Tonight on the Curse of Oak Island.

This is X marks the spot.

Yep. Let's get that can down hole and find this thing. We're good to go, guys.

I found very similar crosses from the 13th century.

You can say quite securely they were made before 1460.

It was one of the things Fred found on the island.

Is this the key to unlock the mystery? Is this the key to Nolan's cross?

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 Mysterious fragments of human bone

and a lead cross Whose origin may stretch back to the days of 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.

As a new day begins on Oak Island,

Brothers Rick and Marty Lagina are more convinced than ever that they are close

to solving the 223-year-old mystery.

Just one week ago, while excavating a shaft known as H8 at a depth of some 170

feet, the team encountered evidence of what they believed was the so-called

Chapel Vault, the mysterious 7-foot-tall box first discovered by treasure hunters

William Chappell and Frederick Blair in 1897.

But when the drill team from Irving Equipment Limited tried to penetrate the

wooden object, they were shocked to learn that not only did their massive

steel caisson fail to enter the vault, it actually pushed it farther down and

out of its path.

Something was in front of the can, and we were pushing it for a while, and

that's when the drilling got done. Oh, it's still in there then.

Let's push to the side.

An even bigger setback to the team occurred during a meeting in the war

room while choosing the next drill site, when Rick and Marty's friend and

partner, Craig Tester, announced that he would be leaving the island for the

remainder of the summer. I make a motion we dig one more well yet this year right

here. Do I have a second?

Well, it's up to the other guys around this table, because when I'm heading out

of here, I'm probably...

Not coming back, did you?

You'll always be here whether you're here or not.

The testers, they suffered a great loss with Drake.

He loved this place. He loved working with his father and his brother. So we

are pushed, if you will, to complete the task at hand.

This is a chance to finish it.

You know, I don't know how to say it exactly, but I want to try and finish

this for Drake. Can we name it after my brother, too? Of course you can.

Thank you.

Let's find it for everyone.

Take it down nice and slow.

Now, while the team from Irving Equipment Limited continues the

preparations for the new steel case shaft known simply as DMT. Right there.

Brothers Rick and Marty Lagina, along with their team, have gathered in the

war room hoping to obtain new information on what may be.

the most important discovery ever made on oak island a lead cross

look we're all very intrigued by by the cross the person that we should

reference really is jerry glover he gave us access to or got us access to the the

prison tower and dome and uh alex i believe he has sent you some follow-up

photographs you want me to get him on the phone absolutely i think we we all

should have some questions for him okay

Just one week ago, while exploring the shoreline along Smith's Cove, Rick

Lagina and metal detection expert Gary Drayton found the mysterious lead object

near the area where just one year earlier they had found evidence of an

ancient irrigation system known as a French drain.

I would say that it's somewhere in between 1200 and 1600.

I've seen that shape before. I saw a carving like that in the Templar prison

in Dome.

Incredibly, the cross was an almost exact match to carvings made by members

of the Knights Templar, which Rick Lagina and two of his nephews were

recently shown by Templar expert Jerry Glover on the walls of a 14th century

prison. in Dome, France.

First time that came out of the ground, I said I had seen that before.

So here is the side-by-side image.

That is strikingly similar.

I mean, it's not similar. It's identical, as far as I'm concerned.

Jerry, I believe we've sent you a photograph of the cross, and we were

wondering, you know, what your thoughts were on it.

Without it being properly analyzed, it's impossible to say exactly how old, but

it seems to resemble the deeply incised crucifixion graffiti

at Dom.

When I saw that, I thought it rang a bell, so I had a look at my pictures of

medieval graffiti from England, and I found very similar crosses on the pillar

in the nave of a 13th century church.

in a village called Whitchurch in Buckinghamshire.

There's also on the same pillar a cross of Jerusalem graffiti, which is like we

saw a dome and is indicative of crusaders.

So Jerry, I'm looking at this pillar from England, and these pellets and the

sort of crosses with the bases also match a lot of the graffiti and dome.

Do you draw any conclusion from that?

We know the ones at Dom, of course, were made by Templars, and there's the

possibility that the ones at the church were also made by Templars. It's very

good evidence for a common source for both.

Seems a fair conclusion, yes.

As I hope you can see, there's a graffito on the base of the pillar. It

says 1416, and examples of dated medieval graffiti are...

extremely rare, and that's one that I've discovered myself.

