After a decade of anticipation since its discovery, the legendary San José galleon has begun yielding its secrets. In a significant milestone for maritime archaeology, Colombian authorities have recovered the first tangible artefacts from the fabled 18th-century Spanish warship — a bronze cannon, three coins, and a porcelain cup — from nearly 2,000 feet beneath the Caribbean Sea.
The San José, dubbed the “Holy Grail of shipwrecks” for its immense treasure, sank in 1708 during a clash with an English fleet while en route to King Philip V of Spain. Of its roughly 600 sailors, only 11 survived. Located off the coast of Cartagena, Colombia, in 2015, the wreck has remained a closely guarded state secret, its exact position shielded amid ongoing international disputes.
The newly surfaced items provide a tantalising glimpse into the vessel’s opulent cargo. A bronze cannon bearing the inscription “Sevilla” was brought up in remarkably good condition, alongside delicate porcelain cups and a bowl. High-resolution underwater imaging had previously revealed dozens of coins scattered across the seabed near the stern — identified as “cobs” and “macuquinas,” hand-struck silver pieces minted in Lima in 1707, the very year the galleon set sail. Some bear the royal symbols of Castile and León, emblematic of Spain’s vast empire. Chinese porcelain from the Kangxi period (1662–1722) and 17th-century cannons dated to 1665 were also observed at the site.
Archaeologist Daniela Vargas Ariza highlighted the diagnostic value of these finds: “Hand-struck, irregularly shaped coins — known as cobs in English and macuquinas in Spanish — served as the primary currency in the Americas for more than two centuries. The finding of cobs created in 1707 at the Lima Mint points to a vessel navigating the Tierra Firme route in the early eighteenth century. The San José galleon is the only ship that matches these characteristics.”
The ship is believed to hold one of the richest hauls ever lost at sea: an estimated 11 million gold and silver coins, emeralds, and other precious cargo potentially worth around £16 billion today. Underwater drone footage has captured bronze cannons, swords, clay vessels, and twinkling trinkets strewn across the seafloor, painting a vivid picture of the catastrophe.
For years, historians assumed the 62-gun galleon exploded after being ambushed. Colombian officials now propose an alternative explanation: hull damage may have led to its demise. This evolving understanding underscores how modern technology is rewriting the narrative of the 300-year-old tragedy.
Ownership Battle and Cultural Heritage
The wreck sits at the heart of a complex international ownership dispute. Colombia asserts sovereignty, viewing the San José as part of its cultural heritage since it lies in its territorial waters. Spain has also staked a claim, while the U.S. firm Sea Search Armada maintains it discovered the site in 1981 and is seeking £8 billion in compensation. Former President Juan Manuel Santos rejected the company’s assertion, stating the Navy located the vessel at a different position.
Current President Gustavo Petro, who has maintained his predecessors’ stance, personally inspected the recovered cannon and porcelain bowl during a media presentation. Emphasising research over treasure hunting, Petro described the expedition as focused on scientific and historical inquiry rather than mere salvage.
The artefacts are now undergoing conservation in a dedicated laboratory to prevent deterioration upon exposure to air and light. Further recovery efforts are expected to proceed with caution, balancing archaeological integrity with the wreck’s extraordinary historical significance.
As these initial treasures emerge, they not only illuminate the final voyage of the San José but also reignite global fascination with one of the greatest unsolved maritime mysteries — and the immense fortune still resting on the ocean floor. The “Holy Grail” has begun to reveal its golden touch, three centuries after it slipped beneath the waves.
