Cannon, three coins and a cup taken from San José, a 1708 wreckage that could hold items worth billions of dollars

A cannon, three coins and a porcelain cup are among the first objects recovered by Colombian scientists from the depths of the Caribbean Sea where the legendary Spanish galleon San José sank in 1708 after being attacked by a British fleet.

The recovery is part of a scientific investigation authorised by the government last year to study the wreckage and the causes of the sinking. Colombian researchers located the galleon in 2015, leading to legal and diplomatic disputes. Its exact location is a state secret.
