Tonight on
The Curse of Oak Island...

We're in
a sweet area right here.

There's metals in the water.
High metals.

We're looking for the one thing.

This could be
where it's coming from.

- Yeah.
- Exactly.

- What are you seeing, Peter?
- Definitely a void

that goes on for a long ways.

We're gonna get
to the bottom of this.

There's a heck of a lot
of bricks up here.

Maybe it'll lead to a vault.

Wow.

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.

So, BN-14, we're down to 108.

It's not really that soft yet,
Steve. -That's right.

At the top of a new morning

on Oak Island, brothers Rick
and Marty Lagina and their team

hope to finally pinpoint
a legendary treasure

at the bottom of the Money Pit.

We're in an area
of the Peacock where

we've had an open void,
and, hopefully,

we're gonna be able
to find it again.

We're in a sweet area
right here,

so, if it's there,
we'll find it. -Exactly.

Today, the team
is drilling borehole BN-14

in the so-called Peacock,

an area where
they have discovered

loose soils between 50
and 150 feet underground

that sits nearly ten feet
above the solution channel.

Whoa. Whoa, whoa, whoa.

Two weeks ago, while drilling

just three feet west
of their current location,

the team found
a possible man-made cavity

measuring ten feet high.

So, we're into
the hole. -[Charles] Okay.

And when
an underwater camera was placed

in the cavity, they captured
images that suggested

it could be
an offset treasure chamber.

The shapes,
the tapering, the alignment

appears of human origin rather
than the natural environment.

Now, the team has two goals.

First, they hope to drill
into the mysterious void again

and determine
just what is in there.

And second,
penetrate the solution channel

several feet deeper,

where high traces
of precious metals

have been repeatedly detected
in the water.

Who knows what
the next core's gonna bring us.

From a scientific
standpoint, I am very curious

as to what in the heck
the Peacock is

and hope to get
some data on that.

Is it an offset treasure chamber

right above
the solution channel?

We have a core, gentlemen.

Knowing what's
in these strange areas

that are associated
with the solution channel

could point us to where
the treasure is.

So, I think we're
on the right track.

What do you got,
Adam? -118.

- 118
- Thank you.

BN-14, 108 to 118.

Looks like it's getting
a little soft.

Let's have a look.

Firming up down here, but

we're getting quite loose
up above. -Are we ever.

Yeah. Wow.

So, this is really
coming apart. -[Steve] Yeah.

So, I would say

there's a little
too much sediment.

It's not completely washed-out.
It's not a void.

No. Not yet. -We're getting
close to the void.

Yeah. -[Terry] So,
hopefully, we're gonna

- find the offset chamber.
- Yeah.

We'll get some evidence
of that treasure. -Yeah.

From here on out,
it gets interesting.

As the drilling continues

in the Money Pit area,

Rick and members of the team
arrive on Lot 8,

located on the western side
of the island...

You got a lot more
work done. -[Laird] Yeah.

But I have to ask, Laird,
what do you think?

It's weird.

...where members
of the team are investigating

a massive boulder
that Laird found one week ago,

and which appears
to have been placed

above evenly spaced stones.

Because you can see
defined edges.

Right.

- You can see it coming up here.
- Mm-hmm.

Which is odd.

My curiosity was instigated
by the placement

of those stones on the outside.

They're almost regularly placed.

- Yeah.
- Right? Yeah.

And there's
some evidence of a void,

a space of some sort
under there.

Yes.

You know, the more this shapes
up to be something made

rather than natural,
the more curious I become

of the December Triangle
on Zena's map.

Mm-hmm.

The December Triangle?

In 2016, the late author
and researcher Zena Halpern

presented the team
with a map of Oak Island

that she believed
had been created by

the Knights Templar
in the 14th century.

Curiously,
it marked a number of locations

in French that,
when translated to English,

corresponded with known sites,
such as the Money Pit,

the Stone Triangle,
and the swamp.

