No Christian pilgrim to Jerusalem will miss the Garden of Gethsemane, but there is a natural cave along a narrow passageway from the courtyard of the Tomb of Mary, that they might skip. The grotto is where according to Christian traditions, Judas betrayed Christ with a kiss and where the disciples slept while Jesus prayed a stone's throw away. It had a chapel from the Byzantine period (5th cent.) and archaeological remains from the period are still visible on the site.
