NARRATOR: Tonight on The Curse of Oak Island...

I found something.

-MARTY: This is special.

How old does this go back?

There are examples back in medieval times.

ALEX: We are looking for connections to Oak Island here in Italy.

-PETER: Oh, wow. -DOUG: Templars built this castle?

RICK: Those are symbols we have on Oak Island.

DOUG: So this is connected with Nolan's Cross.

CORJAN: This would have been an ideal hideout.

-JACQUO: There we are, guys. -RICK: Wow. Look at that.

CORJAN: They took their treasure here

on their way up to Oak Island.

Oh, wow. That is a lot.

NARRATOR: There is an island in the North Atlantic

where people have been looking for an incredible treasure

for more than 200 years.

So far, they have found a stone slab

with strange symbols carved into it,

man-made workings that date to medieval times,

and a lead cross whose origin

may be connected to the Knights Templar.

To date, six men have died

trying to solve the mystery.

And according to legend, one more

will have to die before the treasure can be found.

MARTY: All right, so, the objective here is

find the treasure, to find where

the metals in the water are coming from.

-Correct? Okay. -Yeah.

NARRATOR: Another chilly fall season

has descended upon Oak Island.

But for brothers Rick and Marty Lagina and their team,

hope remains high that they still have time this year

to make a discovery in the Money Pit area

that could finally solve

a 229-year-old treasure mystery.

We have locations that you and Fred have picked?

-Correct? -Yeah. Fred and I have talked it over.

-Okay. -Yeah.

And we do know as well that this is where

we had some of the highest metal results.

NARRATOR: Just two weeks ago, the team believed

that they were close to a major breakthrough

as representatives from Dumas Contracting Limited

began a lateral probe-drilling operation

to explore a seven-foot-high, dilapidated tunnel

that was discovered some 106 feet deep,

just below the Garden Shaft.

A tunnel that runs due west towards an area dubbed

the "Baby Blob," where geoscientist Dr. Ian Spooner

and his colleague, Dr. Fred Michel,

detected high trace evidence of gold and silver

during previous groundwater tests.

NARRATOR: However, shortly after

the probe-drilling operation began...

...the Garden Shaft suddenly flooded with salt water,

forcing the team to abandon the operation,

and speculate that they had encountered

one of the legendary flood tunnels

which have thwarted treasure hunters

for more than two centuries.

So, we've got locations based on the work

-from Dr. Spooner and Dr. Michel. -Okay.

NARRATOR: Now, because the team can no longer horizontally drill

at the bottom of the Garden Shaft

to look for the precious metals that have been detected

in the Baby Blob, Drs. Spooner and Michel

have conducted new groundwater tests

and identified potential treasure targets

in the area between depths of 80 and 120 feet,

which the team will investigate

by core-drilling from the surface.

We're standing where we should be

on top of the tunnel, but we don't have any

information connecting the tunnel through here.

MARTY: You know, Ian Spooner

and Fred Michel,

they don't take positions lightly,

and they are still of the opinion

that there is a substantial mass of precious metal

very near the Baby Blob.

We're gonna go

where the science tells us to go.

We need to find the source of those metals.

I really feel like the data suggests

-there is a big clump of metal here. -IAN: Here.

-Right. -We have some prep work to do here.

-Yep. -SCOTT: And everything will be ready to go.

All right. Let's make it happen.

NARRATOR: While the search for treasure continues on Oak Island...

...approximately 3,500 miles to the east,

in Morimondo, Italy...

RICK: Here we are. There's Emiliano.

-DOUG: I see some familiar faces. -RICK: Yep.

-Hey, guys. -RICK: Emiliano.

How are you? Good to see you again.

Professor Gaspani. Good to see you.

Hello, sir. Good to see you again.

NARRATOR: ...Rick Lagina, his nephews Alex Lagina

and Peter Fornetti, along with Doug Crowell,

are beginning a research trip to investigate

the possible origins of

the 229-year-old mystery.

EMILIANO: Welcome to Morimondo.

This is the Cistercian Abbey

of this little town.

NARRATOR: Today, researcher Emiliano Sacchetti

and archeoastronomer Professor Adriano Gaspani

have arranged for the team to visit Morimondo Abbey,

the site of a monastery that was established

by Cistercian monks back in the 12th century.

We decided to start from here because Cistercians

were among the greatest builders of the Middle Ages.

And according to Professor Gaspani's theory,

whoever built the Nolan's Cross

was close to some monastic circles.

