PETRA, Jordan - “Here, this is the gateway to the monastery, the most beautiful and famous monument of Petra,” said Abraham Mashaleh, 48, a Jordanian native born and raised in Petra who has worked as a guide to the ancient city for over 20 years. He pointed at the narrow passage after a kilometer-long trail through rose-red “siq,” or winding rock gorges soaring over 100 meters up into the sky.
