Behind Saint George's, on the left side as you head down Saladin Street, is a gate marked "Tombeau des Rois." About 6m (20 ft.) down a stone stairway, you'll see a hollowed-out courtyard, with several small cave openings. Inside one are four sarcophagi, covered with carvings of fruit and vines. Despite the name, the tomb is for the family of Queen Helena of the Mesopotamian province of Adiabene, who converted to Judaism in Jerusalem around A.D. 50.
