

Right, we're off, OK.

Back, back, back.
I'm joking, I'm joking.

The Island of Black Death. Well,
listen, that explains everything.

Yeah, please.

Alexander, very nice to meet you.
Martino Rizzi.

Ciao, how do you do?

Goodness me.

All those ships bringing exotic
luxuries from the East

were also carrying rats and with
them exotic diseases,

like the plague.

Victims would suffer painful
swelling and bleeding.

Their bodies started decomposing
before they were even dead.

In one outbreak, over half the
population of the city

was wiped out.

The Venetians came up with
a radical solution.

From 1361 until 1528,

we registered 22 different
outbreaks. 22.

And that's why, after a while, they
decided to make the first isolation

hospital in history.

Created in 1423 by the Republic of
Venice.

And they chose this little island,
it's very small.

Anyone showing symptoms of the
plaque was immediately removed

from the city
and rowed out to this island.

Even today, this feels like a
desolate place.

Very few Venetians
set foot on the island.

You soon notice there aren't even
any birds singing.

'Doctor Rizzi and his team have been
excavating graves and restoring

'buildings here for over 15 years.'

There was obviously no cure for it
but did some people survive,

or was it...? Very, very few.

Believe me, we walk on mass graves.

WHISPERS: Oh, Lord.

During their work, the
archaeologists found over 1,000

crates of human bones under
one collapsed wall alone.

Please, take a look inside.

How effective was it
in controlling the plague?

Very.

Here, in the island,

the people arriving could get
two things that were very important.

The last rites.

Right, so there were priests here?

Yes. And the second thing was
basic food, basic assistance.

Right. Almost no medicines. Yeah.

God, it goes on and on.
Please, yes, on and on.

It's just... Hall after hall.

And by night, it's not the happiest
place to visit.

I can easily believe that.

How many people do you think
died here?

It's impossible to know.

Tens of thousands, minimum.

This was a hell on earth.
A hell is exactly it.

That's exactly it. This is the image
I have of this island.

From here, you can see
how big it is.

Really, you can get lost.

Look how big.

Oh, my Lord. Oh, my Lord!

It's just overwhelming
to think of the sheer number

of untold tragic stories that

must have worked out
their sorry ends here.

But tempting though it is to wallow
in the tragedy of it,

there's also something brilliant
about this.

Yes, it was vile to bring people
over here,

but it contained the plague
and it must have saved

further hundreds of thousands
of lives.

Half a century later,

Venice took the idea of isolation
one stage further.

Michael's exploring an island
four miles away,

by the entrance to the lagoon.

From 1468, all ships arriving in
Venice were required to stay here

for 40 days
before entering the city.

Our word quarantine comes from the
Venetian practice of making their

traders stay on this island
for 40 days.

"Quaranta," that's our quarantine.

The incoming goods were also
unloaded off the ships into this

massive warehouse
in the centre of the island.

Here, they were disinfected
with vinegar,

boiling water and smoking herbs.

This building was built and paid for
by the Venetian state,

because if Venice
couldn't keep its trade going,

if Venice couldn't ensure that
this artery continued to flow,

Venice itself was dead.

The Venetians conquered
the Black Death,

but they couldn't fight
the tide of history.

In the Elizabethan age,
new competition from English,

Dutch and Spanish traders,

piracy and wars with the Turks
all started to cut into the Venetian

merchants' bottom line.

But the Venetians still had
one thing left to sell.

The city itself.

Venice's wealth had paid for
the world's greatest architects,

painters and musicians.

For the super-rich, this was now
an essential place to see in the

aristocratic gap year
known as the Grand Tour.

Tony Perrottet has written about the
seedier side of the Grand Tour.

So, Tony, you look around and you
see that Venice is just a massive

tourist trap. They have cruise ships
the size of small market towns

arriving, but I suppose 250 years
ago with the Grand Tour,

it was similar even then.
Absolutely,

it was a great tourist destination
in the 18th century,

but people came for a different
reason.

It was the sin city of Europe.
Really?

So, sex, gambling, sensuality.

The city was devoted to
erotic pleasure.

There were beautiful casinos
all over the city.

The Florian here was once
one of the great sights for

the romantically inclined, because
women were allowed to be served,

which was quite unique
in Venice at this time.