So, they knew the sacred geometry.

-Oh. -Oh, wow.

NARRATOR: According to the research

of Professor Gaspani,

three megalithic stone formations

that have been discovered on the surface of Oak Island,

known as Nolan's Cross,

the five pyramid-shaped stone piles on Lot 15,

and the stone triangle that once stood on the south shore

were constructed based on alignments with stars

in the night sky back in the 13th century

by members of the Knights Templar,

the Christian military order that some believe

smuggled priceless religious treasures from Europe

to Oak Island as much as eight centuries ago.

(speaking Italian)

I am convinced that Nolan's Cross

may have been built by

a Knight Templar, or by a Cistercian monk.

ALEX: Mm-hmm.

So we are looking for connections to Oak Island.

We're looking for the possibility of a connection

to the Knights Templar, and we might see that here?

Right.

NARRATOR: The Order of Cistercians was founded

in 1098 and constructed numerous abbeys across Europe,

including the Morimondo Abbey in the late 12th century.

Known for advancements in the sciences,

including architecture, engineering and astronomy,

the Cistercians recorded their knowledge in decorated texts

known as illuminated manuscripts.

The order was also closely connected

to the Knights Templar,

whom Professor Gaspani believes

may have used abbeys such as this one in Morimondo

to not only share secretive knowledge,

but also smuggle their sacred treasures across Europe

before transporting them to North America.

Before we get into the church,

I would like to show you something.

RICK: The breadth of knowledge that Professor Gaspani has

is integral to this process.

And he said there was indeed a very

profound connection between Templars and Cistercian monks.

And the hope is there'll be a connection

between that knowledge and perhaps

a voyage to the New World.

And of course, to the island in particular.

EMILIANO: So, on top of the facade,

you can see some ceramic vessels?

-Oh, yes. -Yeah.

EMILIANO: And if you pay attention, on the left side,

there is a group of five.

Two have

very specific symbolism.

I see it.

-I see a couple of four-dot crosses. -EMILIANO: Yeah.

DOUG: We have the four-dot cross carved

on the H+O Stone on Oak Island.

Oh. (laughs)

EMILIANO: There it is.

DOUG: I see a four-dot cross.

We have the four-dot cross carved on a stone

on Oak Island along with a circle with a dot in the center.

NARRATOR: At a 12th century Cistercian abbey in Morimondo, Italy,

Rick Lagina and members of the team

have just found a symbol known to be

connected to the Knights Templar

that has also been found on Oak Island.

ALEX: The H+O stone, we've only seen

the photographs, but it's carved deeply.

Right.

NARRATOR: Discovered on the northern shore

of Oak Island back in the 1920s,

the so-called H+O Stone,

which featured a cross surrounded by four dots,

was part of a larger boulder

that had been detonated by searchers

who mistakenly believed

that it marked the location of buried treasure.

Is it possible that the team has found

an important clue outside of Morimondo Abbey

that offers more evidence connecting the Knights Templar

to the Oak Island mystery?

So what about getting into the church and taking a look?

-ALEX: Yep. -Yeah, that'd be great. -Love to. Yep.

RICK: The H+O stone, it's an integral part of the story.

And if it was meaningful to the people

who were here, i.e., the Cistercians

and perhaps the Templars...

me, personally, I think it's too ubiquitous a symbol for it

and too iconic to Oak Island for us to ignore it.

-Wow. -Oh, wow.

ALEX: Look at this. I did not expect this.

-PETER: Yeah. -ALEX: Wow. Yeah, it's...

It's stunning.

EMILIANO: So, this is it. 60 meters by 13.

So, very long and narrow.

Eight massive pillars on each side.

But, let-let's just spread out

and take a look.

ALEX: It's interesting that we see this

four-dot cross on the H+O Stone, which we

seem to see at a lot of Templar sites,

which is very interesting.

The church there has several

really significant orientations

and markings, and I'm excited to find out more.

You see the Templar cross?

DOUG: Oh, yeah.

ALEX: I'm hopeful that we will

be able to learn something,

or at least see some symbols here

that could be really important

to help us figure out

what's going on on Oak Island.

Okay. I think it's time to go

-to the scriptorium. -ALEX: Okay.

I'm really looking forward to show it to you guys.

-Okay. -You lead the way.

The scriptorium was a place where the monks

used to study,

copy, illuminate

the manuscript that were recording

the knowledge of the times.