Could Doug be correct
that this boulder feature

might align
with another site on the map

known as the December Triangle?

If this is one point
on that triangle,

there could be
a couple more out there.

Well, we might be able
to help you solve

part of the mystery.
Peter has a camera. -Yeah.

- Okay.
- Now, after Laird

and the archaeology team

have begun
to excavate a possible

artificial void
under the boulder,

the team will use
an inspection camera

to look for important clues
beneath it.

Peter, put the camera down,

- let's see what we see.
- Okay. Where do I go? Yeah.

- Right over this way.
- Okay.

It has been manipulated.

We don't know of any efforts

in any of this
historical narrative

associated
to this work on Lot 8.

But I think the thing
that's in everyone's mind is,

what could possibly
be underneath it?

What are you seeing, Peter?

Definitely a void
that I'm following.

It certainly goes on
for a long...

...ways.

I think it's very soft
underneath the rock,

which is odd.

Okay.

I hit some compact soil.

Is it at the very bottom, Peter?

Yeah.

I'm able to follow it down,

but this material
is much more compact.

It's firm enough that, four feet
away, I can't push through it.

- Four feet's a long ways down.
- Yeah.

If something was buried there,

you'd almost expect them
to backfill it. -Mm-hmm.

Can you do a test pit right

where Peter is? -Yeah. That's
exactly what I was thinking.

That way, there's two purposes.

- What's down and-and what's in.
- Yeah.

Both Fiona and Laird
are of a like mindset,

and that is that we're
making progress in a very

archaeologically disciplined way
and they would be resistant

to a drastic change
in the approach,

i.e. a large excavation,
and I currently agree with them.

I think we got everything we can

- from the camera.
- Okay.

Let's clear it off
and see what we get.

Well, I know one thing,
no pun intended,

but you're gonna get to
the bottom of this. -

Okay. Well, I think
we will let you continue

- to do your work.
- Okay.

- Okey doke. Good luck.
- See you later.

As the work
on Lot 8 continues...

It's gonna be interesting
to see if we find more stakes,

if-if there is a line that's
gonna take us right across

into the south end of the swamp.

...Craig Tester, Tom Nolan,

and other members of the team
continue searching for clues

in the northern region
of the swamp.

It looks like
it's heading towards

- that vault that we found.
- Mm-hmm.

- I'd love to find another one.
- Yep.

They are hoping
to uncover more sections

of a cobblestone path
found one year ago in this area

that was lined
by eight-sided survey stakes

and led to an empty
brick and slate vault.

The vault-like feature in
the map is outlined exactly like

the vault-like feature
found in the swamp to a T.

A vault which appeared to be

drawn in a 19th-century book

containing Masonic codes
and a map of Oak Island

that researcher John Edwards
believes may be connected

to missing treasures
of the Knights Templar

and a related order
known as the Knights of Malta.

What's that right there?

Is that a stake right there?

Maybe.

I think it is.

We'll know in a minute.

Oh, yeah.

Yep.

And there we go again.

Eight sides on this.

Yep.

That's amazing. Very consistent.

That kind of goes to the center
area towards the vault.

Yeah. It's moving
in that direction.

Al, wouldn't mind scraping
in that area a little bit more?

And see those rocks that are
at the very bottom there?

- Yes.
- I want to see if

there's any kind of
platform or not.

- Perfect. Yep.
- Okay.

As we're uncovering, uh,
some of the material,

you know,
we're starting to uncover rocks.

I don't know
what it's telling us yet,

but it's a starting point.

If it's a road,
then we can follow it.

Maybe it'll lead
to another vault.

It looks like they're
kind of placed in there,

- but, uh...
- Yeah.

It seems like
it's an awful lot of

swamp material underneath it.

- Yeah.
- Um...

Well, sort of like the
stone path on the other side.

- Same-same idea.
- Yeah.

So why is a rock sitting
on swamp material? -[Tom] Yeah.

And why is the wood in there
mixed with it? -[Craig] Yeah.

