A robot submarine has found more than 22.5 billion dollars worth of treasure in the Columbian port town of Cartagena.

The robot, Remus 6000, located the Spanish shipwreck, San Jose, more than two years ago but the exact location has been a secret.

The Colombian Government plans to create a museum and conservation laboratory to display the wreck and its contents, which includes cannons, ceramics and other treasures.
