An adventure of discovery to try to understand the story of humanity.

I can't believe I've been allowed down here.

Ugh!

This is absolutely incredible.

Islands can offer escape, sanctuary, encourage resilience in the face of adversity, and allow civilizations to meet.

Today, the island of Malta.

♪♪ Its story is unique and brilliantly rich, so I'm very lucky to get to explore it.

♪♪ At only 17 miles across, Malta may be the world's 10th-smallest country, but this tiny island is a rich layer cake of history.

♪♪ Malta's strategic location, right at the very heart of the Mediterranean, means it's attracted friends and foes.

And it's been fought over by foreign powers for thousands of years.

So, from Stone Age travelers to Crusader knights to British royalty, all kinds of outsiders have left their mark here, meaning this is one of the most remarkable time capsules in the world.

With fabulous access to the island's treasures, I'm exploring what the story of Malta reveals about the world and us.

♪♪ The Maltese archipelago sits between Africa and Europe, and my first treasure exists thanks to that pivotal location.

♪♪ ♪♪ It's a 500-year-old wonder of construction, a huge, imposing city fortress, a reminder that crises can spur creativity.

♪♪ This is one of the most strategic spots in the whole of the island.

Control this vantage point and you control the Grand Harbour, and therefore, you control the island of Malta, and beyond that, hundreds of miles' worth of seaways right across the Mediterranean.

♪♪ This is Fort St. Angelo, the gateway to Malta.

♪♪ The lion's share of what you see today was built by the Order Of the Knights of the Hospital Of St. John.

Under their command, this fort witnessed one of the most vicious and game-changing conflicts in history.

♪♪ The story of the knights starts far from here, in Jerusalem, in the 11th century, when the Christian order was founded to defend the Holy Land and the pilgrims who traveled there.

For 200 years, they were in the Middle East, building a hospital in Jerusalem, and stayed until Muslim forces took over the region and they were kicked out.

They searched for a permanent base.

In 1530, the key power player of the day, the Holy Roman emperor, finally found the knights a new home -- this place.

At that point, a half-ruined castle, this could be an ideal H.Q.

But there were two conditions.

Every year, the knights had to supply the emperor with a single peregrine falcon, and they had to promise to wage incessant war against pirates and infidels.

The falcon was easily enough done.

As for pirates and infidels, that was a bigger ask.

The emperor had in mind the superpower of the day, the Ottoman Turks, steadily expanding their empire, with their eyes on Malta.

The knights had to weaponize their new base, so they expanded outwards, beyond the castle, constructing massive fortifications on the rocks all around.

Once secure, the knights, known as Hospitallers, practiced what they preached.

[ Choir singing ] ♪♪ ♪♪ Because the knights were monks, they were celibate; they took vows of poverty, chastity, and obedience; and they were obliged to do good works.

So they looked after the poor, the needy, orphans, and abandoned women, treating all patients, including Jews and Muslims, with practices partly inspired by their time in the East.

♪♪ In May 1565, the knights had to put aside their caring duties, mustering every ounce of their soldiering skills, because the Ottoman Turks were on the attack.

♪♪ Malta was besieged... and Fort St. Angelo was the heart of the knights' resistance.

♪♪ On the 19th of May 1565, almost 300 Ottoman ships sailed into this harbor.

The horizon was white with their sails.

And then, as the battle began, eyewitnesses described the sea running red with blood.

♪♪ It was a struggle between two superpowers for control of the strategic island.

We're told that the Ottomans had over 40,000 men against just 700 knights and 8,000 soldiers.

The defenders of Malta were outnumbered four to one.

♪♪ What followed was one of the bloodiest and most ferociously contested sieges in history.

♪♪ Time and time again, the knights used incendiary devices -- basically, dirty, flaming bombs -- that they catapulted out at the enemy Ottoman ships.

At one point, when the Turks had the upper hand, they took four headless bodies of the knights, gashed crosses into their chests, lashed their bodies to crucifixes, and sent them back to Fort St. Angelo as a terrible message.

In retaliation, all of the Turkish prisoners were decapitated, and their heads were used as cannonballs.

