At the foot of a mountain peak in the Kidron Valley desert, the Mar Saba Monastery sits 1,500 meters (roughly a mile) away from the town of al-Ubeidiya, east of Bethlehem. The monastery dates back to the fifth century. Saint Saba, among other monks, founded it in 484 based on a unique engineering plan to become one of the oldest inhabited monasteries in the world.
The monastery is one of the most prominent Palestinian archaeological monuments. It is surrounded by magnificent natural sceneries showing the twists and turns of the valley. An 18-meter (59 feet) high tower called the Justinian Tower was erected next to the monastery in the sixth century and was used for observation.
