A New Vault, Ancient Wooden Fence on Oak Island—Is the Oak Island Swamp Man-Made?

A thrilling week of discoveries has unfolded on Oak Island, as Rick and Marty Lagina, alongside their trusted team, made significant progress in their quest to uncover the island’s long-hidden treasure. The latest findings, including a stone pathway and a mysterious vault-like structure, have experts buzzing, and many are speculating that the secrets of Oak Island may be closer to being unlocked than ever before.
This week, the team’s focus shifted to the northern region of the swamp, where they unearthed what appeared to be two man-made features. One of these was a stone pathway, the other—a small vault or cellar-like structure. The stone path, believed to be made from uniformly sized rocks, was an immediate indication that something purposeful had been constructed in the area. Ian and Alex, two members of the team, noted the distinct arrangement of the rocks, which they said could not have occurred naturally due to the uniform size and placement.
As they continued to excavate the area, the team uncovered what seemed to be a vault or small chamber, submerged in the swampy conditions. The first item retrieved was a large, iron object, believed to be part of a chest, which ignited speculation that the feature could have been used to hide valuable items. The possibility that this was a treasure vault, perhaps related to the Spanish silver coins reportedly discovered by former Oak Island landowner Anthony Graves in the 1800s, has added a new layer of intrigue to the island’s mysterious history.
In the 1850s, Anthony Graves purchased a significant portion of Oak Island, and while he was not an active participant in the treasure hunts for the Money Pit, rumors have circulated that he stumbled upon a significant hoard of Spanish silver coins on his property. This new discovery, linked to Graves’ property, raises several questions. Could this be the very vault where Graves hid his treasure? Or, was it a structure created long before his time? The team is eagerly working to answer these questions and determine the true purpose of the vault-like feature.

A Historic Discovery: The Vault and Its Potential Connection to Graves
As the team carefully examined the vault-like structure, they found a piece of wrought iron and a crank handle, which appeared to be part of a much larger mechanism. The presence of these artifacts suggests that the feature was constructed to serve a specific purpose. Could it have been a hiding place? Or perhaps it was a secure storage unit for valuable items, like the coins Graves reportedly found?
Archaeologist Laird Niven and archaeometallurgist Emma Culligan led the team in analyzing the artifacts, and based on their findings, the crank handle and pipe were dated to the late 1700s—well before Graves’ time. This discovery challenges the assumption that Graves was the original builder of the structure, suggesting that the vault could predate his occupation of Oak Island by several decades.
Further analysis of the crank handle, which was found alongside a piece of brick, provided even more evidence that this vault may have served as a storage place for valuable objects. Niven and Culligan speculated that the structure could have been part of a larger, more complex system designed to safeguard treasures—perhaps even the legendary Oak Island treasure that has eluded treasure hunters for over two centuries.
With the artifacts suggesting that the vault could be much older than Graves’ occupation, the team is now considering the possibility that the structure was built by an unknown party, possibly even linked to the treasure’s original creators. The presence of a vault hidden in the swamp, combined with the stone path leading to it, could indicate that the area was purposefully constructed to conceal something valuable—possibly a treasure of immense historical significance.
Survey Stakes: A Link to the Past?
In addition to the vault discovery, the team unearthed another critical piece of evidence in the northern swamp—an old wooden survey stake. The stake, found buried deep in the swamp, appears to be consistent with the descriptions provided by Fred Nolan, a previous Oak Island landowner and treasure hunter who conducted surveys of the island in the late 1960s. Nolan had previously unearthed a series of similar wooden stakes, which he believed were used as survey markers for a massive construction project on the island, dating back to the 1500s.
Carbon dating of the stakes from Nolan’s 1969 excavation revealed that they originated from the 1500s, which could further support the theory that Oak Island was involved in an ancient, large-scale construction project. Could the vault and stone path uncovered this week be part of this historical project? And if so, what was the purpose behind these structures?
The wooden stake found by Rick and Marty Lagina, along with the team’s discovery of additional survey markers, suggests that the swamp may have been artificially created as part of an effort to connect two previously separate islands. If this theory is correct, it could change everything we know about Oak Island and the extent of the construction that took place long before the treasure hunt began.

What’s Next for Oak Island?
As the team continues to examine the vault-like structure and the wooden survey stakes, the mysteries surrounding Oak Island only deepen. The connection between the stone path, the vault, and the survey markers could provide the missing link in solving the 230-year-old treasure mystery. The team is planning further excavations and tests to determine the full extent of the structures and artifacts found in the swamp.
Rick and Marty Lagina, along with their dedicated team, are determined to push forward, even as new challenges arise. With more discoveries on the horizon, the stakes have never been higher. Could the treasure of Oak Island finally be within reach? Only time will tell. But one thing is for certain—the mysteries of Oak Island continue to captivate and intrigue treasure hunters, historians, and viewers alike.
The journey on Oak Island is far from over, and with each new discovery, the team inches closer to uncovering the truth about the island’s hidden past. What lies beneath the surface of the swamp? Will the vault hold the key to Oak Island’s legendary treasure? Only further investigation will reveal the answers to these age-old questions.
