Researchers recently uncovered a stone burial slab which many believe Jesus Christ's body may have been laid on following his death, USA Today reports.

The original surface of the tomb was uncovered in the Church of the Holy Sepulchre in the Old City of Jerusalem during restoration work and has been covered by marble cladding since at least 1555 A.D., National Geographic reports.

The marble cover was pulled back, and researchers were surprised by the amount of fill material beneath the covering, Fredrik Hiebert, an archaeologist-in-residence at the National Geographic Society, and a researcher on the restoration project, told National Geographic.

“It will be a long scientific analysis, but we will finally be able to see the original rock surface on which, according to tradition, the body of Christ was laid,” Hiebert told National Geographic.

National Geographic is filming the restoration process for the Explorer series, which will air in November.

According to the Bible, the body of Jesus Christ was laid on a burial bed, or slab of limestone following his crucifixion.

Christians believe that Christ was resurrected following his death, and women who came to anoint his body three days after the burial reported that Jesus’ remains had vanished.

The Church of the Holy Sepulchre was built by the Emperor Constantine in 325 A.D., and has long been considered by Christians to be the spot where Jesus Christ was buried, AP reported.

In June, a team of experts began renovations on the church and the Edicule or ancient chamber that held Jesus’ tomb, AP reported.

The exposure of the burial bed will allow researchers to answer questions about the original form of the tomb, Antonia Moropoulou, of the National Technical University of Athens, told National Geographic.
