“‘Please Listen!’ – August Gissle’s Final Revelation About Cocos Island Treasure Could Rewrite History 👁️‍🗨️”

For centuries, Cocos Island, a remote and fog-shrouded isle off the coast of Costa Rica, has captivated adventurers, historians, and treasure hunters alike.

Rumors of hidden treasures, buried by pirates, have inspired countless expeditions, many ending in failure or tragedy.

Yet the story took a dramatic turn in 2025 when newly uncovered documents and testimonies revealed that August Gissle, a Norwegian treasure hunter and adventurer, had spent the last years of his life trying to disclose a secret he insisted the world must hear — a secret about the long-lost treasure of Cocos Island that could change the course of history.

August Gissle, born in Oslo in 1952, had become a legendary figure in the treasure-hunting world.

Known for his meticulous research and decades-long pursuit of pirate lore, Gissle had focused his career on documenting legends surrounding infamous buccaneers such as Benito Bonito and William Thompson, both rumored to have buried vast amounts of gold, silver, and precious artifacts on Cocos Island.

Colleagues described him as both obsessive and charismatic, often traveling alone into dangerous terrain in pursuit of the smallest clue.

On March 14, 2025, just days before his unexpected death from a heart condition, Gissle recorded a video message that has since circulated among historians and researchers.

In the footage, his voice was steady but urgent: “Please listen.

What I am about to tell you is the culmination of my life’s work.

The treasure you all seek is real, but it is not what you think.

It is not merely gold or silver.

The key lies beneath the twin waterfalls on the island’s northern ridge, in a hidden cave that has remained untouched for over two centuries.

Inside, the items are arranged intentionally — documents, maps, and relics — evidence of pirate networks and secret societies, not just wealth.

This knowledge was deliberately obscured.

Whoever controls it could rewrite our understanding of colonial trade and pirate history.

I beg you, respect the place, respect the secret, and above all, listen carefully to what follows…”

Gissle’s revelation immediately caught the attention of the global treasure-hunting community.

Teams of researchers, historians, and private expeditions have long debated whether Cocos Island housed more than folklore suggested.

While several expeditions in the early 20th century reported finding caches of coins, silver bars, and tools, nothing has ever been verified as belonging to the legendary pirate treasure.

Gissle’s testimony, corroborated by handwritten notes, sketches, and satellite imagery he had compiled, appears to provide a roadmap to something far more significant than mere riches.

The island itself, about 550 kilometers off Costa Rica’s Pacific coast, is notoriously treacherous.

Dense jungle, sheer cliffs, and unpredictable storms have thwarted explorers for centuries.

Gissle’s records describe an intricate approach: navigating through a labyrinth of jungle paths, climbing rocky ridges, and timing entry to the twin waterfalls during low water flow — conditions that change by the hour.

“He mapped it with incredible precision,” said Dr.Mariana Lopez, a Costa Rican historian who worked closely with Gissle in 2018.

“He knew the island better than anyone alive.

His maps are not just illustrations; they are encoded instructions.”

In addition to physical hazards, Gissle warned of potential legal and ethical issues.

Cocos Island is a protected national park, and any excavation is strictly prohibited by Costa Rican law.

“He wanted people to understand the importance of preservation,” Lopez explained.

“This was not just about treasure; it was about history, about knowledge that could be lost forever if mishandled.”

Among Gissle’s most intriguing claims is that the treasure may include documents detailing pirate alliances and trade agreements that were previously unknown to historians.

These records, he argued, could shed light on global commerce during the 17th and 18th centuries, showing how pirate networks influenced trade routes and political power across the Americas and Europe.

If true, these findings could redefine our understanding of maritime history and colonial geopolitics.

Gissle also left behind a series of journals detailing encounters with other treasure hunters and cryptic warnings he had received.

Some entries suggest that rival treasure-hunting groups were aware of his discoveries and may have attempted to mislead or sabotage him.

One journal from 2019 reads: “They think they can beat me, but they do not understand.

The maps are mine, but the cave has its own guardians.

Nature and history conspire together here.”

Researchers studying his work note that Gissle’s final months were consumed by travel to Cocos Island, as he conducted surveys using drones, GPS technology, and sonar scans of underwater caves along the island’s coastline.

Several of these scans indicate anomalies beneath the waterfalls he mentioned, including chamber-like structures and metallic objects buried deep within rock formations.

While verification remains difficult due to restricted access, these findings lend credibility to his claims.

Following his death, Costa Rican authorities confirmed that Gissle had applied for multiple permits to study the island in a scientific capacity.

“His work was always careful, always documented,” said Jorge Calderón, a representative of the Costa Rican National System of Conservation Areas.

“We are reviewing his materials to ensure that any exploration aligns with conservation guidelines.

His discoveries are invaluable, but the island must be protected.”

The broader public reaction has been a mix of excitement, skepticism, and fascination.

Documentaries, podcasts, and news outlets have begun exploring Gissle’s life and his final message, framing it as both a historical revelation and a personal testament.

Historians emphasize that verifying the existence of a tangible treasure may take decades, but the potential historical significance of Gissle’s notes cannot be overstated.

Experts suggest that even if the gold or silver described in folklore is never found, the combination of maps, artifacts, and potential archival materials could provide a unique window into pirate operations, early colonial interactions, and the strategies used by seafarers to hide their loot.

Some scholars believe these records may include encrypted messages and codes, providing insight into how pirates communicated across long distances in an era before modern technology.

Gissle’s final message concluded with a note that has captured the imagination of researchers worldwide: “This is not about wealth alone.

The lessons are in the stories, the connections, and the proof that human endeavor can endure beyond centuries.

Please, do not rush.

Respect the island, respect the past, and only then will you understand what I have spent my life trying to protect.”

As of 2025, international teams of historians, archaeologists, and treasure hunters are collaborating to analyze Gissle’s documents and plan potential studies under Costa Rican supervision.

While the actual treasure remains elusive, his revelations have reignited a global fascination with Cocos Island, ensuring that August Gissle’s legacy — and his warnings — will resonate for generations to come.

In the end, the world may never fully know the secrets of Cocos Island, but thanks to August Gissle’s meticulous research, daring explorations, and heartfelt final warning, the legend has entered a new era — one where history, mystery, and adventure collide in a story that will continue to captivate explorers and historians alike.