Yeah, I think
I'll text Dr. Spooner,

- see if he can come out here.
- Yeah.

It'll be interesting to know
what he says about it.

- Tom. Craig.
- Dr. Spooner.

- How are you?
- Good. Good.

We have some questions,
hard to believe. -Yep.

In the northern region

of the Oak Island swamp,

Dr. Ian Spooner arrives
to inspect a possible

stone structure that was just
uncovered by the team

and marked with
an eight-sided wooden stake.

We're finding, right in
through here at least,

a number of rocks. Okay?

And it seems to still have
peat underneath it,

like it wasn't sitting
on sea level. -[Ian] Right. Yep.

It just seems so crude,

and yet, thought through.

And so, I wonder if, somehow,
that ties into some of

the other structures that we're
seeing the stakes in the ground.

Yeah. Okay. -
So, I'll just take a look.

As Tom and I
were looking at the stones

underneath the sand, we felt it
was a road or path or something.

It's different from what we see,
uh, further into the swamp.

So, our thought is,
let's get in there

and see if we can find
something of significance

that may help date
when this structure happened.

I see there's...

- Is that a cut piece?
- Yeah.

It's what-what we want.

- And it was down deep?
- Yeah.

- It was down here in the peat.
- Good.

I can test this to try
to date this structure.

- Okay.
- Whew.

So, what I know for sure

is this is at least
three rocks thick

- where I was digging.
- Mm-hmm.

Same with the stone road.
I-I find it amazing,

- it was built on swamp.
- A lot of swamp. Yeah.

Okay. Well, I'll take that
back. -[Craig] Okay.

- Thank you very much.
- Thank you, Dr. Spooner.

We have come to learn
that every time

you dig in the swamp,
you're gonna be surprised.

We have found artifacts.

We have found constructions,

all of which imply

the swamp is very complex,
probably as complex

or maybe even more so
than the Money Pit.

Wow. There's a heck of a lot
of bricks up here.

This load was full of bricks.

At least four of 'em.

Those bricks do remind me
of the bricks

that were associated
with that vault over there,

- so...
- Oh, yeah.

We're getting more and more
bricks. I'll toss 'em over.

Bricks?

Found near the newly uncovered
stone feature?

Could Craig be correct

that, perhaps, they are related
to another vault in this area?

All the things in the swamp,

the vault, the stone road,

the stone path, all these stakes

that are going
throughout the area,

it was all there for a purpose.
Man put it there.

It means man was doing something
very significant here.

We got to figure out what.

Between what looks like
a stone road

and the lot of bricks we found,
you know, I think

we're finding something
significant here.

Maybe we can follow it
that way and see if

we can come up
with another vault.

I mean, it's definitely moving
to that side of the swamp,

- so it'll be interesting...
- Yep.

...to see just where
they take us from here. -Mm-hmm.

- Okay. Good day.
- Thanks, Al.

Excellent. Thank you, guys.

- Thank you.
- See you, mate.

The next day...

So, lady and gentlemen,

we find ourselves
in another war room.

And today, Emiliano
has kindly offered to come

and give us an update
on his research.

Thank you, sir.

...Rick and members of the team

meet with Emiliano Sacchetti.

With what we found on the island

and especially the known
historical connection

between the Knights of Malta
and Nova Scotia,

I was excited to see

what we could find
in the historical record.

In light
of discoveries made on Lot 5,

such as two
17th-century buttons,

a number of Venetian
trade beads,

and a 17th-century folded coin
that all may be connected

to the Knights of Malta...

What I'm presenting today
is almost a year of work.

...Emiliano
has uncovered new research that

he is eager to share
with the team.

I conducted this research in
Rome, in the Vatican archives,

in Ottawa,

at Library and Archives Canada

to research the presence

of the Knights of Malta
here in Nova Scotia.

Today, I'm-I'm presenting
some new information

about Isaac de Razilly,

who was the governor of Acadia.

