ISRAEL (WVLT) -- Believers call it the holiest site in Christianity. Deep in Jerusalem's old city is the church of the Holy Sepulchre and the very tomb where Jesus is believed to have been placed before his resurrection.
In a National Geographic documentary, archaeologists sort through centuries of layers of marble, and fill dirt as well as the destruction of thieves and souvenir seekers.
What they found was described as astounding. A marble slab with a cross carved into its surface, thought to date back to the Crusades in the 1500s and part of the original limestone bed where Joseph of Arimathea placed Jesus's body on Good Friday.
After 60 hours, it's said that the tomb was sealed again, perhaps never to be reopened again.
