The Mount of Olives (1) is a chain of rounded limestone hills located on the eastern side of Jerusalem and separated from the city by the Kidron Valley. The summit across from the temple mount (2) is about 812 m (2,664 ft) at its highest point and is the one generally referred to in the Bible as the Mount of Olives. It was from a location on the Mount of Olives that Jesus explained the sign of his presence to his disciples.
