The final episode of The Curse of Oak Island for the 2024 broadcast year—specifically the Season 11 finale—aired on May 7, 2024. In real terms, titled "The Lost Treasure of the Knights Templar," this two-hour special marked the conclusion of the most recent chapter in the Lagina brothers' decade-long quest. As of right now, there are no new episodes scheduled for the remainder of 2024, with the show traditionally going on hiatus during the summer and fall months before returning for a new season in November.
For fans accustomed to the rhythm of Rick and Marty Lagina’s annual excavation cycle, the May finale signals the start of the long off-season wait. Understanding exactly when the last episode aired, what it revealed, and what comes next requires a look at the show’s production schedule, the specifics of the Season 11 conclusion, and the confirmed future of the franchise.
The Season 11 Finale: "The Lost Treasure of the Knights Templar"
So, the Season 11 finale aired on Tuesday, May 7, 2024, on the History Channel. It was a supersized two-hour event, a format the network often reserves for season closers to maximize the dramatic weight of the final findings. The episode picked up on the intense activity in the Money Pit area and the Lot 5/Stone Road corridor, where the team had been chasing a massive anomaly detected by seismic scanning and ground-penetrating radar Easy to understand, harder to ignore. That alone is useful..
Throughout the season, the narrative arc focused heavily on the "Gardiner's Road" theory and the potential for a deep, man-made tunnel system connecting the swamp to the Money Pit. The finale brought several key storylines to a head:
- The Big Dig at the Money Pit: The team utilized a massive caisson (the "Big Dig" approach) to bypass the unstable soil and water flooding issues that have plagued treasure hunters for centuries. The finale showcased the extraction of core samples and wood fragments from depths previously unreachable with standard drilling.
- Scientific Analysis: A significant portion of the final episode was dedicated to the lab results. Viewers saw the team consulting with geologists, dendrochronologists (tree-ring dating experts), and metallurgists. The discovery of worked wood (timber cut with tools rather than natural breaks) at significant depths provided the strongest evidence yet of human activity far below the surface.
- The Knights Templar Connection: True to the episode's title, the finale leaned heavily into the historical theory linking the island to the Knights Templar. Researchers presented correlations between the island's geometry, the "Nolan's Cross" formation, and Templar navigation methods. While no gold chest was pulled from the ground, the episode framed the geological findings as "treasure" in the form of data—proof of a massive, pre-industrial engineering project.
The episode ended not with a definitive "we found the gold" moment, but with a strategic pivot. Marty Lagina, ever the engineer, emphasized that they now possess the data to target the next dig with surgical precision. The final scenes showed the heavy machinery being winterized and the war room maps being updated for the next phase Easy to understand, harder to ignore. Surprisingly effective..
Why the Show Ends in May: The Production Calendar
If you are wondering why the "last episode of the year" airs in May rather than December, the answer lies in the logistics of filming in Nova Scotia. The Curse of Oak Island is not a studio show; it is a documentary crew embedded in a live, active archaeological excavation It's one of those things that adds up. And it works..
The Digging Window The primary excavation season on Oak Island runs roughly from October/November through April/May. This window is dictated by the Atlantic Canadian climate.
- Winter (Nov–Apr): The ground is frozen, which actually helps stability in the Money Pit area (preventing shaft collapse) and allows heavy machinery to operate on solid ground without sinking into the muskeg.
- Spring Thaw (April/May): As temperatures rise, the water table spikes. The infamous "flood tunnels" become active, and the soil turns to slurry. This makes deep excavation dangerous and technically impossible without massive dewatering efforts.
- Summer/Fall (June–Oct): This is the off-season for digging. The team uses this time for data analysis, permitting, engineering design for the next season's structures, and—crucially—filming the "war room" segments, interviews, and historical reenactments that fill the episodes airing the following winter.
The Broadcast Lag Because the crew films the excavation in real-time during the winter, the episodes you watch in January 2024 were actually filmed in January/February 2023 (or late 2022). The production team edits roughly 18–20 episodes per season. By the time the finale airs in May, the crew has been off the island for weeks, and the machinery has been shipped off-site or stored Easy to understand, harder to ignore. Took long enough..
So, the "last episode of the year" is technically the last episode of the broadcast season. There is a six-month gap (June–October) where no new content airs because no new digging is happening Most people skip this — try not to..
What Happened in Season 11? A Recap of the Journey
To appreciate the finale, it helps to contextualize the season that led there. Season 11 was widely regarded by the fan community as one of the most scientifically rigorous seasons to date. The "shotgun approach" of drilling random holes gave way to a targeted strategy driven by 3D Seismic Survey data acquired in the previous off-season.
Worth pausing on this one.
Key milestones of Season 11 included:
- On the flip side, The Swamp Investigation: While the Money Pit took center stage, the team continued to investigate the "Ship Anomaly" in the swamp. Practically speaking, The "Baby Blob" and "Big Blob": Seismic data revealed two massive underground anomalies. Worth adding: this shifted the narrative from "is there anything there? Which means " to "what was the industrial scale of the operation here? 3. The "Baby Blob" was investigated early in the season; the "Big Blob"—a massive void or chamber structure deep beneath the Money Pit—became the primary target for the finale. Artifact Volume: The volume of artifacts recovered—British military buttons, pottery shards, human bone fragments (dated to the 1700s), and significant amounts of worked wood—was higher than previous seasons. "

- The Garden Shaft Re-entry: The team successfully stabilized and re-entered the historic Garden Shaft (originally sunk in the 1860s), allowing them to drill laterally from a safe, dry platform into the Money Pit zone. The finale confirmed the presence of a structured stone foundation or wharf beneath the muck, supporting the theory that the swamp was once a constructed harbor.
The Future: Season 12 and Beyond
The most pressing question after the May 7 finale is: When does Season 12 start?
Confirmed Renewal History Channel officially renewed The Curse of Oak Island for a 12th season. Rick and Marty Lagina, along with Prometheus Entertainment, have confirmed their return. The Laginas have repeatedly stated in interviews that they are committed to seeing the project through to a resolution, whether that means finding the "main deposit" or scientifically proving the negative That's the part that actually makes a difference..
Expected Premiere Date Based on the last decade of scheduling history, Season 12 will almost certainly premiere in November 2024 (likely the first or second Tuesday of the month).
- Season 10 Premiere: Nov 1, 2022