Jerry, is it fairly conclusive then that the graffiti is contemporaneous with the

inscription of 1416?

Is that for sure? Or is that to the best of our knowledge?

No, I think what it probably signifies is that that date

is probably the latest.

It could have been made at any time earlier.

to the building of the church in the 13th century, we can say quite securely

that they were made before 1416.

So if this is the same symbol that we're seeing in the dome and in the pendant,

is that of any meaning if we try to put a tentative date on our pendant?

Yes, I mean, just looking at its basic iconography, it certainly has that 13th

century look about it.

Who might be wearing such a thing or having such a thing?

From that time, it could be anyone in Christendom, from an ordinary person to

a knight, a clergyman. It's made for personal use, made by a Christian, I

would imagine, to wear themselves.

Depictions of Jesus Christ on a cross, also known as a crucifix, date as far

back as the second century.

Those made of lead, and most resembling the one found at Smith's Cove, were also

known as mortuary crosses and were generally worn during times of plague in

an effort to ward off evil and disease.

The thing is very curious, especially, you know, the obvious question is how in

the heck did it end up on a beach in Nova Scotia?

It's very unusual.

If you had to opine, is it... Templar, likely Templar, or more generically

Christian? Could you call it a Templar cross?

It may be, but without a little bit more evidence regarding the age of the item,

can't really say any more than that with regard to its Templar connection.

We're going to have to have experts give us an opinion, people who are very well

versed in religious iconography. But the 13th century, really?

It's surely a... very, very significant discovery.

But again, in terms of its connection to a specific theory, I don't think we're

there yet.

Well, I'll tell you what, Jerry, we will continue our research.

If you have any more information that you think we may find of interest,

please remain in touch. We on our end, as this moves forward, we will stay in

touch with you.

I'm sure you'd be interested in whatever results we find.

Thank you again from all of us. Thank you. Cheers, Jerry.

He said it's probably medieval.

It's ancient.

Everything he said was consistent.

So we're going to keep going with that. See where it leads, as you always say.

Look, the obvious conclusion is to keep pursuing this. Yeah, and we're not going

to get it done sitting here. Back to it.

While his brother remains on Oak Island to supervise operations at the Money Pit

site,

Rick Lagina and Charles Barkhouse have traveled some 50 miles northeast to

Waverly, Nova Scotia.

They have arranged for what they believe will be a very important meeting with

fellow Oak Island property owner Tom Nolan, the son of legendary treasure

hunter Fred Nolan, who passed away early last year.

I do think that the torch has been passed to Tom from his father.

And my hope is that he'll say, you know what?

As a way to honor my father's and my father's legacy, you know, I'll work in

concert with you guys.

Yeah.

T.J. Nolan Construction.

This will be it.

I was hoping to work with Red, and now we've lost part of what my brother calls

the fellowship of the day, in that we would include Mr.

Nolan in that.

Now Tom will take his seat at the table, hopefully.

Hey. Hey, Tom. How are you? How are you doing?

Good to see you again. How are you? Hi, Tom. Charles.

Can I jump in there?

Yeah.

How's things going on Oak Island today?

Uh, you know, the Oak Island, what I call the emotional roller coaster.

I wish I had X marks the spot.

As you all know, it's, I mean, your father spent a lifetime doing this.

Yeah. Oh, sure. I mean, it's been a part of my life, you know, as long as I can

remember.

I don't know if I have the passion for the treasure hunting, Dad had, but, you

know, it certainly, it's always interested me and probably always will.

This has to be a bit emotional for you. Oh, it is. Look at your father's life's

work.

He spent hours, untold hours, working on this.

Unfortunately, he just did not bring it to an end.

So, here we are.

Here we are.

You know, it's my hope that we can in some way, shape, or form work in

concert, work together to solve this.

Whatever I can do, Rick, you know, to try to help you guys to facilitate this

thing and hopefully bring it to an end once and for all. You know, I'll gladly

step up.

What I'm really hoping to see are the... You would like to look at the maps? I

would, absolutely.

Okay.

We have seen them for a short period of time. You know, your father came down.

Well, what these are, I mean, these are basically 50 years of his work, you

know, his survey work down on the island, you know, plotting everything he

thought was important.

You ran through the fields? Yeah, I spent my time with the mosquitoes in the

woods cutting survey lines, but no, the actual survey work was dead, you know,

100%.

