Petra

Petra ("rock" in Greek) was the remarkable cliff city of the Nabataean Arabs carved into the red sandstone mountains of Edom, southeast of the Dead Sea. It is identified with the biblical Sela ("rock" in Hebrew), the ancient capital of Edom, captured by Amaziah king of Judah who renamed it Joktheel. Isaiah 16:1 refers to Sela in the context of Moabite refugees seeking safety. The Nabataean kingdom centered at Petra flourished from approximately the 4th century B.C. through its Roman incorporation in A.D. 106, and the city's treasury, monasteries, and temples carved directly from rose-red rock make it one of the most spectacular archaeological sites in the world.
