The biggest haul of precious metals ever found at sea has been discovered on a shipwreck in the Atlantic Ocean.
The 200 tonnes of silver are worth about £150 million.
It was stashed onboard SS Gairsoppa, a British cargo ship, which was sunk by a German submarine in 1941.
The wreck of the ship was found 300 miles off the coast of Ireland, 4700 metres underwater.
Now remote-controlled robotic submarines will be sent down to collect the treasure haul.
