Colombia’s government announced the discovery of new artifacts from the legendary Spanish galleon San Jose, following the first robotic exploration of the shipwreck, which sank in 1708 near Cartagena.

The San Jose, often called the “holy grail” of shipwrecks, is believed to hold treasures worth billions.

The recent exploration, covering an area equivalent to 40 soccer fields, revealed new items including an anchor, jugs, and glass bottles, and provided more detailed information about the wreckage.

The site has been declared a “protected archaeological area” to preserve its heritage, CBS News has reported.

The exact location remains secret to protect it from treasure hunters, while disputes over the ship’s ownership continue between Spain, Indigenous Bolivians, and a U.S. salvage company.