In 1632,
a wealthy French Naval captain

and Knight of Malta
named Isaac de Razilly

led a battalion
of approximately 300 men

to establish
the colony of Acadia,

which is now
modern-day Nova Scotia.

And curiously,
he built his headquarters--

known today as Fort Point--
on the LaHave River,

just 15 miles south
of Oak Island.

So, what we know
is that this guy

sailed from west coast
of France,

and in two months,
arrived here in Nova Scotia.

He landed in LaHave,
where de Razilly built his fort.

He was travelling with
Nicolas Denys, a businessman.

We know that, from a journal
that Nicolas Denys kept

during this time in Acadia,

and there's a passage,
annotation,

that is really interesting
and revealing to me.

And it says,
"Setting out from LaHave,

we went clear to the head
of this bay,

where we found some other
island with big oaks."

Is it possible
that the island of oaks

described in the journal
connected to Isaac de Razilly

was referring to Oak Island?

If so, was de Razilly
simply exploring?

Or was it because
he had knowledge of something

of great value hidden there,

based on
his high-ranking position

in the Knights of Malta?

Among the other things
in Ottawa,

what I found very interesting
is two documents.

The furniture, clothes,
fabric, silverware,

everything
that was in his possess.

It's very detailed.

One of these two inventories

was written here
in Nova Scotia, in LaHave.

The other inventory,
a year later in France,

where de Razilly family
was residing.

If you compare
the two inventories,

some items
that were listed here in LaHave

are not present
in the inventory a year later.

Between Nova Scotia and France,
we have missing items.

In July of 1636,

Isaac de Razilly
died suddenly of unknown causes.

His belongings
were inventoried in Acadia

before being shipped back
to his family in France.

However, when
a second inventory was taken

of what was actually delivered,

several items were not included.

So what are the missing items?

We have a copper astrolabe,

we have two flintlock muskets,
and two leather-covered chests.

Uh, what did those
leather-covered chests contain?

Maybe they
have been used

to move
out of LaHave,

Razilly's riches.

For now, we know that
it never reached France.

And I think I also have some

interesting information

about his potential presence
here on Oak Island.

Oh, really?

Is it possible that
Razilly's missing items

have been hidden here

on Oak Island?

- Quite interesting.
- Yeah.

In the war room,

Emiliano Sacchetti has revealed
documented evidence

that two chests of valuables
belonging to Isaac de Razilly,

a Knight of Malta who was
headquartered near Oak Island,

went missing after his death
in 1636.

We know that the
Knights of Malta did own

or have in their possession
some relics.

The order brought relics
from the Holy Land,

so maybe one of the mission

Razilly's men undertook was
to move things to Oak Island.

I've always objected to the idea
that what was done here

was to protect temporal wealth,
meaning money. -Mm-hmm.

- There's something else.
- Oh, yeah. Oh, yeah.

If you're gonna go through
the effort of, uh,

engineering a-a system
like we believe

happened here,
it's going to be more than just

your chest of coins, probably,
that you put down there.

Yeah.

And two more of the missing
de Razilly items are

two flintlock muskets.

That reminded me of what
you guys found in Lot 8,

and this is this artifact.

You guys know it,
and it's an amazing piece.

This is a-a flintlock plate
coming from a firearm.

In 2021,

while metal detecting on Lot 8,

just yards from where the team

is currently investigating
the massive boulder feature,

Gary and Marty discovered
an iron flintlock plate

from a musket, that could date
as far back as the 17th century.

So, we can't rule out
the possibility that this

was part of one of the missing
muskets of Isaac de Razilly.

Mm-hmm. -[Doug] What you're
saying is we potentially have

some circumstantial
evidence that they had

a presence here on the island.

Yeah. Well,
you said it better, but...

Is it possible
that Emiliano has found

a key piece of evidence

supporting the theory
that Isaac de Razilly

and the Knights of Malta

brought Templar-related
treasures to Nova Scotia,

that were eventually
hidden on Oak Island?

