Vatican archeologists have discovered a sarcophagus which tradition says contains the remains of the apostle St. Paul.
The white marble sarcophagus can be traced back to the fourth century.
It is buried under the main alter of St. Paul's outside the walls of the Basilica.
It is the second largest church in Rome.
The sarcophagus was discovered during an extensive four-year excavation.
The goal of the excavation was to make the sarcophagus more visible for visitors.