These are basically 50 years of his work, plotting everything he thought was

important. You know, the field work would all be recorded in his books and

then put on the maps.

Look at the amount of survey lines on this map.

There's hundreds.

It was a lifetime to put it together.

A land surveyor by trade, Fred Nolan first became involved in the Oak Island

mystery when he was invited to create a detailed map.

of all 140 acres of the island by M.R. Chappell in 1961.

After purchasing six four-acre lots near the middle of the island in 1963,

Fred spent over half a century plotting evidence of possibly man-made markers.

He also made numerous significant discoveries, including Nolan's Cross.

You know, I guess as a surveyor, Dad got caught up in what he saw.

and thought, you know, there's something to this from an engineering surveying

background. You know, that's what drew him to it.

When Tom unrolled the first map, my thought was, my goodness, there's an

enormous amount of information here.

It's bittersweet.

Here's the maps. We have now completed total access to them.

And yet we've lost the interpreter of the maps. We've lost Thread.

We very much look forward to coming to some understanding of where these maps

may take us. I mean, I have, as you well know, and you do too, an interest in the

swamp. I believe the swamp hides some secrets. You do too. You've spoken of

it. Yeah.

Swamp's a, it's a, it's, you know, it's a strange place. I mean, we drained it

in the 70s a couple of times and, you know, Dad believed there was something,

something hidden in it. You were part of your father's process, were you not,

about... locating the survey stakes yeah we found you know the lines of lines of

stakes out in the swamp during his exploration of the mysterious triangle

-shaped swamp fred nolan discovered a number of identical evenly spaced wooden

stakes that were later carbon dated to as early as the 1500s based on his

professional experience fred was convinced that he had found the actual

survey markers used centuries ago to help create the boundaries for what he

strongly believed was an artificial body of water.

These stakes were there, and they formed perfect lines as if they were set by a

surveyor. Is some of that data on the maps?

It's all on the maps.

It's all there.

Let's put this together.

Let's put it to bed.

Let's do it.

That's great, guys. Look, before you go, there's just something I wanted to show

you.

One of the things Fred found on the island, I don't know exactly when, but

it's a key.

And it's, I know when you look at it, you're going to find it very

interesting.

I've never seen anything like that before.

It's a folding skeleton key, something I had never seen before.

It has a cross in the blade of the skeleton key, and when you fold the key,

you can see the cross in the handle. All that is very interesting.

A skeleton key found on Oak Island?

Also known as a passkey, the use of skeleton keys dates back to the 8th

century BC, with the invention of the first bronze and iron keys during the

Roman Empire.

Stripped down to their most essential parts, a narrow shaft and single

rectangular tooth, they served as universal master keys that could open

and close numerous locks on everything from doors to safes, or as a pick for

thieves who wanted to break into them.

But what was a skeleton key doing on Oak Island?

Could it have been used to open a number of different treasure chests buried

centuries ago?

The fact that it folds is very curious.

It's unique.

In many ways, it's emblematic of what we just proposed to do.

Is this the key to unlock the mystery?

Is this the key to Nolan's cross?

I mean, working together, I think we can do this together.

And again, thanks for the trust. Maybe this is the start of something.

Absolutely.

One day after their productive meeting with Tom Nolan, Rick Lagina and Charles

Barkhouse. arrive at the home of Oak Island resident Dave Blankenship.

Hello. What do you got there, Rick?

I don't have your spendables, but this might lead you to the spendables.

This is Mr. Nolan's maps.

Now, armed with Fred Nolan's maps, Rick is eager to examine them for possible

clues.

There's a lot of information on here, as you well know. Yeah.

So why don't we take a look?

To be able to hold in our hands Fred's life's work, it's almost bequeathed to

us from beyond the grave.

Here's a man who committed a large portion of his adult life to this

passion, to this pursuit, and there's an enormous amount of information, and

enormous doesn't begin to quantify Fred's 50 years of research.

I can't even imagine how much work was done.

Look at the amount of survey lines on this map.

There's hundreds.

It's probably a couple thousand here.

He ran every one of these lines physically through the island, and there

are probably thousands.

Not every one was important.

We're going to have to parse out what's relevant from what's not relevant.

That's the initial process.

Look over there. Check that out. Look at the triangular stones right there.

I see that.

There's so much information on here.