The folded coin,
the Venetian beads, the buttons,

the majority
of the artifacts are 1600s,

so maybe it's connected
with the Knights of Malta.

Isaac de Razilly
was here in Nova Scotia.

There are two missing
leather-bound chests.

Might they be associated
with a treasure here?

It's possible.

Emiliano, we've had many talks
how important research is,

and this just
reaffirms that fact.

Ultimately,
it will be responsible,

or partially responsible, for

understanding what happened
here on Oak Island.

So, I applaud you for doing it.

I thank you for doing it.
Doug and Judi as well.

But there is a search component.

It's starting to look like
we have to go to Fort Point.

And I think everyone
sitting around this table

would all agree,
so if we can arrange that,

it could be
an important component

of finding the answers here.

- Yeah.
- And we need to go do it, so...

- Okay.
- Sounds good.

Thank you.

Later that day...

...while members of the team

carefully dig beneath
the boulder on Lot 8...

All right.
Here's the next one, Scott.

Okay. -
...several yards to the south,

Gary and Scott search
for more clues where Gary

has already detected
and flagged buried metal objects

close to where the team
found the musket flintlock.

Scott.

- Let's check it out.
- Yep.

I'd like to find
something connected

to that feature behind us, mate.

Let me see if I can pinpoint it.

- Got it. Got it.
- Oh, you got it?

- Oh. Shotgun shell.
- Oh.

You can't win 'em all,

but like I always tell the guys,

you got to dig through the trash
to get to the treasure.

All right, mate. I'll put it
in the pouch, and we'll move to

the next flag, which is
just over there. -Move on.

We have to keep
digging in the area

and, hopefully,
recovering artifacts because

one of the great things about
metal detecting on Oak Island

is you never know what's
gonna come out the hole next.

All right.
Here's the next one, Scott.

- Good hit?
- Yeah.

Good nonferrous hit.

Should be just there.

Nice one.

Sounds a lot better now.

Come on. Be something good.

Got it out.

Ooh. I like finding lead.

It's a lead splash.

It makes you wonder
how it gets here.

- Yeah.
- In the middle of nowhere,

there's one random
piece of lead. -Yeah.

And you know what you had to
go through to dig that out.

Now, I know Katya

found a really nice bale seal

just over the wall there.

Um, there's a chance it could be

a folded over piece
of bale seal. -It's possible.

Could Gary be correct

that he and Scott may have found
another piece of a bag seal?

Like the one
recently found in this area

that could date back
as much as seven centuries?

But I'll put it
in the bag, mate,

and we'll put the flag in there.

Sounds good.

Because the team
has recently created

a so-called heat map
to help them organize

their discoveries
across the island

according to their potential age,

Scott is marking the site
of this find with a flag.

Nice one, mate.
A little bit of mystery lead.

Moving on.

And the next flag is over here.

All right. Let's see
what this one sounds like.

Great strong signal just there.

And we are a stone's throw away
from that feature now, Scott.

- It's certainly a rocky lot.
- Yeah, it is.

I like the rocks, mate.

It helps trap targets
from sinking deeper.

What have we got here?

I know what it feels like,
and I'm hoping it is.

We have got
some big chunks here.

I believe this is it.

I think this is
a big piece of iron, look.

See that, mate?
There's a big, big chunk of iron

right there.

You could chunk around that,

because if this
is an old piece of iron,

it would really help us
try and explain

this feature behind us on Lot 8.

I agree. We need
an artifact or something

- to tie this to man.
- Yeah.

It's out.

Oh, what have we got here?
Woo-hoo!

Amazing.

Oh, what have we got here?

It's a couple of links of chain.

Oh, yeah, it is.
Older style chain as well.

- It's oval links.
- Yeah.

On Lot 8, Gary and Scott

have uncovered what could be
another important clue.

It's obviously hand-forged,
by the look of it.

You can feel it has some weight
to it, like older iron.

Yeah.
I know these oval links are old.

And I mean,
chains go back all the way

to Roman days and beyond.