So, this is the-the scriptorium,

and here in this place

there were at least ten monks

working, copying manuscript, studying them.

And, as you can see,

it's beautifully decorated.

These paintings are actually

made by Cistercian monks.

It's not a later addition.

And we're talking around the mid-13th century.

ALEX: Wow.

Right over your shoulder there...

-EMILIANO: Y-You mean this one? -ALEX: Yep.

We saw that in the Templar prison in Domme.

We did.

-What it reminds you? -Well, the tree of life.

Yeah?

NARRATOR: A painted depiction

of the tree of life?

The sacred religious symbol

believed by many to represent a pathway to God?

JERRY: I think it's possible

that this might have been inspired

by the Kabbalistic tree of life.

NARRATOR: In 2017, Rick,

Alex, and Peter visited

a 14th-century prison in Domme, France,

where members of the Templar order

had been incarcerated in 1307

by King Philip IV on charges of heresy.

However, some believe that

the true reason for the Templar persecution

was for the Catholic Church

to confiscate the religious treasures

that they possessed,

which may have included the Ark of the Covenant.

Much of the Templar treasure has never been found.

NARRATOR: But, curiously,

Nolan's Cross on Oak Island,

which Professor Gaspani believes was created

by Templar Knights around 1200 AD,

has also been thought by some

to represent the tree of life.

And on the opposite side of the pillar,

there is another four-dot cross.

What we learned last year is that this cross

marks a special place.

The scriptorium, for a monk,

-it was a special place. -ALEX: Mm-hmm.

RICK: I wonder if the work that was done here

was meant to be so secret and so...

precious that

only few were allowed

the actual information.

Yeah.

EMILIANO: The Templars, they were

bringing back

the knowledge from the Holy Land

and put into practice

what they have learned through the help of the Cistercians.

The only reason why I ask that question,

Emiliano, is because, I mean,

when I look at the cross there,

I see oak leaves.

If you're bringing information back from foreign lands,

part of that information is gonna be knowledge

of, um, exotic plants.

DOUG: Are you envisioning

a 13th-century Cistercian scribe

copying information about activities on Oak Island?

Yeah, I certainly believe that

what was done on Oak Island

would be preserved within Templar hierarchy.

ALEX: Yeah. I think

if there was somebody with knowledge of the New World,

this is a plausible way

for that information to be disseminated.

But we're still looking for the proof of that.

As this trip ensues, we may find something

that is even more definitive.

We would certainly love to-to go there

and learn more of what we learned today.

RICK: Grazie. Grazie mille.

NARRATOR: The following day, on Oak Island,

as preparations continue

for the new core-drilling operation

near the Baby Blob,

in the northern region of Lot 5,

located on the western side of the island...

LAIRD: I think it's gonna be really important to

-carefully excavate in here. -Yeah.

So, it means that the edge of the feature

goes at least over here.

NARRATOR: ...archaeologists Laird Niven,

Helen Sheldon,

and Moya MacDonald

continue investigating two mysterious stone foundations

that they believe were both purposely buried

more than two centuries ago.

In the foundation nearest to the shore,

the team has not only uncovered a concrete-like substance

and blue clay,

which have also been found

deep underground in the Money Pit area,

but also a 14th-century lead disc,

which may be related to the possible Templar cross

that was uncovered at Smith's Cove

back in 2017.

While in the feature located several yards to the south,

an iron spike was recently unearthed

that archaeometallurgist Emma Culligan has found

to potentially date back more than 800 years.

MOYA: What else shall I find? (sighs)

NARRATOR: Now, the team is looking for additional clues

at both sites

in the hopes of determining

when they originated

and just who created them.

Hmm.

Hmm...

Hey, Laird, Helen.

-What's up? -I found something interesting

over by feature one.

-Near the stairs. -LAIRD: Oh, yeah.

-It's a button. -MOYA: Yeah.

I thought the pattern looked

kind of interesting.

-LAIRD: The pattern's strange, eh? -MOYA: Mm-hmm.

LAIRD: It's not a pattern I've seen before.

HELEN: Wow.

LAIRD: We don't find a lot of white metal buttons.

But it's a strange pattern.

It's not a pattern I've seen before.

NARRATOR: On Lot 5, located on the western side

of Oak Island, archaeologist Moya MacDonald

has just made a curious discovery

while investigating the stone foundation near the shoreline.

Yeah. It's a, it's an odd pattern.

