text: For decades debate has raged over whether the Church of the Holy Sepulchre in Jerusalem really is the site of the most famous miracle of all.
  The shrine is supposed to contain the tomb where Jesus Christ ’s body lay for three days after his crucifixion.
  The tomb has been sealed in marble since at least 1555 – and possibly centuries longer – to protect it from pilgrims who kept stealing pieces as holy relics.
  But over the preceding centuries the church had been destroyed and rebuilt so many times there were doubts about what it contained.
  Now the tomb’s marble lid has been removed for the first time in five centuries – revealing a miraculous discovery.
  There, unseen for half a millennium, was the limestone shelf where Christ’s body is thought to have been placed.
  The researchers also discovered a second grey marble slab no one knew existed, engraved with a cross they believe was carved in the 12th century by the Crusaders.
  Archaeologist Fredrik Hiebert of National Geographic, which was a partner in the project, says: “The most amazing thing for me was when we removed the first layer of dust and found a second piece of marble.
  “This one was grey, not creamy white like the exterior, and right in the middle of it was a beautifully inscribed cross. We had no idea that was there.
  "The shrine has been destroyed many times by fire, earthquakes, and invasions over the centuries. We didn’t really know if they had built it in exactly the same place every time.
  “But this seems to be visible proof that the spot the pilgrims worship today really is the same tomb the Roman Emperor Constantine found in the 4th century and the Crusaders revered. It’s amazing.
  “When we realised what we had found my knees were shaking a little bit.”
  It was opened in the presence of leaders from the Greek and Armenian Orthodox churches and the Franciscan monks, who share responsibility for the church.
  Fredrik adds: “They let the patriarchs of the three churches go in first. They came out with big smiles on their face. Then the monks went in and they were all smiling.
  “We were all getting really curious. Then we went in, looked into the tomb, and saw a lot of rubble. So it wasn’t empty, even though there were no artefacts or bones.”
  Negotiations to open the tomb for vital repairs began in 1959 but all decisions must be agreed by a “status quo committee” of the three religious leaders.
  The committee often struggles to agree, making any changes or repairs notoriously slow and difficult.
  The key to the Church of the Holy Sepulchre is kept by a Muslim family who have unlocked the building every morning for the last 500 years.
  Fredrik says: “Everything has to be approved by the committee, so even changing a candle takes a long time.
  "There is a ladder by the main entrance to the church that hasn’t moved in 240 years and they still haven’t reached a decision. It’s called the immovable ladder. So the fact we were finally allowed to carry out this work is a triumph of negotiation.”
  The tomb attracts thousands of pilgrims every day so the team got less than three days to clean and explore it.
  They used ground penetrating radar and thermographic scanners to record as much information as possible beforehand. It took 35 conservation experts 60 hours to remove the dirt, documenting every step.
  They eventually found the limestone burial bed just hours before they had to reseal the tomb.
  The team gathered so much data it will take months to analyse, after which they will have enough information to create a virtual reconstruction of the tomb that anyone can view. Fredrick says: “Often in archaeology the eureka moment doesn’t happen in the field.
  “It comes when you get home and examine all the data you’ve collected. Who knows what that will tell us.
  “Without bones or artefacts we’ll never be able to say for sure this was the tomb of Christ.
  “That is a matter of faith. It always has been and it probably always will be.”