I'd be curious to see the scan
of that when they X-ray it.

See how collapsed
these links are

from what kind of load
it may have been pulling.

Yeah. That's a good point.

Just recently, we found
some really big ox shoes

in a line
heading towards this feature.

We have a-a large boulder
right there

that we're suspecting
may have been moved into place.

If you were
gonna move that boulder,

you would need chain
and some really big oxen. -Yeah.

Oh, yeah, mate. These could be
the missing links.

Could Scott be correct?

Is it possible
that this iron chain

might be related
to the massive boulder,

where the team has found
evidence suggesting

that it was lifted and placed
above a ring of smaller stones?

When you look at the connections

to this mysterious
stone boulder,

it doesn't get any better
than this piece of chain.

Chains are used
for pulling and hauling.

This could be the missing link
we've been searching for

to find the treasure.
I like the sound of that.

But we know where we got to go

to get the results
on this, mate.

It's back to the lab.
All right. -Perfect.

Plant that sweet flag
of victory,

and we'll see what Emma
has to say about the find.

- Sounds good.
- Good digging, Scotty.

Good finding, Gary.

As Gary and Scott

conclude their search
on Lot 8...

I think we missed
the void at 148 feet,

but we should hit the bottom
of the solution channel

- in this hole.
- Yeah.

...Rick and Dr. Spooner

arrive in the Money Pit area,

where borehole BN-14 has reached
a depth below 150 feet,

but unfortunately,
encountered no evidence

of the potentially
man-made void.

I mean, I'm still
interested, because we're

at a depth that is right
verging on the solution channel.

- Right?
- Yep.

And we're close to your favorite
borehole, C.5N-13.5.

- Yep.
- Every time you tested

that borehole,
it returned metals.

It's connected
to the solution channel.

Yeah.

The team is hopeful
that a major discovery

could still be made

once the drill reaches
the solution channel

because it was
just eight feet away

in borehole C.5N-13.5,

where water tests
conducted in 2024

revealed some
of the highest traces

for gold and silver
that have ever been obtained.

We have a core, gentlemen.

It'll be interesting
to see what it is.

Yep.

We didn't find the void.

So, again, my mantra is:
"stick to the plan,

cover the area,
use all the data we obtain

to dial in on where
the treasure might be located."

It's that simple.

- What do you got here?
- 198.

- 198?
- Yeah.

- Okay.
- Okay.

We're probably now
into the solution channel.

Okey doke. Let's cut it open,
see what we got.

Um...

So, is this sand
generally seen at this level?

It is a little odd
at that depth to-to have it.

It's pretty good sand, isn't it?

Yeah. -It's a clear path
of water movement.

Absolutely. Like, this would

move water very, very nicely.

This could be what you'd expect
in a void that got washed.

There's metals in the water,
high metals.

But where is it coming from?

Yeah. -[Ian] If you have
a till that has gold,

and it gets washed,

it leaves behind the precious
metals that are in the till.

But what we will
for sure take is

a sample,
a large sample of this.

Right.

We'll take
that section and bag it.

Several weeks ago,

Dr. Spooner began a new kind
of testing procedure

to look for precious metals
in soils

that the team recovered
from the solution channel

nearly 50 feet to the southwest.

Those results are still pending,

but could be much more accurate

than water tests in locating
the possible treasure.

We've spent a great
amount of time and energy

doing soil samples
because that's where

the signature, if you will,

of metals in the water
would be held.

- All good?
- A little more.

So, we will continue
the soil and water sampling

from these depths to try
to ascertain whether or not

there are precious metals
in the area.

That's good.

It's unfortunate that we
didn't find the one thing here,

but we have to remember
the point of this exercise

was to define the solution
channel to a greater extent.

That really was the goal here.

There's always
the one chance that

there's actually
something there.

So, that's the way
you have to look at it.

Every time and every way,

- you have to remain positive.
- Yes.

It's on to the next one,
gentlemen.

