Temple of Zeus Jerash
Petra picture - Jerash rose to prominence when it was conquered by the Romans and it was established as a trade city. For a few centuries, Jerash grew to become a prospering Roman city, with theatres, temples, a market place, baths and a forum. After the 3rd century AD, due to wars, invasions, earth quakes, and changing of trade routes, the city declined and was eventually even deserted, only to be repopulated in the 19th century.