I've never seen it before.

It's almost like an asymmetrical spiderweb.

And you can see, on the reverse, where the shank was attached.

So, it's definitely a button.

-LAIRD: It sure looks old. -HELEN: It does.

-MOYA: Yeah. -Where was that?

It was in the northeast corner.

LAIRD: The artifacts that are coming out are really surprising to me,

and the building is completely unusual.

This may have been an industrial structure,

something other than a house.

But the fact that it's on Oak Island

adds to the mystery around it,

and, hopefully, the button can tell us

who was doing what and when.

LAIRD: It's really fragile for a button.

Yeah, I think we'll get that to Emma.

-Have her take a look at it. -MOYA: Yeah.

-Let's find out what sort of metal it actually is. Yeah. -Yeah.

It's an oldy. Good job.

NARRATOR: While the archaeologists

continue searching for clues on Lot 5,

some 3,500 miles to the east

in Bianzano, Italy...

-Morning, guys. -Morning

-Morning. -Ciao.

-Buongiorno. -Buongiorno.

Welcome to the Bianzano Castle.

NARRATOR: Rick Lagina and members

of the team are meeting once again

with archaeoastronomer

Professor Adriano Gaspani, his interpreter

Marzia Sebastiani,

and researcher Emiliano Sacchetti

at Bianzano Castle.

As you will see, there are some very close links

to the Knights Templar here in this castle.

Uh, there's also a close link to Nolan's Cross.

-Huh. Oh. -Oh.

NARRATOR: Dating back to the 13th century,

Bianzano Castle is believed by many religious scholars

to have once served as the Italian headquarters

for the order of the Knights Templar.

It is also believed by some

to have been one of the places

where the Templars may have safeguarded their treasures

as they worked to transport them

across Europe and, finally, to North America.

-Mm. -And the Templars built this castle?

Mm-hmm.

Hmm.

So, this is a structure built about the same time

as Nolan's Cross?

MARZIA: Nolan's Cross has a similar alignment

to the Cygnus constellation.

And, in this case as well,

the external walls have

a configuration, which is perfectly aligned

with the rise and the set

of the Cygnus constellation.

-I see. -MARZIA: And we have

the external walls pointing in the direction

of the Arcturus star,

which is the case with Nolan's Cross as well.

So, basically, we have the same configuration

that you have with Nolan's Cross.

It's the same stars that are being used as a reference.

NARRATOR: One of the key reasons that Professor Gaspani

chose to show this site to Rick and the team

is that, according to his research,

the castle was constructed based on alignments

with specific stars in the constellation

known as Cygnus, just like the design

for Nolan's Cross on Oak Island.

-That's what we struggle with. -ALEX: Yes.

As Gaspani said, uh, Templars were here,

and we can infer that,

also, from the symbolism that is inside the castle.

And then, once we're in, we will take a look at it.

-RICK: Great. -DOUG: Absolutely. Lead the way.

RICK: Three things align, right?

The date of Bianzano Castle construction

and Nolan's Cross construction

and also, that, that timeline aligns perfectly

with the-the rise of what we'll call Templarism.

If there was a reason to safeguard some treasure,

a case is being built that, partly through these alignments,

that, perhaps, something was done, uh, in North America.

So, this is the main entrance, and, as you can see,

it's full of different symbols.

-ALEX: Yeah. -RICK: Look at this.

EMILIANO: This symbolism refers,

in some parts, to the Templars.

DOUG: I actually see something

in that fresco that I recognize from Nova Scotia, I think.

-EMILIANO: What is it? -Right here.

-DOUG: See this eight-pointed star here? -Yeah. Yeah.

ALEX: Is there a significance

to that symbol, that shape?

That's like the Bedford Barren petroglyph.

Yes.

NARRATOR: In 2014,

Rick, Marty and Craig Tester

saw a mysterious eight-pointed star

carved into a rock in the Bedford Barrens,

located some 40 miles northeast of Oak Island.

The symbol holds spiritual significance

to the indigenous Mi'kmaw people of Nova Scotia

and it is believed by some

that the Mi'kmaw adopted it from the Templar order

after the two cultures made contact

back in the 14th century.

DOUG: So, we find it here in Northern Italy

and we find it in Nova Scotia?

RICK: That, maybe, was Old-World information

that had come to Nova Scotia.

NARRATOR: Is it possible that Doug Crowell

has found additional evidence at Bianzano Castle

that supports the theory

that members of the Knights Templar

brought their symbology to North America?