You bet.

golden sunrise on Oak Island...
arrator] Witr

We've uncovered this weird area.

These rocks are super flat,
and they're, uh, not in situ.

They're on top of
what looks like subsoil,

but that's also loose.

...Rick and Gary
arrive on Lot 8,

where members of the team
have just found

more evidence
of man-made workings

next to the massive boulder.

There's no flat rocks
in this whole feature here.

They look like
stepping stones from here.

They kind of
do look like pavers, huh?

- They are very unusual.
- Hmm.

You should ask Terry
where these types

of stones might have come from.

Yeah. I think it's a great idea.

- We've never seen 'em before.
- No.

I think the archaeologists

are actually quite excited
about the flat stones

around the Lot 8 boulder

because they look for anything
that is out of place.

Something you might not
expect to find.

- Hi, guys.
- Hey, Terry.

Ethan has uncovered some thin,
flat stones that-that

just don't look like
anything else around here.

Okay. -[Rick] So,
we asked Terry to come down,

uh, because he's a geologist,
and he can

give us his opinion about
what the feature might be.

Is it natural? Is it man-made?

Okay. That's interesting.

That's granite.

Those almost look
like flagstones,

which would show that
somebody was trying to flatten

- or pave an area.
- Yeah.

- Which is curious in itself.
- Sure.

Let's have a look at them here.

Those types
of flattened granite sheets,

it wouldn't happen naturally,
I wouldn't think.

And have you seen it
anywhere else on the island?

No, I haven't seen anything
quite like that.

It's very, very odd. Yeah.

Putting a name like flagstones

to that is reminiscent of the
description of the Money Pit.

As they started digging,
they came across flagstones

laid out in a pattern,
like a floor.

In 1795,

when Daniel McGinnis
and his two friends,

Anthony Vaughan and John Smith,

began digging in a strange
13-foot-diameter depression

on the eastern end
of Oak Island,

they found a uniform layer
of flagstones two feet deep

that were packed together,

as if forming a seal
for something buried below.

They would soon realize
that they had discovered

the original Money Pit.

Is it possible

that these granite flagstones
were buried next

to this massive boulder
for a similar reason

as those found
at the top of the Money Pit?

If so, just what might the team
find buried beneath them?

This is getting
weirder and weirder.

Oh, yeah.

To me, the importance
of this structure--

we'll call it
the Lot 8 mystery--

it's singularly unique.

I think everyone is now
firmly committed to the idea

that it was manipulated
by people.

I don't know what to make of it.

I hope,
as the process continues,

and it will continue, uh,

that there will be
some answers forthcoming.

Yeah. -It'll be interesting
what's under here.

- Mm-hmm.
- Yeah.

And in order to do that,
I guess we will leave you

- to your efforts.
- Okay.

Gary and I will go back
to work. -Good luck.

Thanks, Terry.

Later that afternoon...

You know, we find
ourselves in the lab again.

I know this is a chain
from Lot 8.

That's all I know about it.

...Rick has gathered
with other members

of the team in the lab,

where Emma has just completed
her analysis

of the iron chain

found one day ago on Lot 8.

So, you two were instrumental
in the find and the recovery.

Why don't you tell us
about the item

- in front of us?
- Yup.

This piece of chain was 20 yards

west of the big boulder,

and it's an older-shape link.

And I'm hoping
that this is an old piece,

because of the artifacts we've
recovered on Lot 8 already.

Yeah.

So, what have you found out
about it?

So first, I'll just
bring up the CT scan,

just to get a clearer view
of the original shape.

That looks really well made.

Yeah. So, it's forged.

The seams-- there's no
butt-ends, there's no welding,

obvious welding signs.

All of these point
towards a non-modern link.

So, we'll just move on
to the composition.

It's a very pure iron.

It's averaging at 99%.

And I'm just
gonna say it off the bat,

good signs
for pre-1800s date range.

- Brilliant.
- Yeah.

What date
are you putting on this?