And there was a brothel upstairs.

No! Here? Yeah.

They keep that quiet.
Now it's very glamorous.

Look at it with its posh
string quartet playing.

Very straight. Butter wouldn't melt.

It's a facade.

There's other places in Venice
that are even more

appealing these days.
We can go and have a look at one.

Excellent!

Tony is an expert on one of Venice's
most notorious playboys,

Giacomo Casanova.

Casanova was a writer, musician,
all-round intellectual,

and a notorious gambler.

But he's become best known for
his exploits in the bedroom.

I hope this isn't going to get me
into trouble at home.

And here we are, this is
one of the original casinos,

that Casanova would have visited,
for sure.

This is it. So, this is
an 18th century...?

Yeah.
..Venetian Casino.

This is exciting. Yeah, one of the
great gambling houses of Europe.

Wow, think how many fortunes were
made and lost in here through these

doors. Look at this.

A real sense of luxury and
decadence.

It would have been filled with
gambling tables here.

Beautiful. It's terribly elegant,
isn't it?

Everything was exquisite, beautiful
food going by, great wines.

Gorgeous women, of course.
I see, yes.

And certainly quite a lot of,

quite a lot of dalliance
going on in here as well.

Yes. Venice had around 100,000
people in the late 18th century,

of whom 12,000 were prostitutes,

which is 12% of the entire
population. Extraordinary.

Now the Venetian courtesans were
very famous, weren't they?

Oh, yeah. It was legendary, because
they were extremely well educated,

they could speak many managers,
play musical instruments.

The courtesans used always
extraordinary fashion tricks,

they would soak their hair in
urine,

which would give it a sort of
reddish golden glow.

They would put raw veal on their
cheeks to improve the complexion.

And they would dress fantastically
with these beautiful plunging

bodices and these quite amazing
platform shoes.

What size shoe are you?
Want going to try one on?

Yeah, absolutely.

I mean, if these fit,
I'll be walking out in these,

I should think.
They're more like a circus outfits.

They have something of the circus
about them.

There we go, I think you're fitting
into these.

These become me.

Oh, look, and on, there we go.

We've got a strap there,
maybe back here. Oh!

Very fetching. It looks suspiciously
like I've been wearing these before,

doesn't it, Tony?

It's almost too beautiful.

I can hardly tear my eyes away.

Doing a great job there.
You might have to give me...

Oh, no, I need no help at all.

There we go. Look at that. Now if
you could just imagine yourself

as a ravishing Venetian...

What do you mean, "imagine myself,"
thank you very much.

This is...

Wahey, whoa! Wahey, there we go.

There we go. I think that's...

..enough of this folie de grandeur.

I love my ankles as they are.

Casanova had over 100 casinos to
choose from in the city.

But he would have to be
on the guest list.

Hey, Xander, hey,
Alexander, let me in!

Ah, Tony, how are you?

So, as you can see
it was just like a speakeasy.

If there was a bang on the door,
you could come in and you could look

down and see who was there.
If it was someone, if it was the

police, someone you didn't want to
see, someone's husband,

there was a secret exit out the
back. So, you could see who was down

here and just get out of there if
you needed to avoid them.

Not today, thank you.
Not today.

18th-century Venice wasn't all
debauchery and decadence.

In 1755, Casanova's life of pleasure
caught up with him.

He was arrested and
with no reason given,

he was marched off to a room
high in the Doge's Palace,

the torture chamber of
the Three Inquisitors.

Like Casanova, I'm still not sure
what I've done to deserve this.

So, Casanova was led up here
into the torture chamber,

which is the most terrifying and
legendary place in the whole palace.

The three inquisitors were there
and this was their

favourite thing of the Venetian
Inquisition, "the strappado,"

also known as, "la corda."
Just, "the rope."

The strappado,
so how would that work?

That in effect, that's...
Very simple.

Yeah, you would have your arms
tied behind your back. Yes.

And then... Facing the inquisitors.

Someone would actually pull it up,
so you would be taken up fairly high

and then dropped to
just above the ground.

So, your arms would be like
wrenched up and it would often

dislocate your shoulders. I bet.
So, screams would echo

through the prison. And the other
prisoners were in cells up here.

