 There is also a 150-ton rock that rests on the ground in only two places, and a "womb-cave".Archaeologists have found ceramic artefacts from the Early Iron Age (10th–6th century BC), classical antiquity, and the Middle Ages, as well as a man-made stone altar at the end of the natural cave which proves that it was used as a place of worship.Every day at noon, a ray of sunlight enters the narrow entrance of the cave, and projects itself on the back of cave.