If so, could it have been connected to a secret mission

to hide their sacred treasures on Oak Island?

RICK: Well, when you start to look, it's everywhere.

-PETER: Yeah. -EMILIANO: Yeah.

DOUG: It does. Look, it just repeats everywhere.

EMILIANO: But the best is yet to come,

because Professor Gaspani has something he wants to show you.

-Look, why don't we take a seat? -DOUG: Sounds great.

NARRATOR: In Bianzano, Italy,

Rick Lagina and other members of the Oak Island team

are meeting with researcher Emiliano Sacchetti

and Professor Adriano Gaspani

at a 13th-century fortress that once served

as a headquarters for the Knights Templar.

This might be very revealing.

So, I look forward

to what Professor Gaspani has to show us.

EMILIANO: I shared with Professor Gaspani

the Cremona Document.

I asked him to think about the devices

described in the Cremona Document,

with a specific focus on the Abetor.

NARRATOR: In 2016,

Rick's friend, the late author and researcher Zena Halpern,

gave him and Doug Crowell a copy of the "Cremona Document,"

which had reportedly been discovered in a medieval church

in the town of Cremona, Italy, back in the 1970s.

Believed to have been coauthored by a 12th-century Templar knight

named Ralph de Sudeley,

the Cremona Document contained reported first-hand testimony

that the Templars did, in fact,

recover priceless religious treasures

beneath the Temple of King Solomon in Jerusalem.

Also described in the document was a device

believed to be known as an Abetor, which was designed

to track the positions of stars in the night sky

for the purpose of not only constructing buildings

but also for navigation on the high seas.

So, Professor Gaspani did his homeworks... (chuckles)

...and he decided to build his own Abetor.

Oh, really?

Wow.

DOUG: Wow. Nice work.

Beautiful.

MARZIA: So, with such a tool,

you can cross the Atlantic and stick,

uh, to the prescribed, uh, route.

RICK: We have found, on the island,

constructs from the period of 1200.

So, you would need a device such as this

in order to make certain

that you were secure in the knowledge

that you could sail back and forth.

DOUG: A navigational device

may have brought them across the Atlantic,

and utilizing the science

and the technology they had with them--

say, this device-- to build a construct

-on Oak Island... -Mm-hmm.

...then something like this could have accomplished that.

It al-- it almost certainly could have.

NARRATOR: Could Rick Lagina and members of the team actually

be looking at a type of device

that not only helped in the transport

of a vast treasure from Europe to Oak Island,

but also in the construction of Nolan's Cross?

I believe it has something to do with solving the mystery.

I can only say, "Thank you," prego.

We thank you greatly for your insight

and perspective again, in our search for truth.

DOUG: We have a flight to catch.

We're following this trail from east to west and our next stop

is, uh, in the Netherlands to meet with Corjan Mol.

Thank you for your time.

Thank you.

NARRATOR: The following morning on Oak Island...

TERRY: Very, very interesting hole up ahead of us, Charles.

-CHARLES: Yep. -Avanti-1.

CHARLES: Avanti-1.

Zero to eight, just as expected.

And that's gonna be eight to eight-- uh, 18.

NARRATOR: ...while Terry Matheson and Charles Barkhouse

supervise the new core-drilling operation

that has just begun near the Baby Blob...

-Let's slice and dice. -Okay.

NARRATOR: ...where they hope to locate the source of gold and silver

that has been detected some 120 feet below ground...

TERRY: Onward and downward.

-LAIRD: Hey, Jack. -JACK: Hey, Laird. Hey, Emma.

-MARTY: Science team. -NARRATOR: ...in the Oak Island laboratory,

Marty Lagina and Jack Begley join

archaeologist Laird Niven

and archaeometallurgist Emma Culligan.

My understanding is that this is something special,

-that you're gonna tell us about. -It is.

NARRATOR: They are eager to hear the analysis

of the ornate metal button that was found

in the large stone foundation on Lot 5 just one day ago.

So, I did a couple of map scans.

And so, this layer right here is highlighted in yellow,

which is the lead.

And then, the base metal is the tin content.

NARRATOR: Earlier this morning,

Emma scanned the button using the SkyScan 1273 CT scanner,

a device which emits X-ray radiation

to produce a three-dimensional image of its finer details.

She also examined it

using the X-ray fluorescence spectrometer, or XRF,

which uses gamma rays to determine the elements

that make up the object's composition.