♪♪ We're told that even the Maltese women and children got involved, pouring flaming oil from the ramparts.

There was desperation and horror and suffering on both sides, Ottoman Turks and knights alike.

♪♪ After four months, Fort St. Angelo still stood firm.

The Ottoman Turks retreated.

They'd lost 30,000 men; Malta, one third of its population.

But from the flames of destruction, something wonderful arose.

♪♪ Surviving the crisis of the Ottoman attack, the knights were galvanized to build a splendid new city -- Valletta.

Valletta, named after the leader of the order, Jean Parisot de la Valette, was a bold, new dream metropolis.

And with its giant secure walls, the whole city became a fortress, a kind of child of Fort St. Angelo, keeping the Maltese and its knights safe.

After the horrors of the siege, the Maltese resolved never to be vulnerable again.

So they constructed a secret subterranean world under the streets.

And I've been tipped off there is access down there, somewhere a bit special.

♪♪ The knights and the people of Malta realized that they had a real ally in the form of the rock that the island itself is made of.

So, it's soft enough to carve through, but strong enough to support huge weight.

[ Water splashing ] It's perfect anti-siege engineering.

Now the fortified city could be more self-sufficient.

♪♪ ♪♪ Down here, there are sophisticated sanitation systems and vaults for storing food and huge systems like this that would keep the population of Malta fed and watered for months.

This subterranean innovation helped keep the Maltese people safe from disease and starvation for centuries, fired by the suffering of the Great Siege of Malta, centered on Fort St. Angelo.

Fort St. Angelo is a wonder for me because it reminds us that necessity really is the mother of invention and that we should understand history from all vantage points.

♪♪ Through the story of the world, islands have been engines of civilization, stopping-off points for travelers, where people meet, where goods and ideas are exchanged.

These are the clay jars in which wine, olive oil, and possibly other consumables, such as honey... -Ah.

-How many amphorae in total?

-There are over 100 visible.

But we know that there are many more buried in the sediments.

♪♪ So, this is a time where we often don't have much archaeological evidence, so it's a real kind of mysterious time in the story of mankind.

But this is where it was all happening then.

-It's the center of a trading network that existed in this part of the Mediterranean.

-The Phoenicians, great influencers, originally from the Middle East, moved goods and innovations between continents, from the world's first written alphabet to cargo like this.

-When we recover objects from underwater sites, sometimes we're the first people to touch these objects in 2,000 years.

And have you analyzed this?

Do you know what it was carrying inside?

-In this particular case, we're leaning towards it transporting wine, because the inside of the amphora is lined with pitch.

-The ancients did not like their wine tainted by the taste of the terra-cotta pot, did they?

-Absolutely not.

But it's not wine as we know it today.

It is concentrated.

This concentrate would go into some form of mixing bowl, add water, and then consumed.

-I'm convinced that this is a locally made pot with locally made wine.

This was a ship that was leaving the Maltese Islands, on its way to trade elsewhere.

I mean, it's tragic in some ways, isn't it?

Because it didn't get very far from the coast.

-It's tragic because somebody lost a fortune.

I'm absolutely certain that, you know, people lost their lives, as well.

♪♪ My next wonder is a story of exile and achievement... because, five centuries ago, a notorious artist on the run fled here and produced a work that would mark a turning point in the history of art.

Caravaggio was an Italian painter who was born in Milan in the 16th century.

He was really a wild genius who created incredible works.

He used real people as models, even for biblical figures, ushering in a naturalistic style, kick-starting modern painting.

♪♪ But for me, this particular painting is a real wonder of Malta.

And the story of how it came to be created here on this island is one packed with intrigue, corruption, and murder.

♪♪ This, Caravaggio's masterpiece, is particularly amazing when you know its backstory.

♪♪ There was a dark side to Michelangelo Merisi da Caravaggio.

He was tortured and talented and dangerous.

In his motherland, Italy, he killed a well-connected Roman in a duel.

With a price on his head, he fled south to Malta.

♪♪ The knights immediately latched on to this celebrity and admitted Caravaggio as a novice to the Order Of St. John.

