Welcome to the ancient temple of Al-Khazneh in the desert city of Petra, Jordan. Carved out of a single sandstone rock about 2,000 years ago by the Nabataean people, it is believed to have been a mausoleum for King Aretas IV. Standing 141 feet tall, its massive doorway is framed with towering columns and intricate carvings. It is the most recognizable structure of this "rose city" of temples and tombs carved from pink sandstone.
