Just driving by a person could easily miss this amazingly in tact piece of Roman history. In fact so magnificent is this place that it nearly rivals Rome. What you experience here is over 6500 years of history and reinvention as different cultures established themselves here over the centuries. After Petra, this is a must see.
Tip: With a Jordan Pass you forgo the visa fee and get access to Jerash ruins, Petra and most other significant historically significant sights in Jordan.
