The Story

What is claimed · what is sourced · what is still disputed

In 1820 the city of Lima was about to fall to the revolution sweeping South America, and the Spanish viceroy made a fateful decision: rather than let the rebels seize the wealth of the colonial church, he loaded it onto a ship for safekeeping. Gold candlesticks and ingots, jeweled stones, and two life-sized solid gold statues of the Virgin Mary holding the infant Christ went into the hold of the trading brig Mary Dear, under an English captain named William Thompson.

Thompson could not resist it. Somewhere out on the dark Pacific he and his crew cut the throats of the guards and the priests, threw the bodies overboard, and turned pirate. They ran for Cocos Island, a green volcanic rock five hundred miles off Costa Rica, and there, the story goes, they buried the treasure of Lima. It did them no good. A Spanish warship caught the Mary Dear, and the crew was tried for piracy. All of them hanged except Thompson and his first mate, who bought their lives by promising to lead the Spanish to the gold, then bolted into the jungle the moment they landed on Cocos and were never caught.

Thompson died without ever going back for it. And so began the most relentless island treasure hunt in history. Hundreds of expeditions have torn at Cocos. One German, August Gissler, lived on the island alone for nearly twenty years digging for it. None of them found the Lima gold, and today Cocos is a protected national park where digging is flatly illegal.

So the loop never closes. Either two golden Madonnas and a church's fortune are still under the roots of an island you can see from a dive boat, hidden by a man who took the secret into the jungle and the grave, or the whole thing is a tale too good to check. Hundreds have given years to finding out, the island has told no one, and now the law has locked the door and thrown away the shovel.

The lure: Church gold & jeweled statues (~$200M+)

Working Theories

Competing explanations — what people believe, held against what the record can and cannot support

01

One camp holds the treasure is still buried under landslides or in a flooded cave; another holds Thompson never buried it, or it was quietly recovered long ago.

02

Costa Rica now bans all digging on Cocos, so any modern search is illegal without a permit.
