At the time of Jesus, Gethsemane covered almost all of the Mount of Olives' western slope; nowadays it encompasses no more than a few hundred metres. The garden is well-tended by the Fransiscans appointed to the task, and many flowers and plants grow among the eight ancient olive trees that remain there. Also in the vacinity is a cave, or grotto, which may well have been the place where the disciples slept while Jesus prayed in his agony.
The rock on which our Lord is said to have prayed is also in Gethsemane, and a church has been built over it. This is the Church of the Agony, or the Church of All Nations.
