El-Deir, Petra, Jordan

Photo: El-Deir monastery at Petra, Jordan
A person standing in the doorway of the Monastery at Petra, Jordan, shows the enormity of the ancient building's entrance. Carved into the sandstone hill by the Nabataeans in the second century A.D., this towering structure, called El-Deir, may have been used as a church or monastery by later societies, but likely began as a temple.