He must have surveyed practically every rock that was visible on his property,

thinking it connected to something.

There's almost survey lines to every rock that's here, that's on the surface,

obviously. Yep.

Unlike most Oak Island treasure hunters, including his rival, Dan Blackenship,

Fred Nolan believed the key to solving the mystery could be found by examining

evidence above the ground, rather than below it.

He also believed that the real treasure site was likely to be found at the swamp

rather than in the money pit.

Here's what I think. I think these are the survey stakes.

You think those are?

Okay. Those are them right there.

Yeah? Those?

If only he were here. I know.

I would do anything for a time with him again.

Me too.

There's information there, but there's no legend.

There's no scale.

There's no orientation.

So there's a lot of work that remains to be done with the maps before we actually

use the information in the field.

We have to be diligent and we have to be patient.

His gift to us is we have these maps and now we can duplicate his processes to

see if these maps are really to scale. Yeah.

Look, we've done as much as we can do. Let's roll them up and get after it.

Okay.

It is a moment of great anticipation for brothers Rick and Marty Lagina, as they,

along with Charles Barkhouse and metal detection expert Gary Drayton, head to

Lot 12 to begin their new search efforts on property now belonging to Fred

Nolan's family.

All right, guys.

Today is the day, right?

Yep, I'm all for it.

For the first time since Fred Nolan's death, his son Tom has granted the team

access to all of his father's 16 acres.

This includes the areas where Rick believes Fred made several of Oak

Island's most important discoveries, including Nolan's cross.

Here comes Jim with the backhoe.

Tom has also arranged to have his associate Jim Marr aid the team's search

efforts using a seven-ton backhoe.

Hey, Jimmy. What if you just dig a trench two feet down, all the way

roughly to where they're standing, a little bit beyond that?

Right. And we'll try to locate where this thing might be.

All right. Sounds like a plan.

Noted on Fred's maps as a location of particular importance, is an area the

veteran treasure hunter once described as an ancient dump site.

It was here that previous searchers reported finding evidence believed to be

connected to the original construction of the money pit.

Where is this dump?

It's here. You just haven't found it yet.

We have several sources that describe a dump-like area.

right near Fred Nolan's house, now Tom Nolan's house. We have Tom himself

describing his dad digging in there when Tom was a young lad.

We're looking for clues in that area as to what happened here long ago.

So Charles, you know, about the dump, I know there's not much written about it,

but what do you know?

Gilbert Hedden, 1936, he finds shards of pottery with traces of mercury in them.

And mercury has actually been found in the money pit too.

That goes back to that whole theory of Sir Francis Bacon preserving documents

in Mercury.

One of the most persistent theories as to the origins of the Oak Island mystery

points to Sir Francis Bacon, the renowned 17th century philosopher,

scientist, politician, and nobleman.

Bacon was also a leading member of the Rosicrucians, a secret society of

intellectuals. who are believed to have come into possession of the priceless

religious treasures of the knights templar some researchers believe that

bacon was also the secret author of the works credited to william shakespeare

and that he buried both the templar treasures and the original shakespeare

folios on oak island in his scientific work novum organum bacon

described a method of preserving documents in mercury allowing them to be

securely buried deep within the Earth.

Could the traces of mercury discovered at the dump by Gilbert Hedden in 1936

support the theory that important historical documents could be hidden on

Oak Island?

And might that explain why the Oak Island team found pieces of parchment

and possible leather bookbinding deep in the Money Pit area earlier this year?

Small scrappy iron.

Let me get a pinpoint.

Oh.

No.

Crusty nail.

Okay, guys, trench time. All I'm picking up is small nails.

So I'll start at that end and work my way back.

We need some shiny gold things.

Something with a date on it.

Yes.

i'm getting something it looks like iron

that's it

yeah square nail i got some water here already yeah

should we go have a look oh my god i could have the old dinner service here

look there's a big piece look yeah different look

That's a lot of pottery.

Well, it looks like we've hit the dump, guys.

Oh, another piece.

Here, take that.

Good eye, Charles.

I think you're the pottery shard champ now.

That kind of like hit the jackpot here. There's another little piece right here.

I think our dump is right there, Rick. It's this perfect cross-section. We

found it.

It doesn't go through this way. You're finding all kinds of bits of pottery and

stuff right there. Another piece.

Locating the dump, finding it, realizing that the stories were true.