Now we understand it to be

-a lead-coated tin button. -MARTY: Hmm.

Very few made of lead.

EMMA: Which makes it...

-Unique. -Yeah. (laughs softly)

LAIRD: It's a cast button,

so it's been cast in place.

It's a sunburst design.

MARTY: What about status?

Who would wear such a thing?

-Well, I mean, it-it's decorated. -Mm-hmm.

LAIRD: That elevates the status of a button...

-Right. -...right away.

But how-how old does this style go back?

LAIRD: The only equivalents

I can find to it...

...date from, like, 1600 to 1700.

And that's the latest.

-(laughs): No way. -Mm-hmm.

MARTY: Really? What's the earliest?

LAIRD: The earliest,

there are examples back in medieval times.

MARTY: Well, how about that?

LAIRD: It's a design that dates from medieval

into the 1700s.

JACK: You-you said some of these buttons

go back to medieval times?

1300s.

-Well, how about that, Laird? -Yeah.

NARRATOR: In the Oak Island laboratory,

archaeologist Laird Niven

and archaeometallurgist Emma Culligan have just informed

Marty Lagina and Jack Begley

that a button featuring a star design,

which was discovered one day ago in the stone foundation

near the shoreline of Lot 5,

could date back more than four centuries prior

to the discovery of the Money Pit.

Isn't this sort of a game changer for that, for that site?

-That's, that's what I feel. -Wow.

Well, if this does go back to medieval periods,

the guys are in Europe right now, investigating

Professor Gaspani's work on Nolan's Cross.

And he seems to think that that dated back to the 1200s.

So this might be more data

showing us that people were here.

Lot 5 is still a mystery.

And it seems like things

don't fit real well for one period of occupation.

I would like to get to the very bottom

of that structure. I want to know

when that thing was first constructed.

Jack's right. There are other dates

-that have to be verified, that go into the 1200s. -Mm-hmm.

There's still a lot of excavation to do, so...

Okay. Excellent find.

-Go find some more. -Yes.

-JACK: Great job. See you Laird. -MARTY: Yeah. See you guys. Thank you.

NARRATOR: While the search for treasures and clues

continues on Oak Island...

...some 3,200 miles to the east,

just outside the city of Maastricht

near the border between Belgium and the Netherlands...

Behind those trees, there is the river, um...

They call it the River Meuse in French.

...Rick Lagina and members of the team

are meeting with cultural historian Jacquo Silvertant

and author Corjan Mol,

who, along with his research partner Chris Morford,

recently published The Jerusalem Files--

a book describing how members of the Knights Templar

may have transported their sacred treasures,

including the Golden Menorah from King Solomon's Temple,

to Oak Island more than 700 years ago.

At the end of the 12th century, people started to dig

these quarries underground.

Vast labyrinths.

The people who-who made these quarries,

they might have had connections with the Templar order.

Wow.

NARRATOR: Corjan has arranged

for the team to explore

the 12th-century Caestert stone quarry.

It is one of the locations where he believes

the Templar order may have hidden their valuables

as they made their way across Europe

before ultimately transporting them to Oak Island.

This would've been an ideal hideout if you were on the run.

Just 15 meter, literally under our feet,

we have what we believe are, uh,

drawings by the Knights Templar

with a lot of symbols

that you are going to recognize from Oak Island.

-BOTH: Great. -That's awesome.

I think I'm gonna go to the archives.

-So, have fun, guys. -ALEX: Okay. -PETER: Yeah.

-This way. -ALEX: Okay. -Thank you. See you, gentlemen.

NARRATOR: Excavated beneath Sint Pietersberg Hill

between the 12th and 16th centuries,

the Caestert stone quarry

was used to mine limestone for the construction

of Catholic churches and abbeys throughout the region.

CORJAN: Uh, we do have an entrance or call it a hole.

So, go all the way down.

ALEX: Okay. That should be no problem.

-Can I have you take that, buddy? -Wow.

NARRATOR: Today, the quarry consists

of several thousand hand-carved tunnels,

totaling 15 miles of underground passageways

between the Netherlands and Belgium.

CORJAN: Okay. This way.

ALEX: Wow.

Wow. Look at that.

-Looks like the inside of a pyramid, doesn't it? -ALEX: Yeah.

RICK: Looks... It almost looks otherworldly.

-Doesn't it? -ALEX: Yeah.

JACQUO: And we're going down now here, uh...

