The Garden Tomb - Pilgrimage to the Holy Land

In front of the tomb entrance is a man-made channel through which a stone was rolled back and forth to close or open the doorway.

Then he rolled a stone against the entrance of the tomb. (Mark 15:46b)

Below is a stone that was used to cover a tomb, although this one came from a different location and is too small to have been made for the Garden Tomb.
