The San José Galleon, often called the "Holy Grail of Shipwrecks," has become the center of an intense legal, ethical, and cultural debate. This Spanish warship, sunk off Colombia's coast in 1708, carried a treasure now valued at $20 billion. For nearly 40 years, multiple parties—Colombia, Spain, the Qhara Qhara Indigenous community, and a U.S.-based treasure-hunting firm, Sea Search Armada—have contested ownership. Each stakeholder invokes distinct legal frameworks, from national sovereignty and sovereign immunity to Indigenous rights and commercial salvage agreements. The case raises critical questions about cultural preservation, reparative justice, and the ethics of commercializing heritage. Could collaborative stewardship provide a balanced resolution to protect history, honor diverse claims, and preserve environmental integrity? Explore how this case reveals the complexities of underwater cultural heritage in our interconnected world.