I was just wondering, so you've got
barred windows there and there are

windows right by it. So, I would be
strung up that high, would I?

Yeah. So, I would be screaming
in their windows.

Casanova when he comes up, he's so
terrified he goes to the bathroom

every 15 minutes, he records.
He's so scared.

He still doesn't know
exactly what's going on.

Of course,
his main crime was hitting

on the Inquisitor's girlfriend.

I think that was a pretty serious
black mark against him.

This is the secret state,
police state reality

of what Venice can and will do.

And we're still in the
Doge's Palace, I mean,

this is what I can't
get my head around.

Venetian society by the 18th-century
was sort of rotting from the inside.

It was all falling to bits. And
there's all this sense of secrecy,

there's people observing you,
spies everywhere.

Casanova was locked up
in a squalid cell,

squeezed under the roof
just above us.

After 15 months he made
a daring breakout.

Accompanied by a fellow prisoner,
he dug his way out onto the roof.

He climbed back into the palace
through a dormer window.

He then snuck down through the maze
of rooms and corridors and walked

brazenly out by the front door.

Casanova and his accomplice were the
only two prisoners ever to escape

from the palace prison.

'The scanning team has combined
173 separate scans to build a

'three-dimensional digital model
of the Doge's Palace.

'Matt is going to take me on
a virtual reality tour.'

So, Xander, with the help of
our headsets here,

we are into Venice in a way that you
will never have seen it before. OK.

Oh, look at that.

Wow. Here we are in
St Mark's Square.

There is a kind of me-sized
St Mark's Tower,

just stood between
the two of us there.

There we go.

So, you're parading around like a
giant.

Shall we take another layer of zoom
and get inside? Oh, yes, let's.

Oh, wow!

I know this room only too well.

Yeah, so having seen this kind of
remove perspective

of doll's-house world,
we are now back in one-to-one.

Absolute real dimension.

We're in this terrifying
torture chamber,

but if you crouch down now and if
you just look through the floor

here, we're actually just hovering
inches above another room.

So, let's actually drift down now
through the floor level now

and check out the slightly more...
It's slightly weird, isn't it?

Whoa! We we're going up.

There we go. Down we go. OK.

Wow. Out of body experience,

disappearing down as the floor
comes crashing up to us.

And I think that's about perfect.

And up above there is that painting.

There it is. Looking on the one hand
angelic, but actually we get this

privileged view, we see through,
transparently,

into that hall of torture
directly above us.

The virtual tour reveals how the
torture chamber is connected to a

network of rooms and cells specially
created for the secret police,

the interrogators and their
secret archives.

From the early 1600s,

the Bridge of Sighs joined the
palace to an additional prison.

Its tiny windows gave captives
their last view

of the outside world.

'As Venice's power
in the world declined,

'the state's paranoia increased.

'Finally, Venice found herself
caught between

'Napoleon's conquering armies
and the rising Austrian Empire.

'In 1797, the last of the republic's
120 doges surrendered to the French.

'The Lion of St Mark was toppled
from its column.

'Venice lost her independence
forever.'

Thankfully, the wonders created by
a millennium of Venetian ingenuity

have survived.

We've combined over 400 scans to
complete our monumental 3D model.

It reveals the city's invisible
secrets in all their glory.

The Grand Canal.

The synagogues hidden in the ghetto.

The might of the Arsenale.

And the hidden network of power
and terror in the Doge's Palace.

Venice, La Serenissima,
preserved forever.

There's not a bit of Venice
that isn't beautiful.

It's not possible to be here and
not at least be cheered by the

combination of the sparkling
sunlight on the water,

the grandeur of the vistas.

Venice is just enormous fun.

You know, just everything
happening on water.

It's bonkers. It's absolutely
bonkers. But enormous fun.

I mean, our very sense of the
romantic and romanticism,

born not least
out of half the places

and buildings from this very town.

I think Venice is
absolutely perfect.

Cheers. Yeah, cheers. To Venice.
To Venice. Venezia. Venezia.

Next time, Florence.

I mean, my word.

A beautiful Renaissance city
forged on rivalry.

Oh, that was a kick to the face!

This was Florence bursting out.
