PetraWritten by Super User
Petra is a highlight not just of Jordan but of the entire Middle East, a sublime and mysterious city that sits as an incomparable jewel of ancient architecture. Petra was once an important stop on a Roman trading route, but was only assimilated into the empire in 106 AD. Until then it had been a stronghold of the Nabataen Arab kingdom, whose knowledge of Greek architectural styles is reflected in their astonishing cliff-bound monuments. Today Petra is a UNESCO World Heritage site.