Yeah, this is a successful date.

We got to figure out the oldest thing here because that might tell us who was

here at the times we're wondering about.

The date.

It's always about the dates.

From the beginning, we've tried to look to the past.

and try to confirm what the past has taught us. And now, today, we've taken

story, gone into the field, and corroborated that the story is real. And

that's important as we move forward.

While Rick, Marty, and members of the team continue their search of the dump

site on Tom Nolan's property, Alex Lagina and

Jack Begley have traveled 60 miles north to the Dawson Print Shop at the Nova

Scotia School of Art and Design in the city of Halifax.

I'm anxious to meet him. This is like right in his wheelhouse.

They are meeting with Joe Landry, an expert in medieval bookbinding, who

specializes in the study and restoration of ancient manuscripts.

We have found some interesting things that we think you'd be able to help us

with.

Jack's got them, and I would love to take a look if we can.

It kind of looks like it could be some old parchment.

Several weeks ago, while searching the spoils excavated from borehole H8 in the

Money Pit, Jack Begley and Dan Henske discovered both parchment and bits of

leather.

Leather, which when examined under an electron microscope, resembled possible

bookbinding material.

Well, please have a seat and we'll have a look. Thanks.

It is the team's hope that Joe, along with his apprentice, Catherine Taylor,

can make a positive identification of these artifacts and perhaps determine

their origin.

So we have what we think is parchment and what we think is leather from

possibly a bookbinding.

Okay. Where should we start? The parchment? Sure.

So, there you go.

Yes, yes, this would be parchment.

I guess I've been burned so many times in the past that I was almost expecting

him to say, oh, it looks like parchment, but, you know, on closer examination,

no, that's not what this is.

However, what he told us is, yeah, this is parchment. He immediately recognized

it. He said, yep, that's exactly what this looks like.

Yeah, do you want to take a look at this?

This is some of the leather we found.

Yeah, so this is quite typical of a vegetable.

tanned leather, especially calf or hide.

This material lasts and lasts.

I mean, one of the suppliers I use when I'm restoring medieval books sort of

guarantees his Allentide skins for 2,000 years, whereas goat skins are only good

for 400.

Got to save those receipts.

Yeah.

Pass them. You've got to write the receipts on parchment, too.

Yeah.

We actually brought one more piece that we were wondering if you could give us

any information on. This might be kind of a long shot.

Yeah, it's a purple piece of wood.

Any idea?

Look at this, Dan.

Purple wood.

Along with the samples of parchment and leather found in the H8 spoils, Jack and

Dan Henske also discovered a mysterious piece of wood, which appeared to have

been stained or dyed the color purple.

It's not fluorescent exactly, but it's definitely an unusual purple.

This is also, its color is very similar to an ink used in parchment.

Wow.

This is from Egypt.

How old is this scroll? About 2,000 years.

The blue is...

Tyrian blue, the royal blue that the church and the royalty would use. It was

quite literally worth its weight in gold, so it wasn't commonly used, but

it's amazing how similar the colors are. Although I feel it might be more likely

from a vegetable source like a rich red wine, I think.

How often was this color purple used?

Well, just in important church documents and royal documents.

You're kidding, right? Only for important church and royal documents?

That's right.

It looks like the same color as the piece of wood. It does look identical.

Dating back over 3,500 years to the ancient Phoenicians, the production of

purple dye was so time-consuming and costly that it was reserved for...

and became synonymous with royalty.

In fact, in the Middle Ages, so-called sumptuary laws restricted the use of

purple dyes to those in the aristocracy.

Could the presence of this purple wood, along with parchment and leather

bookbinding, be evidence that important historical or religious documents are

buried deep in the money pit?

If this was a...

A book board, and it was covered with this ecclesiastical purple leather. And

it got wet, so there could be staining.

So, wait, hold on.

That seems important.

This... There's leather that's dyed this color.

There is, yeah.

And we have leather, wood, and parchment.

You said that there's leather stained that color. Is it possible that this

wood is an analog for this wood here?

The thickness is about right for a book board.

In combination, this is the most exciting. That is true. Because without

this, that could be a shoe.

And without these, this isn't going to tell us as much as we want to know.

I think Jack and I got some really good info today.

We got a lot of answers, and we had our theories confirmed about what these

scraps of leather and parchment really are.

