Since its first tenuous discovery in 2015, the Colombian navy has fiercely guarded the Spanish galleon San Jose, which lies just yards below the waves in the Caribbean. Legal disputes also enmesh already complex efforts to rescue $17 billion of gold, silver, and emeralds, involving Colombia, Spain, Bolivian groups, and a U.S. salvage company.

Although they have had problems in the past, officials now hope to start lifting relics from the wreck. The first batch of salvage will commence in April. The director of the Colombian Institute of Anthropology and History, Alhena Caicedo, has underscored the shift towards historical and archaeological understanding instead of focusing on looting from the wreckage of the San Jose, sunk by a British squadron in 1708 off the coast of Cartagena.

"The ultimate dream is to raise and display such a wreck, affording, in San José's case, a view from a uniquely deep sea. But the task is awesome; very few comparables have ever been made in such a tropical resting place with so many rare preservation challenges. Colombia's navy looks to projects like the Mary Rose for guidance but faces uncertainties over exposure to oxygen and structural integrity.

International legal disputes further complicate things. Even though Colombia had found the wreck, Spain still claimed the wreck as belonging to its Spanish fleet. In its quarters, a US company claimed discovery rights. Indigenous groups in Bolivia also claimed the treasure was found in their territory, saying they had ancestral remains from there.

Given this financial temptation, Colombia has declared not to sell but to continue its insistence on fostering cultural collaboration and proper study—lost, then found by sun-drenched treasure. San José's centuries-long journey from a sunken treasure to a historical artifact is a reflection of centuries of intrigue, reflecting humanity's interest in the depths of mystery.
