What made Petra impressive, too, were its many temples. There were religious temples by the hundreds. The best preserved ones seemed to have been cut out by the Nabataeans in Roman times. Though impressive from the outside, Burckhardt saw that inside the temples were pitiful hovels, hardly more than caves. On the outside around the city Burckhardt noted many high places, sacred places of heathen worship so often condemned by Jehovah’s prophets. On these high places the sons of Esau once worshiped their Edomite gods. To make access to the sacred sites easy for the worshiper stairs were cut into the side of the mountain.
