The Curse of Oak Island: Episode 3 Reveals Their Nearest Step Yet Toward the Truth

The Curse of Oak Island Season 13, Episode 3: “Medieval Intentions” Hints at a Stunning Rewrite of North American History

Season 13 of The Curse of Oak Island is only three episodes in, but “Medieval Intentions” already feels like a turning point—one that may shift the entire narrative of the world’s longest-running treasure hunt.
From newly discovered underground voids to medieval-era artifacts pulled from the swamp, the Lagina brothers find themselves confronting evidence that is older, stranger, and far more intentional than anything uncovered in more than a decade of searching.

This time, Oak Island isn’t whispering.
It’s roaring.

A Mysterious Underground Void Shakes the Money Pit Narrative

Early in the episode, drill operators deep in the Money Pit suddenly lose their rod—a classic sign the bit has dropped into a hollow space. But this void behaves differently from the many collapses and natural pockets discovered in past seasons.

The data suggests engineering.
Symmetry.
Purpose.

Material recovered from the cavity only heightens the intrigue. Chemical tests reveal silver traces, implying that coins, religious relics, or metalwork may have once been stored or transported through this subterranean system. For Rick and Marty Lagina, this isn’t merely evidence of a treasure stash.

It’s evidence of design.

With each new core sample, the Money Pit looks less like a simple vertical shaft and more like a medieval-era constructed chamber network, built by people with resources, knowledge, and intent.

A CT Scan Reveals Hidden Designs — and Hidden Truths

One of the most electrifying moments comes when debris from the drilling spoils is placed into a CT scanner. What appears to be a dirty lump of rock transforms on screen into a piece with internal symmetry, carvings, or embedded material.

When the images appear, one crew member can only gasp:
“Oh my god.”

For the team, it’s confirmation that the objects deep below Oak Island are not accidental fragments. They are engineered—possibly by medieval craftsmen with a mission.

The Swamp Strikes Again: Medieval Artifacts Emerge

The swamp, long suspected of being an artificial structure, becomes the second focal point of “Medieval Intentions.” Using drones, metal detectors, and archaeological surveying, the team quickly identifies clustered hits that align along a curious geometric arc.

Soon, they recover a metallic object unmistakably shaped by human hands. Its style echoes symbols from medieval Europe, including the regions tied to:

The Knights Templar
The Knights Hospitaller
Early Portuguese navigators

Gary Drayton’s reaction makes it clear:
“That’s amazing.”

Every new artifact strengthens the theory that the swamp was engineered—possibly as a concealment system or as part of a larger medieval blueprint.

A Medieval Network Begins to Take Shape

“Medieval Intentions” doesn’t just add new artifacts to the Oak Island catalog.
It connects them.

The episode strongly reinforces the timeline suggested by past finds:

The medieval cross traced to France
Roman coins on Lot 5
Pottery and metal from the 12th–14th centuries
The newly revealed Portuguese coin
Lead artifacts linked to Templar strongholds

Individually, these finds could be dismissed.
Together, they form a mosaic pointing toward a medieval European presence on Oak Island centuries before Columbus.

Even Marty—often the skeptic—admits:
“This is getting hard to ignore.”

A Radical New Theory: Oak Island as a Medieval Mission Site

Historical consultants introduce a provocative possibility:
Maybe medieval builders weren’t burying treasure.
Maybe they were protecting knowledge, safeguarding sacred relics, or constructing a transatlantic waypoint.

This reframes the Money Pit entirely—from a trap-filled vault to a purpose-built repository designed by highly skilled engineers.

If true, Oak Island may have been part of a secret medieval network stretching across oceans.

The Emotional Weight of a 200-Year Mystery

Episode 3 captures something rare: the emotional gravity of a team realizing that they may be on the brink of rewriting history. Small quiet moments—Rick touching core samples, Marty staring into the swamp—reveal the weight of discovery on the entire expedition.

After hundreds of years and countless failed attempts, the evidence finally feels cohesive.

As Rick says closing the episode:
“We’re closer than we’ve ever been—not just to treasure, but to truth.”
