This is "Skull Hill", or Golgotha, can you see why? It is just right outside the garden.
Here is part of the inside of the tomb where the body would have been.

This is Jer at the Garden Tomb. Catholics believe that Jesus was crucified and buried where the Church of the Holy Sepulcher now stands, but many Protestants disagree and think it was a little down the road in this garden area. There is a lot of evidence for both. Anyway, you can actually see where the stone to this tomb would have been, it's very big, look at the rounded edge on the far right and follow the line all the way around.
