Tomb of the Virgin Mary

Near the Garden of Gethsemane is the tomb of the Virgin Mary.
A church has been built at the site of Mary's tomb inside an underground rock cave. The entrance to the cave is a wide staircase built during twelfth century.
At the foot of the staircase, to the left, is the chapel of Saint Joseph.
On the right side is the entrance to Mary's tomb. We happened to be in the church just as the priests there were beginning to worship. I caught a few seconds of their chanting. (Again, apologies that the video is turned sideways; if anyone knows how to rotate video, please let me know!)