So I think the guys back at the island are going to be really interested in

what we learned.

Of course, things just keep getting more interesting.

Well,

that's the nature of the game, isn't it? You never know what's going to show up

next week. We'll get out of your hair. Thank you guys very much.

Bye-bye now.

head to the home of veteran Oak Island treasure hunter Dan Blankenship.

Knock, knock. Hello, Dan.

Hi, Dan.

What do you say, Rick?

How you doing? Don't get up.

Good. Hello, Mike. How you doing? Excuse me for not getting up. No, no. You sit

down.

At the age of 94, Dan has spent more than half a century living and working

on Oak Island.

determined to solve the 223-year-old mystery.

Although not as active in the search as he once was, Dan remains an invaluable

source of information and guidance to Rick and the Oak Island team.

We were out in Smith's Cove, and we were metal detecting.

And I'd like to show you what we found.

Look at that, Dan.

Whenever we find something that we deem to be an important find, we always go to

see Mr. Blankenship. And we all find the cross quite fascinating.

A significant find in our opinion, and we wanted to show it to Dan.

Lead. Yep, it's lead.

I went to France to a Templar prison, and I saw something

carved in the wall exactly like that.

I think I have a picture of it here on the phone.

This is the carving in the prison walls. Yeah. The Templars were imprisoned there

in 1307.

The similarity of it is striking, that's for sure.

I'll be honest, I came here looking for basically pirate treasure.

treasure coins, artifacts.

I wasn't a big believer in the Templar connection.

That changed my mind. Never did I ever believe that I could find something

like this on Oak Island. Something like this here substantiates that theory.

Just another piece of the puzzle that seems to...

Well, we're going to get more than one expert to weigh in on this. There may be

some scientific method that can date lead. I don't know if there is or not.

My God, they poured lead for hundreds of years. They've poured lead.

I don't know how long they go back.

A long time.

It'll be interesting to see what the experts have to say about this.

Very much so. No question about that.

I came here just...

absolutely committed to giving dan and fred some answers and unfortunately mr

nolan has passed and dan is none of us are beating father time i mean we're all

getting older so this could be an answer we find something we'll be back not if

when good to see you then

Yeah, a little bit.

For Rick and Marty Lagina and their team.

So it started.

It has started.

The anticipation for a major breakthrough in the Oak Island mystery

couldn't be higher.

You go that way just a little bit.

Good.

Yeah. There it is. Great.

Today marks the beginning of their sixth massive exploration shaft in the Money

Pit area, known as DMT.

The dig location has been named for Craig Tester's son and Jack Begley's

stepbrother, Drake, who tragically passed away last year.

Lake, morning.

All right, morning.

So, cans up, ready to start oscillating? Ready to rock.

Based on all the information we know, based on last year's work, based on this

year's work, this is X marks the spot.

Yep. As good as we can discern.

Using the information gained from the 44 exploratory boreholes completed this

year as a part of their geotech drilling program, the team has identified the DMT

location as a promising search area where they believe the legendary chapel

vault may have moved after being dislodged during the excavation of H-8.

Now we know because of the work this year, the pattern drilling, the H-8,

We're honed in on, if you will, the bottom location of Chapel's vault.

There's certainly still questions swirling around H8. And, you know, I

hate walking away with those questions unanswered. And I do believe that the

DMT hole holds much promise.

Look, everything's lining up. Let's get that can down hole and find this thing.

We're ready to go.

Thanks, man. Thank you. Appreciate it.

We're good to go, guys.

Let's hope that DMT solves the puzzle.

Hopefully his luck's on our side.

For Rick, Marty, and the Oak Island team, digging the DMT shaft in the Money

Pit area may be their final test in solving the 223-year-old mystery.

Will they soon find where a vast treasure lies buried?

A treasure consisting of everything from valuable objects to priceless documents?

Treasure of historic importance brought to Oak Island centuries ago and from

thousands of miles away?

Or might they find that the keys to unlocking Oak Island's secrets lie

somewhere much closer to the surface and in a different...

and more ingeniously protected location than anyone ever knew.

Next time on The Curse of Oak Island.

We're on an obstruction.

Oh, no.

What was pouring out?

Houston, we have a problem.

What is that? These are the type of hinges that come off chests or boxes.

Yeah. This one is from the Phoenicians.

100 BC.

This is stunning.

This is the find of the century.