-It's a bit steep. -Okay.

There we are, guys.

CORJAN: And then I would invite you to look up.

ALEX: Oh, wow.

That's extensive.

We have a four-dot cross there.

-In the corner. -ALEX: Oh, yeah.

CORJAN: Which we've seen in Italy, in Portugal.

Here now and, of course, on Oak Island.

Look, you can't deny where we have found it,

from place to place to place

that's associated almost irrefutably with Templars.

If we walk up here, there's some

very interesting stuff on the side of the wall.

-So... -JACQUO: Follow me.

RICK: When you know of a safe place,

you're gonna utilize it.

Not only to keep themselves safe,

but more importantly, to keep their beliefs safe.

And then you see represented high in this cave system

some of the important representations

of those beliefs.

Oh. Look at that.

I-I became almost childlike in that moment.

I-I think it, it's impactful.

Here we are.

ALEX: Oh, wow.

That is a lot.

We have a cross, uh, gallery here.

And this is the only, uh, cross-shaped gallery

in this part of the system.

So I like to think that they picked this place

because of the cross shape.

CORJAN: So, this symbol here

looks suspiciously like a menorah.

It does.

On the other side here, circle and dot.

ALEX: Yep.

Over here, four-dot cross.

RICK: That's remarkable.

CORJAN: Perhaps they left their breadcrumbs

on the ceiling.

Mm-hmm.

CORJAN: Maybe they took their treasure here

on their way up north.

PETER: Incredible.

CORJAN: Maybe, you know, they took their treasure here.

Let's not forget we have, you know, the circle and dot,

the four-dot cross that you have

-on the H+O stone on Oak Island. -Mm-hmm.

CORJAN: So, perhaps, you know, that's also, uh,

an indication... (stammers) ...of the destination.

NARRATOR: At the Caestert stone quarry--

a 12th-century tunnel system in the Netherlands,

where members of the Knights Templar

are believed to have once kept their sacred treasures

before transporting them to North America--

Rick Lagina and members of the team

have just been shown carved symbols that also appear

on the so-called H+O stone,

which was discovered on Oak Island back in the 1920s.

RICK: If they put these up there, they're saying something.

Then their beliefs are encapsulated within...

the context of a treasure.

Something that was incredibly important to them.

I think you're seeing that up there.

My belief is that whatever happened on Oak Island

is an Old World treasure wrapped up in an Old World mystery.

I think what we're seeing is

a possible route to the New World.

You flee suppression in France,

you find your way to the ocean

and you make your way to the New World.

Along the way you seek shelter with a group of people

who could easily hide you in here.

Yeah. Yeah.

NARRATOR: Is it possible, as Corjan Mol believes,

that members of the Knights Templar

once stored their priceless treasures

in the Caestert stone quarry before ultimately taking them

across the Atlantic Ocean to Oak Island?

If you see same symbols here in the Old World

that you see in the New World, specifically on Oak Island

and in close proximity to Oak Island,

is it possible it's just random?

I personally think not.

Hopefully, that will be impactful in the near future.

They weren't just running for their freedom.

They were running to protect something.

And what they were running to protect

perhaps was with them,

i.e. a treasure.

There's a message within each of these symbols

and we need to understand what they're trying to tell us.

Maybe part of that answer is in Valkenburg,

where we have a, uh, Templar catacomb.

I think we should take a look there, too.

That would be great.

So, why don't we leave?

-CORJA: Let's go. -PETER: Okay.

NARRATOR: As their quest for answers

to a 229-year-old mystery continues,

can the Laginas and their team find proof

more than 3,000 miles away

that Oak Island is home to a treasure

that could re-write history as we know it?

It is certain that they will follow the trail of clues

wherever it leads

and keep searching for valuables

where the evidence directs them.

But perhaps the greatest unknown that remains to be answered

is, as they dig closer to the truth,

will a deadly curse stand in their way?

Next time on The Curse of Oak Island...

We are definitely drilling in the right spot.

There's a big, whopping bunch of metal. I want to hit it.

JACQUO: Under this castle is a dungeon

where we found Templar symbolism.

Perhaps there are answers down below.

CORJAN: This symbol here,

I've seen in Templar prisons before.

It's a Viking symbol.

GARY: When this cone is rolled over,

we should be finding something medieval.

JACK: I'm just trying to figure out

how this made its way underneath the boulder.

That doesn't happen naturally.

This is astounding.