Okay. So, I'd say,

comfortably 1600s,
based on the composition.

But technically,

- it could go back to the 1500s.
- Wow.

So, I'd say,
comfortably 1600s,

and could technically go
into 1500s.

- Brilliant.
- Yeah.

In the Oak Island lab,

Emma has determined
that the pieces

of iron chain found on Lot 8,

and near the massive
boulder feature,

could date back
well over a century

before the discovery
of the Money Pit.

Especially because

you do still see some traces
of phosphorous.

So, that in there is aligning

with the iron industry
during that time period.

You see from the image,
though, it's had a hard life,

a rough life, because you can
see on the corners how

- it's thin on the curve.
- Oh, the wear patterns.

Yeah, the wear patterns.

It went through
some heavy workload.

Well, if you were moving
a 50,000-pound boulder.

- Exactly.
- You know,

it's 20, 25 yards away
from that big boulder

on Lot 8
that was really curious, so,

if it was placed there,
this may have been

- the chain that hauled it there.
- Hmm.

Chains hang around
for a long, long time.

Those dates certainly align

- with the Knights of Malta.
- Yeah.

That timeline fits.

- Yup.
- We know that, right?

We know they were in Fort Point.

- Isaac de Razilly, right?
- Yeah.

Could Rick be correct

that the team has found
another piece of evidence

that may tie
the Knights of Malta

to the Oak Island mystery?

If so, could this chain
also be related

to the flintlock
that was found on Lot 8,

the massive boulder feature,

and perhaps the two
missing treasure chests

that once belonged
to Isaac de Razilly?

Here we have something

that we all probably
walked past 20 times.

I'm talking
about this big boulder.

Well, this says
several things, doesn't it?

The first thing you think is,

if this is really
that significant,

and the archaeologists seem
to think it is,

how many other things
like it are all over the island?

The other thing
we also have is a metal chain,

found by Scott and Gary.

It probably wouldn't be
so significant,

except it's found
very near the big boulder.

So, I am very curious
as to what this might be.

We don't know what's
underneath that boulder yet.

Can you imagine
when that boulder's moved?

Maybe this chain was used
to lower something down there.

There might be
some other chain there,

but a different color.
Maybe gold?

Ooh. That would be sweet.

There's all kinds
of possibilities

about what
this boulder represents.

Sure, it could
be covering a shaft.

There could be an interment

of something precious
or significant underneath it.

I think everyone is
now firmly committed

to the idea
that it was manipulated.

We found multiple artifacts
in the area.

I think it's an important facet

to helping solve
the Oak Island mystery.

Well, it's a pretty cool find.

It's an interesting
possible connection.

You have this intriguing boulder
on Lot 8, right?

We have interesting finds
in close proximity

that we have yet to explain,
which is very interesting.

It begs for more data,

but in order to do that,
we've got to get out back

- and find some more.
- Yeah.

- Let's get to work.
- Yeah. Hopefully,

there's some more
answers there. -Okey doke.

Thank you both.

- See you later.
- See you.

Despite the frustration

that Rick, Marty
and the team face

in locating a vast cache
of gold and silver

that has been detected deep
in the Money Pit,

they have now discovered
another man-made feature

near the surface that
may also contain something

of great value
and historical importance.

Could both of these sites
on Oak Island prove

that a generational conspiracy
took place

to hide sacred riches from
the Holy Land in North America?

The evidence suggests

that the team's
tireless efforts to find out

will be well worth the reward.

Next time on
The Curse of Oak Island...

Welcome to Fort Point Museum.

We brought a few artifacts.

Do you think that

the Knights of Malta
would've used

- beads like that?
- Yes. They may well have

visited Oak Island.

This is the kind of loose slurry

of mud that we were looking for.

That speaks to a chamber.
Or the offset chamber.

That's where treasure can hide.

We're all extremely interested
in the Lot 8 feature.

We need to see
what's under that rock.

- Wait. You see that?
- Oh, my god. There's a pearl.
