For more than two centuries, the mysterious island of Cocos Island has captivated explorers, historians, and treasure hunters. While the legendary Treasure of Lima is the island’s most famous story, another lesser-known legend continues to intrigue researchers—the tale of the Devonshire Treasure. Though its origins are clouded by conflicting accounts and folklore, the Devonshire legend has become an enduring part of the island’s rich history of buried riches and pirate intrigue.
Was the Devonshire Treasure a real cache of stolen gold hidden by desperate sailors? Was it connected to infamous pirates such as Benito Bonito or Captain Bennett Grahame? Or is it simply another myth that has grown larger with each retelling? Like many treasure legends surrounding Cocos Island, the truth remains elusive.
The Devonshire Treasure refers to a legendary cache of gold, silver, jewels, and valuable cargo that was supposedly hidden on Cocos Island, located approximately 340 miles off the Pacific coast of Costa Rica.
Unlike better-documented legends such as the Treasure of Lima, the Devonshire story exists primarily through oral traditions, treasure books, and accounts passed among sailors and explorers during the nineteenth and twentieth centuries. No official shipping records conclusively identify a vessel named Devonshire carrying the immense wealth described in the legend, leading many historians to suspect that multiple stories became intertwined over time.
Even so, the Devonshire Treasure has earned a place among the island’s most fascinating mysteries.
Why Cocos Island Became a Treasure Haven
To understand the Devonshire legend, it helps to understand why Cocos Island appears in so many treasure stories.
The island’s location made it an ideal refuge during the Age of Sail. Dense jungles, steep cliffs, freshwater streams, and secluded coves provided perfect hiding places for pirates and privateers operating throughout the Pacific.
Ships traveling between Peru, Panama, and Mexico frequently transported enormous quantities of:
Pirates knew these trade routes well and often sought isolated islands where stolen riches could be hidden until they could safely retrieve them later.
According to legend, Cocos Island became one of the most popular treasure vaults in the Pacific.
The Origins of the Devonshire Legend
The exact origin of the Devonshire Treasure remains uncertain.
One version claims that the Devonshire was a merchant vessel carrying valuable cargo when it fell into pirate hands. Rather than risk capture by naval forces, the pirates allegedly buried the treasure on Cocos Island before abandoning the area.
Another version suggests that surviving crew members intentionally concealed the cargo after the ship encountered disaster, hoping to return after rescue. They never did.
Some historians believe later writers confused the Devonshire story with accounts involving Captain Bennett Grahame, a Scottish sailor often associated with hidden treasure on Cocos Island.
As these stories circulated through ports and among sailors, they gradually merged into one of the island’s enduring legends.
Possible Connection to Benito Bonito
One reason the Devonshire legend remains so intriguing is its frequent connection to the pirate Benito Bonito.
Bonito supposedly operated in the eastern Pacific during the early nineteenth century, attacking merchant vessels carrying Spanish treasure. Some treasure historians argue that Bonito captured the Devonshire or acquired its cargo before hiding it on Cocos Island.
Other versions identify Bonito with Captain Bennett Grahame, claiming he adopted a new identity after turning to piracy.
Modern historians remain skeptical of these claims, but they demonstrate how pirate legends often evolved through generations of storytelling.
Whether Bonito actually possessed the Devonshire Treasure remains unknown.
A Landscape Perfect for Hidden Treasure
Part of what keeps the legend alive is the geography of Cocos Island itself.
The island is covered by thick rainforest receiving more than 20 feet of rain annually. Towering waterfalls descend into narrow valleys filled with dense vegetation.
Hidden among the landscape are:
Lava tubes
Rocky caves
Freshwater ravines
Coastal cliffs
Small protected beaches
Any of these natural features could theoretically conceal buried treasure.
Even if markers once existed, centuries of erosion, landslides, earthquakes, and tropical storms could have completely transformed the landscape.
Many failed expeditions have concluded that locating a centuries-old burial site on Cocos Island would be extraordinarily difficult.
Beginning in the mid-1800s, reports of hidden treasure attracted adventurers from around the world.
Prospectors arrived with little more than old maps and optimistic stories. Many believed they possessed secret directions leading directly to the Devonshire cache.