From brawler to murderer to Christian knight, it was quite the transformation.

[ Bells toll ] Caravaggio was now apparently on the side of the angels, and the knights capitalized on his presence.

In 1608, they commissioned him to paint a grand altarpiece for this, their magnificent new cathedral.

[ Choir singing ] ♪♪ Ah, this is absolutely incredible.

Oh.

A showcase for their Christian order.

♪♪ ♪♪ This was a fulcrum of the knights' influence, and trendy, turbulent, talk-of-the-town Caravaggio was asked to paint a statement piece, which is still here.

At the time, Caravaggio was still on the run, still wanted for murder, so it's extraordinary he should be asked to make a painting for this holy place.

I'm about to see it in the flesh for the first time.

A servant girl waits for the severed head with a golden platter.

This doesn't just feel like an illustration of a Bible story.

It feels very personal, it feels really intimate.

It's almost like photojournalism.

Caravaggio would have seen men beheaded in the world around him, and you wonder if this painting is talking about that or whether he's actually prefiguring his own fate.

♪♪ This is the only painting that Caravaggio signed, and where he chose to put his signature was in the blood that's pooling out of John the Baptist's neck.

That has to say something about his mental state, about how dark and desperate he felt while he was here.

♪♪ Shortly after completing this masterpiece, the fugitive was in trouble yet again.

Another brawl, and this time, a high-ranking knight was severely wounded.

I mean, there's no way you could get out of here by yourself, so he must've bribed or maybe blackmailed somebody.

What a stunt.

Caravaggio vanished from his rock-cut cell... and from the island of Malta.

They laid his robes to symbolize the man in front of this painting, and they found him guilty.

If Caravaggio had been here in person, he'd have been beheaded.

As it was, they stripped him of his promised knighthood.

Within two years, he was found dead in mysterious circumstances -- quite possibly the knights' last revenge.

And for the Allies, the next obvious place to attack was Sicily.

From Sicily, the Allies could exert pressure on Fascist Italy and northward through Europe.

But they knew that the Germans would realize that.

They had somehow to persuade them otherwise.

Sicily was such an obvious target that the Brits attempted all kinds of ingenious plans to divert the Germans' attention elsewhere.

[ Water bubbling ] The most infamous aimed to throw the focus to Sardinia.

A corpse -- a real corpse -- was dressed as a Royal Marine.

And the body was planted with fake papers identifying the man as a William Martin, an officer who'd been lost at sea in a fictitious air crash near Gibraltar.

Chained to the body was a briefcase containing more fake documents, hinting that after Tunisia, the Allies were going to invade Sardinia.

British intelligence rigged it so the body was washed up on a Spanish beach, where it was handed over to the German authorities.

It was a great idea, and it's a great story.

But, sadly, this ruse had little direct effect, other than to raise the alarm... and the stakes.

With the enemy's attention focused on Sicily more than ever, the Allies were under extreme pressure as they planned their invasion.

So they sent troops and officers from Britain, the U.S., and Canada, a massive international effort, all to be commanded from Malta.

The whole thing would be run from this room.

The Allied supreme commander, General Dwight Eisenhower, arrived to direct the operation, and he sat right here.

What followed, as the Allies prepared to take Sicily, was one of the largest amphibious operations ever attempted, with more troops than D-Day.

Operation Husky was launched in July 1943.

It all began just before dawn on the 10th.

Over the next three days, over 3,000 boats transporting 150,000 ground troops, flanked by 4,000 aircraft in the skies, made their way toward Sicily.

They were met by over 260,000 enemy Axis troops.

38 days of brutal, bitter fighting followed.

They came from what's now Sicily and North Africa in search of new opportunities.

They must've been curious or desperate, I mean, certainly, with an incredible spirit of adventure, to brave these waters in a small boat, not knowing what lay ahead of them.

I'm not surprised they tell stories like this, because some of these stones are over 5 meters long and they weigh over 50 tons.

There's no evidence of slavery from this culture.

So you didn't know if there was going to be a disease or animal attack or crop failure, so death was always just around the corner.

So, to take time out to make this tells me that what happened down here really, really mattered to the people of the island.
