Scientists Close in on 300-Year-Old San José Shipwreck Holding £15 Billion Treasure

Scientists now believe they have found the long-lost San José galleon, a Spanish warship that sank over 300 years ago with what could be one of the richest treasures ever discovered beneath the sea. New underwater images and archaeological research published in the journal Antiquity offer strong evidence that a wreck located off the coast of Colombia is indeed the San José, a ship believed to be carrying treasure worth as much as £15 billion—or $20 billion.

The San José sank on June 8, 1708, after it was attacked by British warships during the War of the Spanish Succession. The galleon was en route from Peru to Spain, loaded with gold, silver, and emeralds meant to fund Spain’s war efforts. A sudden explosion in its powder magazines caused the ship to sink rapidly, taking almost all of its 600 crew members to the bottom of the Caribbean Sea, where the wreck now lies about 600 meters deep.

Key evidence supporting the ship’s identity includes silver coins struck in Lima in 1707 bearing royal Spanish emblems and heraldic symbols, as well as Chinese porcelain from the Kangxi period (1662–1722). Inscriptions on several recovered cannons date back to 1665, matching the time the San José was armed. These findings make a compelling case for the wreck’s identity, strengthening claims that this is indeed the legendary treasure ship.

However, the discovery has reignited a complex legal and ethical dispute over who actually owns the treasure. Colombia claims full ownership under its national heritage laws, asserting that the shipwreck is within its territorial waters and should remain part of its cultural legacy. Spain, meanwhile, argues that the San José was a Spanish naval vessel and remains the property of the Spanish state.

Adding to the conflict, Indigenous groups from modern-day Bolivia are seeking reparations, claiming their enslaved ancestors were forced to mine the treasure that ended up on the galleon. Meanwhile, the American salvage company Sea Search Armada insists it originally discovered the site in 1981 and is demanding a share of the find, citing previous agreements and its decades-long search efforts.

Colombian President Gustavo Petro has stated he intends to raise the ship before the end of his term in 2026. However, the current phase of the operation is focused on non-invasive surveys, mapping, and analysis. No immediate recovery of treasure is planned until the site is fully studied and documented.

The San José is not just a sunken vessel—it’s a symbol of colonial history, economic ambition, and geopolitical conflict. Its rediscovery promises not only extraordinary archaeological insight but also years of legal wrangling and international debate. As scientists and governments examine the wreck, one thing is clear: the story of the San José is far from over.
