The Ongoing Dispute Over the San José Shipwreck

The San José, a Spanish galleon sunk off Colombia's coast over 300 years ago, is regarded as the world's most valuable shipwreck, with its cargo of gold, silver, and emeralds valued at billions. Yet, ownership of the treasure remains hotly contested.

Claims have emerged from the Colombian and Spanish governments, a U.S. salvage company, and various indigenous groups in South America. Legal battles are underway in both Colombia and the U.S., with the matter now before the Permanent Court of Arbitration in The Hague.

The Colombian government aims to raise the wreck for display in a museum, while treasure hunters emphasize the potential commercial worth, estimated as high as $18 billion. In contrast, archaeologists argue the site should be preserved, as it serves as a grave for approximately 600 individuals who perished when the ship sank.

Carla Rahn Phillips, a historian familiar with the wreck, states, “It’s a complicated situation with no easy resolution.” The ship was accidentally destroyed by British forces who fired a cannonball that ignited its powder magazine, leading to its swift sinking.

The wreck remained undiscovered until the 1980s when a U.S. company, Glocca Mora, claimed to locate it. Subsequent disagreements over rights led to ongoing legal disputes, with Colombia asserting its own discovery of the ship in 2015.

Additionally, the Spanish government argues that the San José remains state property, while indigenous representatives claim their ancestral rights to the treasure, which they assert was plundered during the colonial era.

Amid these tensions, Colombia has released underwater footage of the wreck, showcasing its remains and the precious cargo resting on the ocean floor. Estimates of the treasure's value vary widely, leading to skepticism among experts about the financial claims made by treasure hunters.

The situation highlights a broader dilemma regarding the ownership and exploration of shipwrecks, as there are approximately three million sunken vessels globally, many lacking clear ownership laws. The United Nations has provided some guidelines, but many countries, including Colombia and the U.S., have not ratified them, complicating the legal landscape.

Archaeologists advocate for preserving wrecks like the San José in situ to honor their historical context and human stories. Juan Guillermo Martín, a Colombian maritime archaeologist, emphasizes that the treasure should remain submerged, preserving its archaeological integrity and the memory of those who lost their lives.