Instead, they encountered harsh reality.
The island’s dense jungle proved nearly impenetrable.
Heavy rainfall washed away excavation sites.
Mosquitoes, steep terrain, and limited supplies forced many expeditions to abandon their searches after only a few weeks.
Despite repeated failures, stories of near discoveries encouraged new generations of explorers to continue searching.
The Problem with Treasure Maps
Nearly every version of the Devonshire legend includes a mysterious treasure map.
Unfortunately, no verified original has ever surfaced.
Instead, researchers have uncovered numerous conflicting maps, each claiming authenticity.
Some indicate burial beneath distinctive rock formations.
Others reference waterfalls, caves, or unusual trees.
Many contradict one another completely.
Experts believe most surviving maps were likely copied, embellished, or entirely fabricated decades after the alleged burial.
Without reliable documentation, separating fact from fiction has become nearly impossible.
Did Anyone Ever Find Evidence?
Although no confirmed Devonshire Treasure has been recovered, several expeditions have reported intriguing discoveries.
Over the years, searchers have uncovered:
Old iron tools
Rusted anchors
Musket balls
Fragments of pottery
Coins from various periods
Excavated pits left by previous treasure hunters
These finds demonstrate that numerous people searched the island long before modern expeditions.
However, none of these discoveries conclusively prove the existence of the Devonshire cache.
The evidence simply shows that belief in hidden treasure has persisted for generations.
Why Historians Remain Skeptical
Professional historians approach the Devonshire legend cautiously.
Unlike famous shipwrecks supported by naval records, the Devonshire story lacks definitive documentation.
Several problems complicate verification:
No universally accepted identity for the ship
Contradictory historical timelines
Multiple versions of the legend
Confusion with Bennett Grahame and Benito Bonito
No verified eyewitness accounts
As a result, many scholars suspect the Devonshire Treasure represents a combination of several independent pirate stories rather than a single historical event.
Even so, they acknowledge that pirates frequently did bury supplies and valuables temporarily, making such legends plausible in principle.
Why the Legend Refuses to Die
Legends survive because they capture the imagination.
The Devonshire Treasure offers everything treasure enthusiasts enjoy:
Unlike treasures that have already been discovered, this story still leaves room for possibility.
Every unexplored ravine on Cocos Island could, in theory, conceal centuries-old riches.
That uncertainty continues to inspire books, documentaries, and amateur expeditions.
Modern Protection of Cocos Island
Today, Cocos Island enjoys legal protection as a Costa Rican national park and a UNESCO World Heritage Site.
Treasure hunting is heavily restricted, and excavation without authorization is prohibited. Conservation efforts focus on preserving the island’s extraordinary biodiversity rather than searching for legendary riches.
The surrounding waters are internationally renowned for their populations of hammerhead sharks, manta rays, dolphins, and other marine life, making the island one of the world’s premier diving destinations.
While these protections make large-scale treasure expeditions unlikely, they also help preserve the island’s historical and natural heritage for future generations.
Could the Devonshire Treasure Still Exist?
It is impossible to completely dismiss the possibility.
History contains numerous examples of long-lost shipwrecks and buried caches that were eventually discovered centuries later.
If treasure associated with the Devonshire legend was ever hidden on Cocos Island, it may remain buried beneath layers of volcanic soil or concealed by dense rainforest.
On the other hand, it may never have existed in the form described by later storytellers.
The absence of definitive evidence leaves the mystery unresolved.
Final Thoughts
The legend of the Devonshire Treasure occupies a fascinating place within the larger mythology of Cocos Island. While historians continue to debate its origins, the story embodies the enduring appeal of pirate lore, hidden fortunes, and unexplained mysteries.
Whether the Devonshire was an actual ship carrying immense wealth or a legend woven from several historical events, its tale has become inseparable from the island’s reputation as one of the world’s greatest treasure mysteries.
For treasure enthusiasts, that uncertainty is part of the adventure. As long as Cocos Island remains cloaked in dense rainforest and surrounded by stories of lost riches, the Devonshire Treasure will continue to inspire explorers to imagine what secrets may still lie hidden beneath its soil.
